Chemical jigsaw puzzles: how do chemists identify molecules?

Front cover of Great ExplanationsA quick thing before I get into this month’s chemistry ramble: I’m guessing that you, lovely reader, enjoy reading about science stuff. Especially stuff written by an amazing crowd of hard-working science communicators, one of whom is yours truly. So, please consider spreading the word about this awesome book: Great Explanations. Or even better, pledge! There are some fabulous rewards at the different pledge levels. Either way, thank you x

Okay, back to it! Recently, a bit of an argument blew up on Twitter regarding what is, and isn’t, in covid vaccinations. The particular substance du jour being graphene oxide. The @TakeThatChem account pointed out that one of the sources being touted by some as ‘evidence’ for its presence (the article in question was by Robert O Young, remember him? Yes, the one that did actual jail time) didn’t describe the use of any sort of technique that could identify graphene oxide. Which, just to be clear, is absolutely not an ingredient in covid vaccinations.

The debate culminated with questions about how, exactly, scientists do identify substances on the molecular level. @TakeThatChem wondered if one of the users who had become embroiled in the debate even understood how a chemist might work out a molecule’s structure, and then posted an image.

This tweet illustrated a technique that can be used to identify molecules.

British students of chemistry first meet images like this somewhere around the age of 17–18, so although this is somewhat advanced, it’s still essentially school-level. Which means that for a chemist, it’s one of those things that’s so familiar that, half the time, we probably forget that the rest of the world will have absolutely no idea what it is.

But for those that have never studied A level chemistry or similar: what is it?

The answer is that it’s a proton NMR, or nuclear magnetic resonance, spectrum. Now, NMR is quite tricky. Bear with me, I’m about to try and explain it in a paragraph…

Here goes: you know magnets? And how, if you put one magnet near another magnet, it moves? Now imagine that certain types of atomic nuclei are basically tiny magnets. If you put them in a really powerful magnetic field, they sort of move. If you then alter that magnetic field, they move as the field varies. A computer records and analyses those changes, and spits out a graph that looks like that one back there – which chemists call a spectrum.

Medical MRIs use essentially the same technology as the one used to generate the spectrum

Did I nail it? There’s a lot more to this, not surprisingly. In particular, radio waves are involved. My quick and dirty explanation is the equivalent of describing a car as a box on wheels – it’s broadly true from a distance if you squint a bit, but if you said it in the presence of a qualified mechanic they’d wince and start muttering words like ‘head gasket’ and ‘brake discs’ and ‘you do know this is a diesel engine, yes?’

Anyway, it’ll do for now. If you’re studying NMR at a more advanced level, take a look at this episode of Crash Course Organic Chemistry written by… someone called Kat Day. No idea who that is 😉

The same technique, by the way, is used in medicine – but there you know it as MRI, or magnetic resonance imaging. It turns out that if you shove a human (or pretty much anything that contains a lot of carbon-based molecules) into a powerful magnetic field, the atomic nuclei do their thing. You might imagine that having all your atoms do some sort of cha-cha would hurt, but no – as anyone who’s ever had an MRI will attest, it’s mostly just very loud and a bit dull. The end result is an image with different contrast for different types of tissue. Fatty tissue, for example, tends to show up as areas of brightness, while bone tends to look darker – so it’s useful for diagnosing all sorts of problems.

Photo of jigsaw pieces

Interpreting a proton NMR spectrum can be a bit like looking at a jigsaw pieces

But back to chemistry. Chemists, preferring a simpler life (haha), are often working with single substances. Or at least trying to. If we imagine a molecule as a picture, looking at a proton NMR spectrum is a bit like looking at a mixed-up jigsaw puzzle of that picture. Each individual piece – or peak – in the spectrum represents an atom or a group of atoms.

Each piece tells you something and, at the same time, it also tells you about the bits that are joined to it. In the same way that you might look at a jigsaw piece and think, ‘well, this has a sticky-out bit so the piece that goes next to it must have an inny-bit,’ chemists look at a spectrum and say, ‘well, this bit looks like this, so its carbon atom must be attached to group of atoms like that.’

Okay, so what do the pieces in the spectrum @TakeThatChem posted show us? Well, reading spectra takes practice but, like most things, if you do that practice, after a while you get into the habit of spotting things straight away.

For example, it’s fairly obvious to me that whatever-it-is it probably has a carboxylic acid (COOH) group, and it definitely has a benzene ring. I can also see that the benzene ring has things bonded to opposite points, in other words, if you numbered the carbons in the ring from 1 to 6, it has things attached at carbon 1 and carbon 4. There’s a chain of carbons, which is branched, and there’s another CH3 group somewhere. To get more precise I’d have to look more carefully at the integrals (the differently-sized ∫ symbols over the peaks), hunt for a data sheet and study the scale on the horizontal axis along the bottom.

The spectrum is of a common drug substance, but which one…

My brain got as far as ‘hm, maybe it’s aspirin, oh no, it can’t be, because…’ before I came across the already-posted answer. I won’t give it away – spoilers, sweetie – but let’s just say it’s a molecule not a million miles different from aspirin.

So yes, chemists do have the means to identify individual molecules, but it requires a fair bit of knowledge and training to both carry out the techniques and to interpret the results. Despite what Hollywood might have us believe, we don’t (yet) have a machine that intones ‘this material is approximately 40% isobutylphenylpropionic acid, captain’ when you plop a sample into it.

The fact that real chemistry (and science in general) is not simple is precisely why pseudoscience peddled by the likes of Robert O Young is so appealing: it’s nice and easy, it follows a sort of ‘common sense’ narrative, it’s not swathed in all sorts of technical language. Anyone can read it and, without any other training, feel as if they understand it perfectly.

None of us knows what we don’t know. If someone comes along with an easy explanation, it’s tempting to believe it – particularly if they go on to play into our anxieties and tell us what we were hoping to hear.

Which brings me to a thread by the lovely Dr Ben Janaway, one tweet of which said, extremely eloquently:

Please do not harass [people protesting covid vaccines]. Please do not blame them. My education is a privilege they have not been afforded. They do not lack intelligence, they lack being taught how to make sense of very complicated things, most of it hidden. What can we do, listen and talk.

Please get vaccinated

His point is a good one. All we can do is keep spreading the word as clearly as possible and just hope that, maybe, it will change one mind somewhere. Because maybe that mind will change another, and maybe sense will spread.

Take care, stay safe, and get vaccinated. Get your flu jab, too, if it’s that time of year in your part of the world.

The Chronicles of the Chronicle Flask: 2019

Happy New Year, everyone! Usually, I write this post in December but somehow things have got away from me this year, and I find myself in January. Oops. It’s still early enough in the month to get away with a 2019 round-up, isn’t it? I’m sure it is.

It was a fun year, actually. I wrote several posts with International Year of the Periodic table themes, managed to highlight the tragically-overlooked Elizabeth Fulhame, squeezed in something light-hearted about the U.K.’s weird use of metric and imperial units and discovered the recipe for synthetic poo. Enjoy!

Newland’s early table of the elements

January started with a reminder that 2019 had been officially declared The Year of the Periodic Table, marking 150 years since Dmitri Mendeleev discovered the “Periodic System”. The post included a quick summary of his work, and of course mentioned the last four elements to be officially named: nihonium (113), moscovium (115), tennessine (117) and oganesson (118). Yes, despite what oh-so-many periodic tables still in widespread use suggest (sort it out in 2020, exam boards, please), period 7 is complete, all the elements have been confirmed, and they all have ‘proper’ names.

February featured a post about ruthenium. Its atomic number being not at all significant (there might be a post about rhodium in 2020 😉). Ruthenium and its compounds have lots of uses, including cancer treatments, catalysis, and exposing latent fingerprints in forensic investigations.

March‘s entry was all about a little-known female chemist called Elisabeth Fulhame. She only discovered catalysis. Hardly a significant contribution to the subject. You can’t really blame all those (cough, largely male, cough) chemists for entirely ignoring her work and giving the credit to Berzelius. Ridiculous to even suggest it.

An atom of Mendeleevium, atomic number 101

April summarised the results of the Element Tales Twitter game started by Mark Lorch, in which chemists all over Twitter tried to connect all the elements in one, long chain. It was great fun, and threw up some fascinating element facts and stories. One of my favourites was Mark telling us that when he cleared out his Grandpa’s flat he discovered half a kilogram of sodium metal as well as potassium cyanide and concentrated hydrochloric acid. Fortunately, he managed to stop his family throwing it all down the sink (phew).

May‘s post was written with the help of the lovely Kit Chapman, and was a little trot through the discoveries of five elements: carbon, zinc, helium, francium and tennessine, making the point that elements are never truly discovered by a single person, no matter what the internet (and indeed, books) might tell you.

In June I wrote about something that had been bothering me a while: the concept of describing processes as “chemical” and “physical” changes. It still bothers me. The arguments continue…

In July I came across a linden tree in a local park, and it smelled absolutely delightful. So I wrote about it. Turns out, the flowers contain one of my all-time favourite chemicals (at least in terms of smell): benzaldehyde. As always, natural substances are stuffed full of chemicals, and anyone suggesting otherwise is at best misinformed, at worst outright lying.

Britain loves inches.

In August I wrote about the UK’s unlikely system of units, explaining (for a given value of “explaining”) our weird mishmash of metric and imperial units. As I said to a confused American just the other day, the UK is not on the metric system. The UK occasionally brushes fingers with the metric system, and then immediately denies that it wants anything to do with that sort of thing, thank you very much. This was my favourite post of the year and was in no way inspired by my obsession with the TV adaptation of Good Omens (it was).

In September I returned to one of my favourite targets: quackery. This time it was amber teething necklaces. These are supposed to work (hmm) by releasing succinic acid from the amber beads into the baby’s skin where it… soothes the baby by… some unexplained mechanism. They don’t work and they’re a genuine choking hazard. Don’t waste your money.

October featured a post explaining why refilling plastic bottles might not be quite as simple as you thought. Sure, we all need to cut down on plastic use, but there are good reasons why shops have rules about what you can, and can’t, refill and they’re not to do with selling more bottles.

November continued the environmental theme with a post was all about some new research into super-slippery coatings that might be applied to all sorts of surfaces, not least ceramic toilet bowls, with the goal of saving some of the water that’s currently used to rinse and clean such surfaces. The best bit about this was that I discovered that synthetic poo is a thing, and that the recipe includes miso. Yummy.

Which brings us to… December, in which I described some simple, minimal-equipment electrolysis experiments that Louise Herbert from STEM Learning had tested out during some teaching training exercises. Got a tic tac box, some drawing pins and a 9V battery? Give it a go!

Well, there we have it. That’s 2019 done and dusted. It’s been fun! I wonder what sort of health scares will turn up for “guilty January”? Won’t be long now…

The Chronicles of the Chronicle Flask: 2017

We’ve made it! Not only to 2018 (which was starting to look doubtful earlier in the year), but also to the Chronicle Flask’s 100th post. Which doesn’t seem that many, really, but since posts on here frequently run to 1500 words, that adds up to a rather more impressive-sounding 150,000 words or so. I mean, that’s like… half a Brandon Sanderson novel. Oh.

Anyway, it’s time for a yearly round-up. Here goes!

Last January I began with a post about acrylamide. We’d all been enjoying lots of lovely crispy food over Christmas; it was time to tell us about the terrible dangers of such reckless indulgence. The newspapers were covered with pictures of delicious-looking chips, toast and roast potatoes alongside scary headlines such as:  “Crunchy toast could give you cancer, FSA warns”. The truth was not quite so dramatic. Acrylamide does form when foods are cooked to crispiness, and it is potentially harmful, but the quantities which form in food are tiny, and very unlikely to cause you any serious harm unless you literally live on nothing but burnt toast. The FSA (Food Standards Agency) hadn’t significantly revised their guidelines, it turned out, but were in fact only suggesting that the food industry should be mindful of acrylamide levels in food and seek to reduce them as much as possible. That wouldn’t have made for quite such a good “your food is going to killllll you!” story though, I suppose.

In February the spikey topic of vaccination came up. Again. Vaccines are awesome. They protect us from deadly diseases. No, I don’t want to hear any nonsense about “Big Pharma“, and I definitely don’t want to hear how “natural immunity” is better. It’s not. At best, it might provide a similar level of protection (but not in every case), but it comes with having to suffer through a horrible, dangerous disease, whereas vaccination doesn’t. It ought to be a no-brainer. Just vaccinate your kids. And yourself.

It was Red Nose Day in the UK in March, which brought some chemistry jokes. Turns out all the best ones aren’t gone, after all. Did you hear about the PhD student who accidentally cooled herself to absolute zero? She’s 0K now.

April brought a post which ought to have been an April Fool’s joke, but wasn’t. Sceptics often point out that homeopathy is just sugar and water, but the trouble is, sometimes, it’s not. There’s virtually no regulation of homeopathy. As far as I’ve been able to establish, no one tests homeopathic products; no one checks the dilutions. Since a lot of the starting materials are dangerously toxic substances such as arsenic, belladona, lead and hemlock, this ought to worry people more than it does. There has been more than one accidental poisoning (perhaps most shockingly, one involving baby teething products). It really is time this stuff was banned, maybe 2018 will be the year.

In May I turned to something which was to become a bit of a theme for 2017: alkaline water. It’s not so much that it doesn’t do anything (although it really doesn’t), more the fact that someone is charging a premium for a product which you could literally make yourself for pennies. It’s only a matter of dissolving a pinch of baking soda (sodium bicarbonate) in some water.

June brought a selection of periodic tables because, well, why not? This is a chemistry blog, after all! And now we’ve finally filled up period seven they do have a rather elegant completness. 2019, by the way, has just been announced as the International Year of the Periodic Table of Chemical Elements, to coincide with IUPAC’s 100th anniversary and the 150th anniversary of Mendeelev’s discovery of periodicity (his presentation, The Dependence Between the Properties of of the Atomic Weights of the Elements, was made on 6th March 1869). Looks like 2019 will be an exciting year for chemists!

In July it was back to the nonsense of alkaline diets again, when Robert O. Young was finally sentenced to 3 years, 8 months in custody for conning vulnerable cancer patients into giving him large sums of money for ineffective and dangerous treatments. Good. Moving on.

August brought me back to a post that I’d actually started earlier in the year when I went to a March for Science event in April. It was all about slime, and August seemed like a good time to finally finish it, with the school holidays in full swing – what could be more fun on a rainy day at home than making slime? Slime was a bit of a 2017 craze, and there have been a few stories featuring children with severely irritated skin. But is this likely to be caused by borax? Not really. Turns out it’s actually very safe. Laundry detergents in general, not so much. In short, if you want to make slime the traditional way with PVA glue and borax, fill your boots. (Not really – your parents will be uninpressed.)

In September it was back to quackery: black salve. A nasty, corrosive concoction which is sold as a cancer cure. It won’t cure your cancer. It will burn a nasty great big hole in your skin. Do not mess with this stuff.

October carried on in a similar vein, literally. This time with a piece about naturopaths recommending hydrogen peroxide IVs as a treatment for lots of things, not least – you guessed it – cancer. Yes, hydrogen peroxide. The stuff you used to bleach hair. Intraveneously. Argh.

The puking pumpkin!

The end of the month featured a far better use for hydrogen peroxide, that of the puking pumpkin. Definitely one to roll out if, for any reason, you ever find yourself having to demonstrate catalysis.

November brought us, somewhat unseasonally, to tomatoes. Where is the best place to store them? Fridge or windowsill? Turns out the answer involves more chemistry than you might have imagined.

And then, finally, December. Looking for a last-minute Christmas gift? Why not buy a case of blk water? I mean, other than it’s an exorbitantly priced bottle of mysterious black stuff which doesn’t do any of the things it claims to do, and might actually get its colour from coal deposits, that is.

And that, dear friends and followers, is it for 2017! Happy New Year! Remember to be sceptical when the inevitable “deadly food” story appears in a few weeks….

Hydrogen peroxide: another deadly alternative?

I’m sure most people have heard of hydrogen peroxide. It’s used as a disinfectant and, even if you’ve never used it for that, you probably at least know that it’s used to bleach hair. It’s where the phrase “peroxide blonde” comes from, after all. Hydrogen peroxide, and its formula, is so famous that there’s an old chemistry joke about it:

(I have no idea who to credit for the original drawing – if it’s you, leave me a message.)

To save you squinting at the text, it goes like this:
Two men walk into a bar. The first man says, “I’ll have some H2O.”
The second man says, “I’ll have some H2O, too.”
The barman brings the drinks. The second man dies horribly.

Now I think about it, it’s not a terribly funny joke.

Hydrogen peroxide has an extra oxygen atom in the middle.

Never mind. You get the idea. H2O2 (“H2O, too”) is the formula for hydrogen peroxide. Very similar to water’s formula, except with an extra oxygen atom in the middle. In fact, naturopaths – purveyors of alternative therapies – often refer to hydrogen peroxide as “water with extra oxygen”. But this is really misleading because, to torture a metaphor, that extra oxygen makes hydrogen peroxide the piranha to water’s goldfish.

Water, as we know, is pretty innocuous. You should try not to inhale it obviously, or drink more than about six litres in one go, but otherwise, its pretty harmless. Hydrogen peroxide, on the other hand, not so much. The molecule breaks apart easily, releasing oxygen. That makes it a strong oxidising agent. It works as a disinfectant because it basically blasts cells to pieces. It bleaches hair because it breaks down pigments in the hair shaft. And, as medical students will tell you, it’s also really good at cleaning up blood stains – because it oxidises the iron in haemoglobin to Fe3+, which is a pale yellow colour*.

Dilute hydrogen peroxide is readily available.

In its dilute form, hydrogen peroxide is a mild antiseptic. Three percent and even slightly more concentrated solutions are still readily available in high-street pharmacies. However, even these very dilute solutions can cause skin and eye irritation, and prolonged skin contact is not recommended. The trouble is, while it does destroy microbes, it also destroys healthy cells. There’s been a move away from using hydrogen peroxide for this reason, although it is still a popular “home” remedy.

More concentrated** solutions are potentially very dangerous, causing severe skin burns. Hydrogen peroxide is also well-known for its tendency to react violently with other chemicals, meaning that it must be stored, and handled, very carefully.

All of which makes the idea of injecting into someone’s veins particularly horrific.

But this is exactly what some naturopaths are recommending, and even doing. The idea seems to have arisen because hydrogen peroxide is known to damage cancer cells. But so will a lot of other dangerous substances – it doesn’t mean it’s a good idea to inject them. Hydrogen peroxide is produced by certain immune cells in the body, but only in a very controlled and contained way. This is definitely a case where more isn’t necessarily better.

The use of intravenous hydrogen peroxide appears to have begun in America, but it may be spreading to the UK. The website yestolife.org.uk, which claims to empower people with cancer to “make informed decisions”, states “The most common form of hydrogen peroxide therapy used by doctors calls for small amounts of 30% reagent grade hydrogen peroxide added to purified water and administered as an intravenous drip.”

30% hydrogen peroxide is really hazardous stuff. It’s terrifying that this is being recommended to vulnerable patients.

Other sites recommend inhaling or swallowing hydrogen peroxide solutions, both of which are also potentially extremely dangerous.

If anyone ever suggests a hydrogen peroxide IV, run very fast in the other direction.

In 2004 a woman called Katherine Bibeau died after receiving intravenous hydrogen peroxide treatment from James Shortt, a man from South Carolina who called himself a “longevity physician”. According to the autopsy report she died from systemic shock and DIC – the formation of blood clots in blood vessels throughout the body. When her body arrived at the morgue, she was covered in purple-black bruises.

Do I need to state the obvious? If anyone suggests injecting this stuff, run. Run very fast, in the other direction. Likewise if they suggest drinking it. It’s a really stupid idea, one that could quite literally kill you.


* As anyone who’s ever studied chemistry anywhere in my vicinity will tell you, “iron three is yellow, like wee.”


** The concentration of hydrogen peroxide is usually described in one of two ways: percentage and “vol”. Percentage works as you might expect, but vol is a little different. It came about for practical, historical reasons. As Prof. Poliakoff comments in this video, hydrogen peroxide is prone to going “flat” – leave it in the bottle for long enough and it gradually decomposes until what you actually have is a bottle of ordinary water. Particularly in the days before refrigeration (keeping it cold slows down the decomposition) a bottle might be labelled 20%, but actually contain considerably less hydrogen peroxide.

What to do? The answer was quite simple: take, say, 1 ml of hydrogen peroxide, add something which causes it to decompose really, really fast (lots of things will do this: potassium permanganate, potassium iodide, yeast, even liver) and measure the volume of oxygen given off. If your 1 ml of hydrogen peroxide produces 10 ml of oxygen, it’s 10 vol. If it produces 20, it’s 20 vol. And so on. Simple. 3% hydrogen peroxide, for the record, is about 10 vol***. Do not mix up these numbers.


*** Naturally, there are mole calculations to go with this. Of course there are. For A-level Chemists, here’s the maths (everyone else can tune out; I’m adding this little footnote because I found this information strangely hard to find):

Hydrogen peroxide decomposes as shown in this equation:
2H2O2 –> 2H2O + O2

Let’s imagine we decompose 1 ml of hydrogen peroxide and obtain 10 mls of oxygen.

Assuming the oxygen gas occupies 24 dm3 (litres), or 24000 mls, at standard temperature and pressure, 10 mls of oxygen is 10 / 24000 = 0.0004167 moles. But, according to the equation, we need two molecules of hydrogen peroxide to make one molecule of oxygen, so we need to multiply this number by two, giving us 0.0008333 moles.

To get the concentration of the hydrogen peroxide in the more familar (to chemists, anyway) mol dm-3, just divide that number of moles by the volume of hydrogen peroxide. In other words:

0.0008333 mols / 0.001 dm3 = 0.833 mol dm-3

If you really want to convert this into a percentage by mass (you can see why people stick with “vol” now, right?), then:

0.833 mol (in the litre of water) x 34 g mol-1 (the molecular mass of H2O2)
= 28.32 g (in 1000 g of water)

Finally, (28.32 / 1000) x 100 = 2.8% or, rounding up, 3%

In summary (phew):
10 vol hydrogen peroxide = 0.83 mol dm-3 = 3%

Absurd alkaline ideas – history, horror and jail time

I’ve written about the absurdity of alkaline diets before, and found myself embroiled in more than one argument about the idea.

To sum up quickly, it’s the notion that our bodies are somehow “acidic”, and if only we could make them “alkaline” all our health problems – cancer included – would disappear. The way you make your body “alkaline” is, mainly, by eating lots of vegetables and some fruits (particularly citrus fruits – yes, I know, I know).

The eating fruit and vegetables bit aside (they’re good for you, you should eat them), it’s all patent nonsense. Our bodies aren’t acidic – well, other than where they’re supposed to be acidic (like our stomachs) – and absolutely nothing we eat or drink can have any sort of effect on blood pH, which is kept firmly between 7.35-7.45 by (mainly) our lungs and kidneys. And if your kidneys or lungs are failing, you need something a little stronger in terms of medical intervention than a slice of lemon.

But who first came up with this crazy idea?

Claude Bernard carried out experiments on rabbits.

Actually, we can probably blame a nineteenth century French biologist and physiologist, Claude Bernard, for kicking the whole thing off, when he noticed that if he changed the diet of rabbits from largely plant-based to largely animal-based (i.e. from herbivorous to carnivorous) their urine became more acidic.

This observation, followed by a lot of speculation by nutritionists and some really quite impressively dodgy leaps of reasoning (by others, I should stress – not Bernard himself), has lead us to where we are now: umpty-million websites and books telling anyone who will listen that humans need to cut out all animal products to avoid becoming “acidic” and thus ill.

Bernard’s rabbits were, it seems, quite hungry when he got them – quite possibly they hadn’t been fed – and he immediately gave them boiled beef and nothing else. Meat contains the amino acids cysteine and methionine, both of which can produce acid when they’re metabolised (something Bernard didn’t know at the time). The rabbits excreted this in their urine, which probably explains why it became acidic.

Now, many of you will have noticed several problems here. Firstly, rabbits are herbivores by nature (they do not usually eat meat in the wild). Humans aren’t herbivores. Humans are omnivores, and we have quite different digestive processes as a result. It’s not reasonable to extrapolate from rabbits to humans when it comes to diet. Plus, even the most ardent meat-lover probably doesn’t only eat boiled beef – at the very least people usually squeeze in a battered onion ring or a bit of coleslaw along the way. Most critically of all, urine pH has no direct relationship with blood pH. It tells us nothing about the pH of “the body” (whatever we understand that to mean).

The notion that a plant-based diet is somehow “alkaline” should really have stayed in the 19th century where it belonged, and at the very least not limped its way out of the twentieth. Unfortunately, somewhere in the early 2000s, a man called Robert O Young got hold of the idea and ran with it.

Young’s books – which are still available for sale at the time of writing – describe him as “PhD”, even though he has no accredited qualification.

Boy, did he run with it. In 2002 he published a book called The pH Miracle, followed by The pH Miracle for Diabetes (2004), The pH Miracle for Weight Loss (2005) and The pH Miracle Revised (2010).

All of these books describe him either as “Dr Robert O Young” or refer to him as “PhD”. But he has neither a medical qualification nor a PhD, other than one he bought from a diploma mill – a business that offers degrees for money.

The books all talk about “an alkaline environment” and state that so-called acidic foods and drinks (coffee, tea, dried fruit, anything made with yeast, meat and dairy, amongst other foodstuffs) should be avoided if not entirely eliminated.

Anyone paying attention will quickly note that an “alkaline” diet is basically a very restrictive vegan diet. Most carbohydrate-based foods are restricted, and lots of fruits and nuts fall into the “moderately” and “mildly” acidic categories. Whilst a vegan diet can be extremely healthy, vegans do need to be careful that they get the nutrients they need. Restricting nuts, pulses, rice and grains as well as removing meat and dairy could, potentially, lead to nutritional deficiencies.

Young also believes in something called pleomorphism, which is a whole other level of bonkers. Essentially, he thinks that viruses and bacteria aren’t the cause of illnesses – rather, the things we think are viruses and bacteria are actually our own cells which have changed in response to our “acidic environments”. In Young’s mind, we are making ourselves sick – there is one illness (acidosis) and one cure (his alkaline diet).

It’s bad enough that he’s asserting such tosh and being taken seriously by quite a lot of people. It’s even worse that he has been treating patients at his ranch in California, claiming that he could “cure” them of anything and everything, including cancer.

One of his treatments involved intravenous injections of solutions of sodium hydrogen carbonate, otherwise known as sodium bicarbonate or baking soda. This common cookery ingredient does produce an alkaline solution (about pH 8.5) when dissolved in water, but remember when I said blood pH was hard to shift?

Well, it is, and for good reason. If blood pH moves above the range of 7.35-7.45 it causes a condition called alkalosis. This can result in low blood potassium which in turn leads to muscle weakness, pain, and muscle cramps and spasms. It can also cause low blood calcium, which can ultimately result in a type of seizure. Putting an alkaline solution directly into somone’s blood is genuinely dangerous.

And this is before we even start to consider the fact that someone who was not a medical professional was recommending, and even administering, intravenous drips. Which, by the way, he was reportedly charging his patients $550 a pop to receive.

Young came to the attention of the authorities several times, but always managed to wriggle out of trouble. That is, until 2014, when he was arrested and charged with practising medicine without a license and fraud. In February last year, he was found guilty, but a hung jury caused complications when they voted 11-1 to convict on the two medical charges, but deadlocked 8-4 on fraud charges.

Finally, at the end of June 2017, he was sentenced. He was given three years, eight months in custody, but due to the time he’s already spent in custody and under house arrest, he’s likely to actually serve five months in jail.

He admitted that he illegally treated patients at his luxury Valley Center ranch without any medical or scientific training. Perhaps best of all, he was also made to publicly declare that he is not microbiologist, hematologist, medical doctor or trained scientist, and that he has no post-highschool educational degrees from any accredited school.

Prosecuting Deputy District Attorney Gina Darvas called Young the “Wizard of pHraud”, which is rather apt. Perhaps the titles on his books could be edited to read “Robert O Young, pHraud”?

Alkaline water: if you like it, why not make your own?

Me* reading the comments section on the Amazing Alkaline Lemons post (*not actually me)

Alkaline water seems to be a trend at the moment. Not quite so much in the UK, yet, but more so in the US where it appears you can buy nicely-packaged bottles with the numbers like 8 and 9.5 printed in large, blue letters on their sides.

It’s rather inexplicable, because drinking slightly alkaline water does literally NOTHING for your health. You have a stomach full of approximately 1 M hydrochloric acid (and some other stuff) which has an acidic pH of somewhere between 1.5 and 3.5. This is entirely natural and normal – it’s there to kill any bugs that might be present in your food.

Chugging expensive water with an alkaline pH of around 9 will neutralise a bit of that stomach acid (bringing the pH closer to a neutral value of 7), and that’s all it will do. A stronger effect could be achieved with an antacid tablet (why isn’t it antiacid? I’ve never understood that) costing around 5p. Either way, the effect is temporary: your stomach wall contains special cells which secrete hydrochloric acid. All you’re doing by drinking or eating alkaline substances is keeping them busy.

(By the way, I’m not recommending popping antacids like sweeties – it could make you ill with something called milk-alkali syndrome, which can lead to kidney failure.)

Recently, a video did the rounds of a woman testing various bottled waters, declaring the ones with slightly acidic pHs to be “trash” and expressing surprise that several brands, including Evian, were pH neutral. The horror. (For anyone unsure, we EXPECT water to have a neutral pH.)

Such tests are ridiculous for lots of reasons, not least because she had tiny amounts of water in little iddy-biddy cups. Who knows how long they’d been sitting around, but if it was any length of time they could well have absorbed some atmospheric carbon dioxide. Carbon dioxide is very soluble, and it forms carbonic acid when it dissolves in water which, yes, would lower the pH.

Anyway, there’s absolutely nothing harmful about drinking water containing traces of acid. It doesn’t mean the water is bad. In fact, if you use an ion exchange filter (as found in, say, Brita filter jugs) it actually replaces calcium ions in the water with hydrogen ions. For any non-chemists reading this: calcium ions are the little sods that cause your kettle to become covered in white scale (I’m simplifying a bit). Hydrogen ions make things acidic. In short, less calcium ions means less descaling, but the slight increase in hydrogen ions means a lower pH.

So, filtered water from such jugs tends to be slightly acidic. Brita don’t advertise this fact heavily, funnily enough, but it’s true. As it happens, I own such a filter, because I live in an area where the water is so hard you can practically use it to write on blackboards. After I bought my third kettle, second coffee machine and bazillionth bottle of descaler, I decided it would be cheaper to use filtered water.

I also have universal indicator strips, because the internet is awesome (when I was a kid you couldn’t, easily, get this stuff without buying a full chemistry set or, ahem, knowing someone who knew someone – now three clicks and it’s yours in under 48 hours).

The pH of water that’s been through a (modern) ion-exchange filter tends to be slightly acidic.

The water in the glass was filtered using my Brita water filter and tested immediately. You can see it has a pH of about 5. The water straight from the tap, for reference, has a pH of about 7 (see the image below, left-hand glass).

The woman in the YouTube video would be throwing her Brita in the trash right now and jumping up and down on it.

So, alkaline water is pretty pointless from a health point of view (and don’t even start on the whole alkaline diet thing) but, what if you LIKE it?

Stranger things have happened. People acquire tastes for things. I’m happy to accept that some people might actually like the taste of water with a slightly alkaline pH. And if that’s you, do you need to spend many pounds/dollars/insert-currency-of-choice-here on expensive bottled water with an alkaline pH?

Even more outlandishly, is it worth spending £1799.00 on an “AlkaViva Vesta H2 Water Ionizer” to produce water with a pH of 9.5? (This gizmo also claims to somehow put “molecular hydrogen” into your water, and I suppose it might, but only very temporarily: unlike carbon dioxide, hydrogen is very insoluble. Also, I’m a bit worried that machine might explode.)

Fear not, I am here to save your pennies! You do not need to buy special bottled water, and you DEFINITELY don’t need a machine costing £1.8k (I mean, really?) No, all you need is a tub of….

… baking soda!

Yep, good old sodium bicarbonate, also known as sodium hydrogencarbonate, bicarb, or NaHCO3. You can buy a 200 g tub for a pound or so, and that will make you litres and litres and litres of alkaline water. Best of all, it’s MADE for baking, so you know it’s food grade and therefore safe to eat (within reason, don’t eat the entire tub in one go).

All you need to do is add about a quarter of a teaspoon of aforementioned baking soda to a large glass of water and stir. It dissolves fairly easily. And that’s it – alkaline water for pennies!

Me* unconvinced by the flavour of alkaline water (*actually me).

Fair warning, if you drink a lot of this it might give you a bit of gas: once the bicarb hits your stomach acid it will react to form carbon dioxide – but it’s unlikely to be worse than drinking a fizzy drink. It also contains sodium, so if you’ve been told to watch your sodium intake, don’t do this.

If I had fewer scruples I’d set up shop selling “dehydrated alkaline water, just add water”.

Sigh. I’ll never be rich.

Hazardous homeopathy: ‘ingredients’ that ought to make you think twice

Would you take a medicine made with arsenic? Or deadly nightshade? Lead? Poison ivy?

You’d ask some serious questions first, at least, wouldn’t you? Is it definitely safe? Or, more accurately, are the odds better than even that it will make me better without causing horrible side-effects? Or, you know, killing me?

There ARE medicines that are legitimately made from highly toxic compounds. For example, the poison beloved of crime writers such as Agatha Christie, arsenic trioxide, is used to treat acute promyelocytic leukemia in patients who haven’t responded to other treatments. Unsurprisingly, it’s not without risks. Side-effects are unpleasant and common, affecting about a third of patients who take it. On the other hand, acute promyelocytic leukemia is fatal if untreated. A good doctor would talk this through with a patient, explain both sides, and leave the final choice in his or her properly-informed hands. As always in medicine, it’s a question of balancing risks and benefits.

Would you trust something with no proven benefit and a lot of potential risk? There are, it turns out, a swathe of entirely unregulated mixtures currently being sold in shops and online which clearly feature the substances I listed at the beginning. And more. Because they are all, supposedly, the starting materials in certain homeopathic remedies.

Homeopaths like to use unfamiliar, usually Latin-based, names which somewhat disguise the true nature of their ingredients. Here’s a short, but by no means comprehensive, list. (You might find remedies labelled differently but these are, as far as I can tell, the most common names given to these substances.)

If you haven’t heard of some of these, I do urge you to follow the links above, which will largely take you pages detailing their toxicology. Spoiler: the words “poison”, “deadly” and “fatal” feature heavily. These are nasty substances.

There are some big ironies here, and I’m not referring to the metal. For example, a common cry of anti-vaccinationists is that vaccines contain animal tissues – anything and everything from monkey DNA to dog livers. But many also seem to be keen to recommend homeopaths and courses of homeoprophylaxis – so-called “homeopathic vaccines” – which use bodily fluids such as pus and blood as starting materials.

Now, at this point I’m sure some of you are thinking, hang on a minute: aren’t you always telling us that “the dose makes the poison“? And aren’t homeopathic remedies diluted so much that none of the original substance remains, so they’re just placebos?

Yes, I am, and yes, they are.

Does anyone test homeopathic remedies to make sure there’s nothing in them….?

In THEORY. But here’s the problem: who’s testing these mixtures to make sure that the dilutions are done properly? And how exactly are they doing that (if they are)?

One technique that chemists use to identify tiny quantities of substance is gas chromatography (GC). This is essentially a high-tech version of that experiment you did at school, where you put some dots of different coloured ink on a piece of filter paper and watched them spread up the paper when you put it in some water.

GC analysis is brilliant at identifying tiny quantities of stuff. 10 parts per million is no problem for most detectors, and the most sensitive equipment can detect substances in the parts per billion range. Homeopathy dilutions are many orders of magnitude higher than this (30c, for example, means a dilution factor of 1060), but this doesn’t matter – once you get past 12c (a factor of 1024) you pass the Avogadro limit.

This is because Avogadro’s number, which describes the number of molecules in what chemists call a “mole” of a substance, is 6×1023. For example, if you had 18 ml of water in a glass, you’d have 6×1023 molecules of H2O. So you can see, if you’ve diluted a small sample by a factor of 1024 – more than the total number of molecules of water you had in the first place – the chances are very good that all you have is water. There will be none of the original substance left. (This, by the way, is of no concern to most homeopaths, who believe that larger dilutions magically produce a stronger healing effect.)

What if the sample ISN’T pure water after it’s been diluted?

If you carried out GC analysis of such a sample, you should find just pure water. Indeed, if you DIDN’T find pure water, it should be cause for concern. Potassium cyanide, for example, is toxic at very low levels. The lethal dose is is only 0.2-0.3 grams, and you’d suffer unpleasant symptoms long before you were exposed to that much.

So what if the dilutions somehow go wrong? What if some sample gets stuck in the bottle? Or on the pipette? Or a few dilution steps get skipped for some reason?

Are these largely unregulated companies rigorously quality-checking their remedies?

Well, maybe. It’s possible some producers are testing their raw materials for purity (ah yes, another question: they CLAIM they’re starting with, say, arsenic, but can we be certain?), and perhaps testing the “stability” of their products after certain periods of time (i.e. checking for bacterial growth), but are they running tests on the final product and checking that, well, there’s nothing in it?

And actually, isn’t this a bit of a conflict? If the water somehow “remembers” the chemical that was added and acquires some sort of “vibrational energy”, shouldn’t that show up somehow in GC analysis or other tests? If your tests prove it’s pure water, indistinguishable from any other sample of pure water, then… (at this point homeopaths will fall back on arguments such as “you can’t test homeopathy” and “it doesn’t work like that”. The name for this is special pleading.)

A warning was issued in the U.S. after several children became ill.

Am I scaremongering? Not really. There’s at least one published case study describing patients who suffered from arsenic poisoning after using homeopathic preparations. In January this year the U.S. Food and Drug Administration issued a warning about elevated levels of belladonna (aka deadly nightshade) in some homeopathic teething products. Yes, teething products. For babies. This warning was issued following several reports of children becoming ill after using the products. The FDA said that its “laboratory analysis found inconsistent amounts of belladonna, a toxic substance, in certain homeopathic teething tablets, sometimes far exceeding the amount claimed on the label.”

Now, admittedly, I’m based in the U.K. and these particular teething remedies were never readily available here. But let’s just type “homeopathy” into the Boots.com (the British high-street pharmacy) website and see what pops up… ah yes. Aconite Pillules, 30c, £6.25 for 84.

What happens if you search for “homeopathy” on the Boots.com website?

Have you been paying attention lovely readers? Aconite is…. yes! Monkshood! One of the most poisonous plants in the garden. Large doses cause instant death. Smaller doses cause nausea and diarrhea, followed by a burning and tingling sensation in the mouth and abdomen, possibly muscle weakness, low blood pressure and irregular heartbeat.

I must stress at this point that there is no suggestion, absolutely none whatsoever, that any of the products for sale at Boots.com has ever caused such symptoms. I’m sure the manufacturers check their preparations extremely carefully to ensure that there’s absolutely NO aconite left and that they really are just very small, very expensive, sugar pills.

Well, fairly sure.

In summary, we seem to be in a situation where people who proclaim that rigorously-tested and quality-controlled pharmaceuticals are “toxic” also seem to be happy to use unregulated homeopathic remedies made with ACTUALLY toxic starting materials.

I wonder if the new “documentary” about homeopathy, Just One Drop, which is being screened in London on the 6th of April will clarify this awkward little issue? Somehow, I doubt it. Having watched the trailer, I think it’s quite clear which way this particular piece of film is going to lean.

One last thing. Some homeopathic mixtures include large quantities of alcohol. For example, the Bach Original Flower Remedies are diluted with brandy and contain approximately 27% alcohol (in the interests of fairness, they do also make alcohol-free versions of some of their products and, as I’ve recently learned, they may not be technically homeopathic). Alcohol is a proven carcinogen. Yes, I know, lots of adults drink moderate quantities of alcohol regularly and are perfectly healthy, and the dose from a flower remedy is minuscule, but still, toxins and hypocrisy and all that.

There are cheaper ways to buy brandy than Bach Flower Remedies.

Amusingly, the alcohol in these remedies is described an “inactive” ingredient. It’s more likely to be the only ACTIVE ingredient. And since Flower Remedies retail for about £7 for 20 ml (a mighty £350 a litre, and they’re not even pure brandy) may I suggest that if you’re looking for that particular “medicine” you might more wisely spend your money on a decent bottle of Rémy Martin?

The Chronicles of the Chronicle Flask: 2016

2016 is limping to its painful conclusion, still tossing out last-minute nasty surprises like upturned thumb tacks in the last few metres of a marathon. But the year hasn’t been ALL bad. Some fun, and certainly interesting, things happened too. No, really, they did, honestly.

So with that in mind, let’s have a look back at 2016 for the Chronicle Flask….

January kicked off with a particularly egregious news headline in a well-known broadsheet newspaper: Sugar found in ketchup and Coke linked to breast cancer. Turns out that the sugar in question was fructose. Yes, the sugar that’s in practically everything, and certainly everything that’s come from a plant. So why did the newspaper in question choose ketchup and Coke for their headline instead of, oh, say, fruit juice or honey? Surely not just in an effort to sell a few more newspapers after the overindulgent New Year celebrations. Surely.

octarineThere was something more lighthearted to follow when IUPAC  verified the discoveries of elements 113, 115, 117 and 118. This kicked off lots of speculation about the elements’ eventual names, and the Chronicle Flask suggested that one of them should be named Octarine in honour of the late Sir Terry Pratchett. Amazingly, this suggestion really caught everyone’s imagination. It was picked up in the national press, and the associated petition got over 51 thousand signatures!

In February I wrote a post about the science of statues, following the news that a statue to commemorate Sir Terry Pratchett and his work had been approved by Salisbury City Council. Did you know that there was science in statues? Well there is, lots. Fun fact: the God of metalworking was called Hephaestus, and the Greeks placed dwarf-like statues of him near their Hearths – could this be where the fantasy trope of dwarves as blacksmiths originates?

MCl and MI are common preservatives in cosmetic products

MCl and MI are common preservatives in cosmetic products

My skeptical side returned with a vengeance in March after I read some online reviews criticising a particular shampoo for containing a substance known as methylchloroisothiazolinone. So should you be scared of your shampoo? In short, no. Not unless you have a known allergy or particularly sensitive skin. Otherwise, feel free to the pick your shampoo based on the nicest bottle, the best smell, or the forlorn hope that it will actually thicken/straighten/brighten your hair as promised, even though they never, ever, ever do.

Nature Chemistry published Another Four Bricks in the Wall in April – a piece all about the potential names of new elements, partly written by yours truly. The month also brought a sinus infection. I made the most of this opportunity by writing about the cold cure that’s 5000 years old. See how I suffer for my lovely readers? You’re welcome.

In May I weighed in on all the nonsense out there about glyphosate (and, consequently, learned how to spell and pronounce glyphosate – turns out I’d been getting it wrong for ages). Is it dangerous? Nope, not really. The evidence suggests it’s pretty harmless and certainly a lot safer than most of its alternatives.

may-facebook-postSomething else happened in May: the Chronicle Flask’s Facebook page received this message in which one of my followers told me that my post on apricot kernels had deterred his mother from consuming them. This sort of thing makes it all worthwhile.

In June the names of the new elements were announced. Sadly, but not really very surprisingly, octarine was not among them. But element 118 was named oganesson and given the symbol Og. Now, officially, this was in recognition of the work of Professor Yuri Oganessian, but I for one couldn’t help but see a different reference. Mere coincidence? Surely not.

July brought another return to skepticism. This time, baby wipes, and in particular a brand that promise to be “chemical-free”. They’re not chemical-free. Nothing is chemical-free. This is a ridiculous label which shouldn’t be allowed (and yet, inexplicably, is still in use). It’s all made worse by the fact that Water Wipes contain a ‘natural preservative’ called grapefruit seed extract which, experiments have shown, only actually acts as a preservative when it’s contaminated with synthetic substances. Yep. Turns out some of Water Wipes claims are as stinky as the stuff they’re designed to clean up.

August brought the Olympics, and speculation was rife about what, exactly, was causing the swimming pools to turn such strange shades of green. Of course, the Chronicle Flask knew the correct solution…

August also saw MMS and CD reared their ugly heads on social media again. CD (chlorine dioxide) is, lest we forget, a type of bleach solution which certain individuals believe autistic children should be made to drink to ‘cure’ them. Worse, they believe such children should be forced to undergo daily enemas using CD solutions. I wrote a summary page on MMS (master mineral solution) and CD, as straight-up science companion to the commentary piece I wrote in 2015.

mugsSeptember took us back to pesticides, but this time with a more lighthearted feel. Did you know that 99.99% of all the pesticides you consume are naturally-occurring? Well, you do if you regularly read this blog. The Chronicle Flask, along with MugWow, also produced a lovely mug. It’s still for sale here, if you need a late Christmas present… (and if you use the code flask15 you’ll even get a discount!)

In October, fed up with endless arguments about the definition of the word ‘chemical’ I decided to settle the matter once and for all. Kind of. And following that theme I also wrote 8 Things Everyone Gets Wong About ‘Scary’ Chemicals for WhatCulture Science.

Just in case that wasn’t enough, I also wrote a chapter of a book on the missing science of superheroes in October. Hopefully we should see it in print in 2017.

Sparklers are most dangerous once they've gone out.

Sparklers are most dangerous once they’ve gone out.

I decided to mark Fireworks Night in November by writing about glow sticks and sparklers. Which is riskier? The question may not be as straightforward as you’d imagine. This was followed by another WhatCulture Science piece, featuring some genuinely frightening substances: 10 Chemicals You Really Should Be Scared Of.

And that brings us to December, and this little summary. I hope you’ve enjoyed the blog this year – do tell your friends about it! Remember to follow @ChronicleFlask on Twitter and like fb.com/chronicleflask on Facebook – both get updated more or less daily.

How to win an argument about homeopathy

Screen Shot 2015-09-25 at 23.41.14

Jeremy Corbyn appeared to support homeopathy, five years ago.

Homeopathy has been in the news (again) lately. Someone managed to dig up a 2010 tweet by Jeremy Corbyn where he appeared to express support for it (so far he doesn’t seem to have commented again so let’s be generous: maybe he’s re-evaluated in the last five years). A few days ago The Express newspaper printed an article pointing out that in these times of austerity, the NHS is spending £5 million a year on ineffective homeopathic remedies, and then, of course, there was that really weird incident earlier in the month where a number of delegates apparently fell ill with hallucinations and cramps during a homeopathy conference in Germany (if an ‘LSD-type drug’ was involved, we can be certain of one thing: it wasn’t homeopathic).

I’m not going to go into the ‘science’ of homeopathy again, because I’ve done that before (seriously, if you don’t know what it is, follow that link back there). And besides, I’m starting to think the science angle is a bit (haha) pointless. Not because it’s wrong, but because it boils down to an un-winnable argument that goes something like this:

“Homeopathy can’t work because…. dilutions…. molecules… there’s nothing in it…. (etc)”
“AHHH but there are things science doesn’t understand… water memory… quantum (etc)”
“Ok, but many, many controlled trials have shown it doesn’t work.
“Those trials are all carried out by the Big Pharma, I don’t trust them.”
“Well, actually, not all of them….
“You can’t test homeopathy in the lab. It doesn’t work like that.”
“But it should, shouldn’t it? If it works? Legitimate pharmaceuticals have to pass those tests.”
“The tests are flawed.The whole peer-review system is corrupt.”
“Well, it may have a few problems, yes, but it’s the best thing we have right now.”
“Anyway, homeopathy cured by my brother’s milkman’s aunt’s dog’s arthritis.”
“Anecdotes really aren’t evidence.”
“Look, it doesn’t matter, I believe it works.”

And there we have it. You can’t get past that, at least, not with science. People that believe (and some of them are, worryingly, scientists and doctors) just believe. You can show them with evidence all day: they’ll tell you the science is wrong, or lacking in some way. Adding more science to that doesn’t help, it’s just – from the believer’s point of view – more science which is still wrong, or still lacking.

So recently I’ve taken another tack. I say, look for the money.

James Randi first issued his challenge in 1964.

In 1964 a stage magician and skeptic called James Randi issued a challenge, and it was this: anyone successfully demonstrating a supernatural or paranormal ability under agreed-upon scientific testing criteria would be paid a $1000 prize. Later it went up to $10,000, then $100,000 and eventually $1 million.

Since the challenge was first created by Randi over half a century ago, about a thousand people have applied, but no one has been successful. No one.

What does this have to do with homeopathy? Well, quite a lot. Because Randi has stated that homeopathy qualifies. In other words, anyone who can prove it works – under testing criteria agreed between the James Randi Educational Foundation (JREF) and the claimant – would win the $1 million. It doesn’t have to be some sort of ‘Big Pharma’ approved trial, it just has to be a trial that both JREF and the claimant agree, between them, is valid.

Big Homeopathy (well, they do it, why not us?) is unquestionably a million dollar business, perhaps the prize has never been claimed because ‘they’ don’t care about a piddly million dollars? But what about all the small-time homeopaths practising around the country? What about academics who continue to maintain that it works? Surely not all of these people are millionaires? $1 million has got to be worth having, hasn’t it?

I repeat. The prize never been claimed (despite at least one high-profile attempt).

James Randi, who is, at time of writing, 87 years old, has now retired. But fear not, JREF have said that they will continue the million dollar challengeas a means for educating the public about paranormal claims”.

Boots.com are selling homeopathic ‘remedies’ right now.

So this is what I say: if you believe homeopathy works, if you think you have convincing evidence that it works, go and claim the money. Then come back to me and we’ll talk. I promise to listen.

If you find yourself talking to proponent of homeopathy, suggest this to them, see what they say. One million dollars has got to be worth a bit of effort, surely?

Call me an old cynic, but I suspect at least some of these people know it doesn’t work, but selling pills that are made of nothing more than sugar, water and fancy packaging for over £5 a pop, or consultations at £30-£125 an hour, is making plenty of money anyway. Why mess with a good thing?

Forget belief, or even science. Look for the money.

Please don’t eat apricot kernels

Capture

Apricot kernels do not cure cancer.

I’ll admit, I’m no huge fan of ‘alternative medicine’, particularly the ones which have been thoroughly tested and shown over and over again to be entirely ineffective (yes homoeopathy, I’m looking at you).

At best these treatments don’t work, and at worst they delay or even stop people getting the effective treatment they need. In fact, there’s an even worse possibility: they stop people from people from giving their children the treatments they need.

Ok, if you’re old enough to make decisions for yourself, and you’ve tried conventional medicine and it hasn’t worked terribly well for your particular problem, and you’ve found that, say, acupuncture somehow does make your chronic back pain a bit better, even if it is just placebo effect, then hey, it’s your money (just please don’t recommend it to anyone else who hasn’t checked out all their other options first, ok?) Also, please, please read this fantastic article which explains clearly what cancer is and what, crucially, it isn’t.

But there has surely has to be a special corner of hell reserved for people who peddle so called ‘cancer-cures’.

Medicine has moved on a lot in the last few decades. Advanced screening techniques and treatments mean that many cancers are no longer the death sentence they once were. 50% of people (in England and Wales) now survive cancer for ten years or more, which is double the figure 40 years ago. But it’s easy for a well person to say ‘cancer treatments’. They are not always quite so easy to get through. Cancer treatments – namely surgery, radiotherapy and chemotherapy – can be brutal and frequently come with a raft of unpleasant side-effects, particularly chemotherapy.

There are some people who decide that the cure is worse than the disease and personally, I think that’s their choice to make. They should have the right to make that choice, so long as it’s well-informed.

So long as it’s well-informed.

But there are people out there who are making money from desperate cancer sufferers. They sell them ineffective treatments, discourage them (directly or indirectly) from seeking or accepting the treatment they really need, and sometimes even encourage those people to use toxic substances that are likely to actually cause even more harm.

People like Roger Shelley, owner and director of The Vitamin Service Ltd. Who has just been given a six-month suspended prison sentence and his company fined £10,000 for selling potentially toxic ‘vitamins’ he claimed could cure and prevent cancer.

512px-Amygdalin_structure.svg

Amygdalin. It’s not a vitamin.

In particular, he was selling apricot kernels, which he claimed contained a ‘vitamin’ called B17. There is no such vitamin. The chemical in question is something called amygdalin (sometimes also referred to as laetrile, although they are not quite the same thing). See the picture of it? See that CN group down at the bottom? That’s a nitrile group. Potassium cyanide, the poison so beloved of crime writers, has the formula KCN, which is a compound made up of K+ and CN ions. It’s the cyanide ions, CN, that do the damage, by interfering catastrophically with the way the body uses oxygen. Now, nitriles (like amygdalin) don’t usually give up their cyanide ions easily and so aren’t, generally, anywhere near as toxic as compounds like potassium cyanide.

Unfortunately one of the enzymes in your small intestine helps to speed up the breakdown of amygdalin. Eating apricot kernels can cause severe toxicity and death due to cyanide poisoning. Yes, severe toxicity and death. Eating apricot kernels can kill you.

Before I cause mass panic I should probably point out that if you accidentally swallow one on a summer picnic, do not fear. It takes more than one to do any damage. The Food Standards Agency says it’s safe to eat one apricot kernel a day (they’re not saying you should, mind you).

The Vitamin Service was recommending that adults take 35 kernels every day. That IS enough to do damage. In fact, it’s above the dose that the FSA highlights as causing severe symptoms. In this statement, they site a case (point 15) of a woman who ate 30 apricot kernels and was later found comatose.

Worse, The Vitamin Service were also recommending that children take 10 kernels a day, “to ward off cancer”. For children, who have a smaller body mass than adults, even this smaller dose could be extremely dangerous.

Patients following The Vitamin Service’s regime reported symptoms of dizziness and cogitative problems. Classic symptoms of cyanide poisoning. When they reported these symptoms they were advised to reduce the amount for a few days before increasing it again, because the symptoms were due to ‘toxins’. Indeed they were, a toxic substance in the very products The Vitamin Service were selling.

To add insult to injury, they were charging in the region of £600 for these kernels along with a raft of other supplements they were recommending.

Shelly admitted to misleading customers and failing to warn them of the risks of B17. He has been given a six month suspended prison sentence, and his company is no longer selling apricot kernels as a cancer treatment. Which you’d think would be a good thing. Problem solved, no?

Just Google “B17 cancer” or “apricot kernels”. There are dozens of sites out there promoting it as a cancer treatment, and many still selling products. I won’t link to them here, I don’t want to give them the traffic. But it’s frightening. Please don’t believe these people. Please listen to your doctors, the real ones, the ones who have studied for years to learn everything they can about medicines and illnesses, and who have sworn an oath to “do no harm”.

There isn’t an easy, painless, magical cure for the cancer that the pharmaceutical industry is hiding from us for some reason. We all wish there was, but there isn’t. Cancer is horrible, but a lot of the time these days it’s beatable with the right treatments. And for those, you need a qualified doctor.

This story was covered in detail on The One Show on BBC One, on Monday 4th February 2015. You can watch the clip here: start at about 4:30 minutes.

There is also an excellent, very easy to follow, summary of the use of laetrile on the charity Cancer Research UK’s website. Read it here.

Finally, once again, if you’re in the unfortunate position of having been diagnosed with cancer, please, please read this excellent article. It really does help to understand the importance of targeted treatment.

Update 8th June 2015

When I wrote this post I focused on the eating of actual apricot kernels, and Roger Shelley’s conviction for selling them. It is worth pointing out that although apricot kernels definitely contain amygdalin, it’s impossible to be certain exactly how much any one kernel contains. This is always a risk with any natural product like this.

This means there is a big, huge, difference between eating apricot kernels – even a known number of them – and being exposed to a small amount of amygdalin in a controlled manner, say as part of a cancer treatment trial. In the first situation you have no idea how much of the chemical you’re being exposed to, and no one is monitoring you to check for ill effects (which you might, or might not, be aware of). It is true that otherwise toxic compounds are utilised in chemotherapy. Arsenic trioxide is used to treat a particular kind of leukaemia for example, but this doesn’t mean swallowing a teaspoon of it every day ‘just in case’ would be in any way sensible or safe.

In 2010 there was a Cochrane review of all the work previously done on amygdalin and laetrile. It reported that there was no clinical data to support the use of these substances to treat cancer, that the risk benefit of using these substances was unanimously negative (the risk of severe poisoning far outweighed any possible benefit), and recommended that no further clinical research into laetrile or amygdalin be conducted on ethical grounds.

However, since I wrote this post I have been made aware that some research is still ongoing. Well, science is about finding answers after all. For example, both of the following papers have been published since the Cochrane review:

Notice that these papers are about the specific chemical amygdalin, rather than apricot kernels. Note also that the second paper contains the words in vitro, which means outside of living organisms. In a test tube in a lab basically. This might be an interesting starting point, but it doesn’t necessarily mean that the same effect can be reproduced in living organisms which have inconvenient things like a digestive system to work around. Also, bear in mind that effective cancer treatments are highly targeted. Tossing unknown amounts of a substance into the general vicinity of a tumour and hoping it’ll have the effect you want is like throwing a bucket of paint at a piece of fine china and expecting to see pretty decorations appear.

Digestion is a particularly thorny problem with this substance: in the first paper I mentioned above (which is a review of the work done to date, rather than new research) the authors specifically point out that amygdalin is a lot more toxic when it’s taken orally than when it’s given intravenously (injected). The reason is that, as I mentioned in my original post, it’s broken down by enzymes in your small intestine. You’re going to have a hard time injecting apricot kernels; you pretty much have to eat them. Which is risky.

Also, while the authors do provide a lot of examples of the therapeutic benefits of amygdalin, they also point out that the (apparent) “antitumor mechanism of amygdalin is not completely clear”, that “clinical trials and large retrospective studies showed that [it] had no stable antitumor effect” and that adverse reactions have been reported, particularly following large doses.

So, while this compound might be a subject for further research, I stand by my original point. Don’t eat apricot kernels.

Further update, 20th August 2015

I’ve recently been made aware of a someone called Dr Philip Binzel and, what appears to be, a rather famous book called “Alive and Well“. In this book, Dr Binzel describes his treatment of cancer patients using dietary changes and supplements, including laetrile. I can find remarkably little information about Dr Binzel and his credentials beyond what’s described in this book. However, it is a matter of public record that he died on June 6, 2003. So take any source discussing his work in the present tense with a large pinch of salt.

Another recent post on this blog which may be of interest addresses this common complaint, “no one wants to research that; they can’t make any money from it!
