Ah, me. Homeopathy<\/a>.<\/p>\n

* Sigh *<\/strong><\/p>\n

Like most scientists who write about alternative medicine and pseudoscience, I am heartily sick of writing about homeopathy. After all, how many \u00a0times can you explain all the reasons why it is nonsense? The delusions (dilutions?) of its practitioners and disciples seem un-dentable. Of course, as one is often reminded on the internet, once people have accepted something on faith, it is hard to change their mind with mere facts. As a result of this, \u00a0most of the time all I can manage to rouse myself for, even in the face of the truly profoundly homeopathological (see e.g. here<\/a>, or here<\/a>, or here<\/a> for examples) , is a bit of humorous derision<\/a>.<\/p>\n

However, if you have the chance, however small, to do something about the tide of homeopathic nonsense, you probably should.<\/p>\n

Which is why I have just signed this petition about homeopathy<\/a>, started by Sense About Science<\/a>, to pressure the UK medicines licencing agency the MHRA \u00a0to mandate proper (as in “factually accurate and non-misleading”<\/span>) \u00a0information on the homeopathic medicines sold in chemists (pharmacies) in the UK.<\/p>\n

Which reminded me that some four and a bit years ago, before the legislation allowing the current misleading labelling (see below for details of why it is misleading) \u00a0to go forward, I had written an editorial about it for Physiology News<\/em> (original PDF version of the editorial here<\/a>, and PDF of full issue here<\/a>). Which is reproduced below. [Apologies for the slightly sonorous tone. Learned society magazine, and all that.]<\/p>\n

Now, one thing that you may note in the editorial is that all the learned scientific societies also thought the labelling changes – allowing the packaging to make specific claims about what the particular homeopathic medicine could “treat”<\/span> – were a joke.<\/p>\n

Not that\u00a0the last Government was listening.<\/p>\n

Now, while I fear the present UK Government listens even less to scientists than the last one did, one can always hope. And in the meantime, one can at least have a go at shaming the MHRA.<\/p>\n

So please go and sign up<\/a>. <\/strong><\/p>\n

[Note: I have added hotlinks to the editorial, and changed one or two words and some pagination – which in the original version was dictated by space considerations! – but otherwise it stands as written in Oct 2006.]<\/p>\n

Homeopathic “Mumbo-Jumbo”<\/strong><\/p>\n

Many scientists these days have at least the odd moment when they feel that their view of the world is under threat from a tide of what the\u00a0journalist Francis Wheen, in his best-selling book<\/a>, termed \u2018mumbo-jumbo\u2019<\/span>.<\/p>\n

For scientists, \u2018mumbo-jumbo\u2019 manifests itself in the rejection of scientific understanding of how the physical world works in favour of\u00a0mystical beliefs derived from a range of sources.<\/p>\n

The examples are too numerous to list, but as the debate swirls it occasionally coalesces around particular issues. Recent flash-points\u00a0are the challenge to evolutionary theory from so-called \u2018<\/span>Intelligent Design\u2019<\/span> (statement from the Royal Society here<\/a>), and the question of whether complementary and\u00a0alternative medicine has any scientific basis.<\/p>\n

Homeopathy has recently taken centre stage in this latter debate. In May 2006 \u00a0an open letter signed by 12 senior doctors and scientists<\/a> (including several Physiological Society Members) urged that alternative therapies unsupported by evidence of efficacy should not be used in the NHS. Later, the demonstration that homeopathic pharmacies advised homeopathic formulations, which have no antimalarial action,\u00a0as malaria prophylaxis garnered national media attention<\/a>.<\/p>\n

Following the homeopathic malaria remedy media expos\u00e9, it might be thought that the scientific absurdity of homeopathy had been clearly demonstrated. Imagine, therefore, the surprise of many scientists and doctors when the Medicines and Healthcare Products Regulatory Agency (MHRA), the body charged with controlling the safety of medicines in the UK, decided to allow homeopathic remedies to\u00a0be sold with packaging featuring \u2013 for the first time in 30 years \u2013 claims about what the remedy purports to treat<\/a>.<\/p>\n

Previously a homeopathic remedy in a high street chemist would have been labelled \u20186c dilution of Gelsemium sempervirens<\/span><\/em>\u2019<\/span>, or something similarly obscure. It can now be sold, quite legally, as \u2018NoCold-Max cold and flu remedy \u2026 homeopathic\u2019<\/span>.<\/strong><\/p>\n

And as the web site of the European Council for Classical Homeopathy<\/a> puts it:<\/p>\n

\u2018To make such a claim, the manufacturers need only show that the product has been used to treat those particular conditions within the homeopathic industry.\u2019<\/span><\/p>\n

No scientific basis. No clinical trials. No evidence of effectiveness.<\/p>\n

The homeopaths, and the companies that produce over-the-counter homeopathic remedies, are understandably delighted.<\/p>\n

Well, you might say, so what? The placebo effect is not new, and a fool and his\/her money are soon parted. Most scientists would agree that the labelling is a joke, but in a world awash with ridiculous claims, why get worked up?<\/p>\n

Well, firstly, perhaps, because the MHRA, acting on our behalf, is supposed to care \u2013 their web site<\/a> states they \u2018enhance and\u00a0safeguard the health of the public by ensuring that medicines and medical devices work, and are acceptably safe.\u2019<\/span> How they reconcile the first part of this statement with the change in the homeopathy rules is not clear.<\/p>\n

Secondly, because \u2013 at the risk of sounding incredibly pompous \u2013 there is a principle at stake, namely that decisions of this kind should\u00a0be made on the basis of scientific and medical evidence and understanding.<\/p>\n

Finally, the MHRA\u2019s decision to allow licencing and sale of homeopathic remedies in this way is likely to be widely interpreted as approval of\u00a0alternative remedies in general. This in turn will foster the perception that they work.<\/p>\n

The Physiological Society, like other scientific societies, has been asked by the campaign group Sense About Science to comment on the\u00a0MHRA decision, and has issued a statement reaffirming its belief in scientific evidence, and decisions based on it.<\/p>\n

———————————————————————
\n\u2018The Physiological Society is concerned with the scientific investigation of how the body works \u2026 It is our view that “alternative medicine” has, with very few exceptions, no scientific foundation, either empirical or\u00a0theoretical. As an extreme example, many homeopathic medicines contain no molecules of their ingredient, so they can have no effect (beyond that of a placebo). To claim otherwise it would be necessary to abandon the entire molecular basis of chemistry. The Society believes that any claim made for a medicine must be based on evidence, and that it is a duty of the regulatory authorities to ensure that this is done.\u2019<\/span><\/p>\n

———————————————————————<\/p>\n

The Physiological Society\u2019s statement is not, note, a blanket dismissal of all the things the public commonly regard as complementary therapies. Physiologists have long studied the effects of exercise upon the body, and the physiological actions of plant-derived substances. Work goes on into the possible physiological basis of acupuncture, or the physiological effects of alterations in diet.<\/p>\n

But scientists want evidence, not anecdotes and hand-waving. If proper science shows real physiological effects, beyond those of a\u00a0placebo compound or sham intervention, and if these can be made to work as a treatment, what you have is a therapy. Rather than being\u00a0a question of \u2018alternative\u2019<\/span> or \u2018mainstream\u2019<\/span>, it is down to what works \u2013 or more precisely, what we can be sure works because it can be shown\u00a0to work in a properly-designed scientific experiment.<\/p>\n

Which highlights something else we should be thinking about \u2013 our failure, as professional scientists, to inform enough of the public about\u00a0what proper controls are, and exactly why some experiments are convincing, and others are not. About what the placebo effect is in\u00a0medical experiments and trials. About what homeopathy actually is \u2013 you would be surprised how many people, including a good few bioscience graduates I have met, think it means \u2018herbal remedies\u2019<\/span> rather than \u2018infinitely dilute nothing\u2019<\/span> \u2013 and why it is scientifically nonsensical.<\/p>\n

None of these is terribly complex to explain, and many of them go to the heart of what science is, and how it is done. In many ways,\u00a0this seems a golden opportunity to use the public interest to put across how science offers a clear way to divide what actually works from what doesn\u2019t.<\/p>\n

As the immortal Richard Feynman<\/a> put it:<\/p>\n

\u2018Science is a way of trying not to fool yourself. The first principle is that you must not fool yourself, and you are the easiest person to fool.\u2019<\/span><\/p>\n

As this issue went to press, The Society\u2019s statement, along with many others, was being passed to interested members of the House of Lords in advance of a debate on the new homeopathy regulations on 26 October. By the time you read this, we should know if it did any\u00a0good. But whatever the result, get polishing your homeopathy-debunking speech.<\/p>\n

And I like to think Feynman would not mind us pinching his lines.<\/p>\n","protected":false},"excerpt":{"rendered":"
