World Homeopathy Awareness Week – Raising Awareness that Homeopathy is Bulldust!

Well, this week is rather special – it’s World Homeopathy Awareness Week!

First, a very brief primer on homeopathy. Homeopathy was founded in 1796 by Samuel Hahnemann, based on his postulation that “like cures like” – for example, a small amount of a stimulant, such as caffeine, is purported to help with sleep troubles. Homeopathic preparations are produced by “dynamisation” or “potentisation”, in which active ingredients are diluted with alcohol or distilled water, then “succussed” (a form of ritualistic vigorous shaking). The dilution process is repeated until the likelihood of a single molecule of the original ingredient being present in a bottle of homeopathic “remedy” is as close as can be to zero.

Homeopathic remedies are sold as liquids or sugar pills and can be found in health food stores, online shops and to my great disappointment, in pharmacies in Australia. Homeopathy is at times confused with herbalism, as it is included within the scope of “natural medicine”, thus it is worth noting that while herbal remedies contain active ingredients, homeopathic remedies contain no detectable trace of such. For more information, visit the 10:23 Campaign’s page, “What is Homeopathy?” 

 

Beginning on the 10th of April each year,coinciding with the birthday of Hahnemann, World Homeopathy Awareness Week (WHAW) has been established by the World Homeopathy Awareness Organization to coordinate global promotion of homeopathy by those who practice and advocate it. Simultaneously, WHAW has been embraced by critics of homeopathy as a fine time to raise awareness of the lack of plausibility behind the mechanisms used to create homeopathic “remedies”, and the lack of evidence that homeopathy has any physiological effect beyond that of a placebo.

This year, WHAW related discussion kicked off a couple of days early, as Australia’s National Health and Medical Research Council released a draft of their information paper, “Evidence on the effectiveness of homeopathy for treating health conditions“. The NHMRC is accepting feedback on this paper until May 26th, so if you wish to provide them with any feedback for consideration, details on doing so are available via the above link.

Admittedly, when I first heard that the NHMRC were conducting a review on homeopathy studies, I was flummoxed – I was familiar with the findings on homeopathy already, and it seemed akin to reviewing findings on whether the sky was blue, or whether water was… wet. However, more public awareness on homeopathy – and the findings that no credible evidence supports its efficacy – has been a great prompt for the media to get on board and for public discussion of homeopathy to increase.

In short, people are still investing their money and hope in products and treatments which have no plausible mechanism of action beyond a placebo. Pharmacies are still selling homeopathic products, in what I consider to be a terribly unethical case of lending false credibility. A small but important minority of general practitioners are referring their patients to homeopaths and naturopaths (some of whom include homeopathy in their practice). There are people who, heart-breakingly, eschew evidence based medicine in favour of homeopathy – as was seen in the tragic case of Penelope Dingle. As such, I believe that it is worth getting the word out, loud and clear, that homeopathy is a sham.

 

I’ve spotted a few fantastic reads during WHAW this year. First up, Ken Harvey has written a piece on The Drum titled “Homeopathy – We Can’t Have it Both Ways“, in which he discusses the fact that, while the NHMRC paper condemns homeopathy, other authorities still give it legitimacy, by accrediting the study of homeopathy, including it in health insurance plans and allowing it to be sold in pharmacies.

From the Good Thinking Society, here is a wonderful page on Homeopathy Awareness Week, with a list of twelve quick facts on homeopathy. The project director, Michael Marshall, explains the importance of the site and of awareness of homeopathy in his Guardian piece, “Homeopathy Awareness Can Make The World A Happier and Healthier Place“.

This week’s episode of The Skeptic Zone Podcast (permalink) has more information on homeopathy than molecules of active ingredients in a homeopathic dilution, and includes my first attempt at a podcast report (replete with awful jokes, such as the one I’ve just made), in which I cover a minor skeptical activism success on the Better Health Channel’s promotion of WHAW. After an impromptu letter writing and social media campaign last week, and in light of the NHMRC draft report on homeopathy, the Better Health Channel made the commendable decision to remove WHAW from their events calendar. If you’re not already a regular Skeptic Zone listener, I encourage you to give it a go this week – despite my cheesy lines, the show is great.

Speaking of humour, I’d like to provide two more links on which to end this post. They’re not to be taken seriously, but sometimes laughter is… the best medicine. (Sorry – I’ll see myself out).
