Medical history is full of strange practices and beliefs. As scientific principles have become the framework for determining what works (and what doesn’t) in medicine, we’ve seen a steady progression towards more science-based, evidence-based care. Yet some unscientific practices still exist, even when we know they don’t work. It might surprise you to learn that some people believe sugar pills can prevent and heal disease. This belief system, called homeopathy, is a multi-billion dollar industry worldwide, and it’s growing. While there is no convincing evidence to demonstrate that homeopathic treatments are more effective than a placebo, many consumers and even some health professionals accept homeopathy as a legitimate health treatment, and its providers as legitimate health professionals.
Responding to the perceived consumer demand for these products, government regulators have had a difficult decision to make: They could ignore homeopathy as a health practice, treating it like we might think of astrology: firmly outside of medicine, and for entertainment purposes only. Or they could choose some form of regulation, targeting the providers (homeopaths) or the product (homeopathy), possibly with the goal of managing its use, or perhaps limiting harms to consumers. The risk of regulating nonsense is the perceived legitimacy that recognition and regulation implies. Regrettably, regulation in many countries has had that exact effect. What’s worse, regulation often seems to have prioritized the commercial interests of homeopaths (and manufacturers) over the public interest, leaving consumers with little understanding that homeopathy lacks any scientific credibility.
Given the lack of scientific credibility and the evidence it offers no medical benefit, homeopathy has attracted increasing criticism from health professionals, scientists, and science journalists over the years. This advocacy appears to be having an effect. Regular readers at the Science-Based Medicine blog will recall several posts over the past few weeks, describing the possibility of new regulation of homeopathy by the US Food and Drug Administration (FDA). And just recently, Health Canada announced two important changes to its homeopathy regulation, which may signal a new direction that prioritizes the consumer interest and public health. Are we witnessing the beginning of more sensible regulation of this prescientific practice? Continue reading
