The Toronto Star published a letter from a physician in BC who was critical of my attacks on homeopathy. Below is his letter as well as my response.

As a medical doctor, I use homeopathy on a daily basis to fill in gaps or improve on the conventional therapies I also use in family practice. There is no doubt that homeopathy works – even in children and in skeptical patients that are willing to give it a try (particularly if they have tried everything else without benefit); sometime even in patients’ pets. Sure, good interaction and placebo play a role, just as in any therapeutic encounter, but that does not explain the results I observe.When a group of “top” scientists declare that there is no evidence to support homeopathy, you cannot but wonder at their agenda. In fact, there have been several meta-analyses and governmental assessments that show homeopathy is effective (BMJ 1991, Lancet 1997, Eur J. Clin Pharmacology 2000, Swiss Federal Office for Public Health 2006).
There are numerous positive trials, many of fair to high quality. Medical doctors around the world have accepted homeopathy based on sound evidence and the personal experience that confirms it. In Belgium, for example, 4000 doctors prescribe homeopathic medicines routinely. Homeopathy is inexpensive, convenient, integrates well with conventional medicine, and patient satisfaction and safety are excellent. It is included in the national health schemes of Great Britain, France, Switzerland, Brazil, Mexico, India and many other countries. The recent discovery of nanoparticles in homeopathic ultra-dilutions has undermined the “implausibility argument” or “I can’t understand how it works, therefore it can’t work.” This type of flat-earth thinking is not helpful in promoting better healthcare and has no place in medical practice or research.
The main reason pseudo-scientists become quack-busters and criticize therapies such as homeopathy is fear. Perceived as a threat to their world-view, they use the labels “unscientific” or “implausible” to defend themselves against the barbarians at the gate. It is not really an issue of evidence or science. It’s a subconscious defense mechanism that cannot be overcome, even if the research is piled up to the ceiling. It may be disguised as defending the public, but as Shakespeare says: “The lady doth protest too much.” The potential benefits of homeopathy demand research such as Dr. Heather Boon’s ADHD study at University of Toronto, and we should not let fixed thinkers get in the way of progress in medicine. In fact, the criticism here should be levelled at Ď㽶ĘÓƵ for permitting its Office for Science and Society to exist and Dr. Joe Schwarcz to continue to “interpret science for the public.” Dr. Stephen Malthouse, past president, Canadian Complementary Medical Association, Denman Island, B.C.
MY RESPONSEĚýDr. Stephen Malthouse’s ungracious letter requires a response. “There is no doubt that homeopathy works,” he maintains. That may be his opinion but not that of the vast majority of the scientific community. That point was effectively driven home last week by a report from Australia’ s National Health and Medical Research Council that concluded “there is no good quality evidence to support the claim that homeopathy is effective in treating health conditions.” It was the most damning analysis of homeopathy ever compiled.
Dr. Malthouse trots out the tired old refrain that a discovery of some anomalous property of water undermines the argument that homeopathy is implausible. Nobody has ever maintained that homeopathy is implausible because water cannot have anomalous properties. That is a straw man argument if there ever were one. Homeopathy is implausible because it is based on the precept of ghostly images supposedly imparted to water by sequential dilutions and succusions having a healing effect.
Dr. Malthouse goes on to suggest that “it is not really an issue of evidence or science.” It most assuredly is. The science of homeopathy is non-existent, just like the molecules it is supposedly based upon. And the evidence is in for anyone who cares to look at the 225 well-designed studies that formed the basis of the Australian report. As far as Dr. Malthouse’s boorish remark that the McGill Office for Science and Society should not exist, his letter is a shining example of why there is a continuing need to interpret science for the public in an evidence-based fashion, which is exactly why the Office was established.
