Supplements: Still popular despite little evidence they’re useful
As healthcare systems struggle to cope with growing and aging populations, there is renewed interest in eliminating wasteful, and possibly harmful, care. The Choosing Wisely campaign suggests that up to 30% of health care services may be unnecessary. Driven by the medical profession itself, Choosing Wisely is challenging both patients and health care providers to have an honest dialogue about the appropriateness...
Corydalis: An Herbal Medicine for Pain, with Some Thoughts on Drug Development
Ever since William Withering published his classic treatise on Foxglove in 1775, science has been testing herbal medicines and trying to establish a scientific basis for the ones that work. As many as half of today’s prescription drugs were derived from plants. A new study published in Current Biology by Zhang et al. has identified a compound in a traditional herbal remedy...
Update on CCSVI and Multiple Sclerosis
In 2009 CCSVI was proposed by Italian vascular surgeon, Dr. Paolo Zamboni – that multiple sclerosis (MS) is caused by chronic blockage of the veins that drain the brain. Since that time we have seen the evolution of a medical pseudoscience. It has been a fascinating case study in how science sorts out what works and what doesn’t, and how patients, believers,...
An Update on FDA Concerns Over Homeopathic Teething Products
Steven Novella recently wrote a post discussing an FDA warning against the use of homeopathic teething products over safety concerns related to the possibility of toxic amounts of belladonna. He goes into the hypocrisy of the FDA regulation of homeopathic products, a topic covered numerous times here on Science-Based Medicine, as well as the misleading initial response from Hyland’s, producers of the...
Natural Health Products: Loosely regulated, little evidence of benefit, and an industry intent on preserving the status quo
This week’s post will revisit a topic I recently covered, but it’s time-sensitive and needs your input. Health Canada, the Canadian equivalent to the US Food and Drugs Administration, is considering revisions to the way in which it regulates dietary supplements, which are called “natural health products” in Canada. It is rare that a regulator acknowledges that a regulatory system isn’t working,...

When should I get the influenza vaccine?
I was asked this question by one of my infection control practitioners. We started offering the flu vaccine the first week of October and some have delayed getting the shot for fear that immunity will not last the season. She pointed me to this NPR article, “Yes, It Is Possible To Get Your Flu Shot Too Soon,” as driving the fear of...
Researching the Magic of Homeopathy
A Canadian academic, Dr. Mark Loeb, who is a respected infectious disease researcher who knows how to conduct high quality research, wants to study homeopathic nosodes. Nosodes are essentially homeopathic vaccines. Tim Caulfield, a Canadian professor of health law and policy, thinks the study is misguided and unethical. The two are having a respectful public debate about the risks and merits of...
In which we are accused of “polarization-based medicine”
A little over a month ago, I wrote about how proponents of “complementary and alternative medicine” (CAM), now more frequently called “integrative medicine,” go to great lengths to claim nonpharmacological treatments for, well, just about anything as somehow being CAM or “integrative.” The example I used was a systematic review article published by several of the bigwigs at that government font of...
Plavinol and Other Natural Remedies for Diabetes: “Condimentary Medicine”?
We don’t yet have a cure for diabetes, but we have insulin; it controls the disease and allows Type 1 diabetics to lead a relatively normal life instead of suffering and quickly dying as they all did in the pre-insulin era. We know to counsel Type 2 diabetics about weight loss, diet, and exercise; and when those measures are not enough, we...
