Why we don’t prescribe bark for cancer
My valued colleague, Dr. Antonio Baines, recently invited me to speak for his graduate course in Toxicology. Dr. Baines’ course is one of the most highly-regarded graduate classes at North Carolina Central University for M.S. students in Biology and Pharmaceutical Sciences. Antonio asked that I discuss the pharmacology and toxicology of herbal and non-botanical dietary supplements but pretty much gave me free...

How State Medical Boards Shoot Themselves (and You) in the Foot
This is almost the final entry (for now) in a series of posts about the pitfalls of regulating physicians who peddle quackery.† In previous entries we’ve seen how quacks have portrayed an illegal and pseudoscientific treatment, intravenous hydrogen peroxide, as legitimate; how a physician who practiced that and other dubious methods eluded definitive regulatory sanctions for years; examples of quacks banding together to...
Functional Medicine – New Kid on the Block
What is functional medicine? An indecipherable babble and descriptive word salad.

Knowledge Versus Expertise: The View From Consumer Land
“The internet, in democratizing knowledge, has led a lot of people to believe that it is also possible to democratize expertise.” – SBM Commenter, yeahsurewhatever I’ve spent the last few years of my life in Internet “Consumer Land,” doing what I can to bring accurate health information directly to patients. Of course, I have been surprised by the push-back, and the demand...
Fake Treatments for Fake Illnesses
I wrote previously on NeuroLogica blog about Morgellons disease. Both Peter Lipson and Wallace Sampson have also covered this interesting syndrome here on SBM. Briefly, sufferers of this dubious syndrome believe they have foreign material exuding from their skin, causing chronic itching and sores. The evidence suggests that in truth they suffer from something akin to delusional parasitosis – the false belief...
Another Useless NCCAM-Funded Study
Sometimes I read an article in a medical journal that makes me say, “Well, duh! I could have told you that without a study.” Sometimes I read collected data that make me ask, “So what?” Sometimes I read an article that makes me wonder what kind of pogo stick they used to jump from their data to their conclusions. Sometimes I read...
Do physicians really believe in placebos?
In a previous post, I argued that placebo is an artifact of certain clinical interactions, rather than a treatment that we can exploit. Apparently, there are a whole lot of doctors out there who don’t agree with me. Or are there? A recent study published in the British Medical Journal is getting a lot of enk (e-ink) in the blogosphere. As a...
Placebos in the news again
Towards the end of last week, I was contemplating what I would be writing about for Monday. No topic had quite floated my boat, but I hated to dip into the archive of topics I’ve written about before to update a post. After all, I like to be topical whenever possible. Then what to my wondering eyes should appear (yes, I know...
Is There a Placebo Effect for Animals?
One of the occasional arguments used in support of “alternative” approaches to human medicine is the observation that since “alternative” medicine is used (with anecdotal success) in animals, and animals don’t know anything about the treatment that they’re getting, then they must work a priori. Of course, the fallacy of such an observation is pretty obvious to anyone with a logical/skeptical frame...
When Further Research Is NOT Warranted: The “Wisdom of Crowds” Fallacy
Most scientific research studies have at least one thing in common: the conclusion section ends with, “further research is warranted.” I’d say it’s about as common as the “talk to your doctor” disclaimer in TV ads for pharmaceutical products. And in a way, they both serve the same purpose. They’re a “CYA” move. What does “further research is warranted” mean in plain...
