What Is Traditional Chinese Medicine?
Traditional Chinese Medicine is not actual medicine, and should not be treated as such. It has more in common with Galen's theory of the four humors than anything a doctor would recognize today.
An Owner’s Manual for the Heart
In writing about science-based medicine, we give a lot of attention to medicine that is not based on good science. We use bad examples to show why science is important and how it is frequently misapplied, misinterpreted, misreported, or even wholly rejected. It’s a pleasure, for a change, to write about a straightforward example of the best of science-based medicine in action....
The New England Journal of Medicine Sinks a Bit Lower
I suppose it was bound to happen, but it still rankles. Here is the back cover of last week’s issue of the decreasingly prestigious New England Journal of Medicine: Here’s the front cover: It’s the 200th Anniversary issue, no less. Some might protest that ‘probiotics’—live bacteria of ‘good’ varieties, as far as the gut is concerned—aren’t all that implausible, and that...
The rebranding of CAM as “harnessing the power of placebo”
If there’s one thing I’ve learned over the past seven years or so that I’ve been blogging, first at my other “super secret” (or, more accurately, super “not-so-secret”) blogging location, and then the four years I’ve been blogging here at Science-Based Medicine (SBM), it’s that the vast majority of “alternative medicine,” “complementary and alternative medicine” (CAM), and “integrative medicine” (IM) treatments (or...
Why Do We Really Need Clinical Trials?
A point I make over and over again when talking about new or alternative therapies that are not supported by good clinical trial evidence is that lower-level evidence, such as theoretical justifications, anecdotes, and pre-clinical research like in vitro studies and animal model testing, can only be suggestive, never reliable proof of safety or efficacy. It is necessary to begin evaluating a...
Shilling for traditional Chinese medicine: Nature leaves its readers a lump of coal before Christmas
I’ve subscribed to Nature for many years now, even though I don’t always read it. Nature is one of the oldest and most respected scientific journals around. It’s been around since 1869 and is said to be the world’s most cited journal. What makes Nature unusual these days is that it’s one of the last of the remaining general science journals and...
Hypothyroidism: The facts, the controversies, and the pseudoscience
As glands go, we don’t give the butterfly-shaped thyroid that straddles our trachea too much thought — until it stops working properly. The thyroid is a bit like your home’s thermostat: turn it high, and you’re hyperthyroid: heat intolerant, a high heart rate, and maybe some diarrhea. Turn it down, and you’re hypothyroid: cold, tired, constipated, and possibly even depressed. Both conditions...
Iridology
Iridology claims that it can diagnose diseases through a careful examination of the iris. Unsurprisingly, there is no proof for this, and when tested it fails spectacularly.
A Christmas Card from the SkepDoc
The holiday season is upon us. As a bit of a holiday from science-based writing, I thought I would offer some thoughts inspired by the season and not supported by any scientific evidence. One of my friends refers to Christmas as “The Feast of St. Dyspepsia.” Holidays are indeed an occasion for over-indulging. People change their routine: they have time off work,...
