Harriet Hall, MD also known as The SkepDoc, is a retired family physician who writes about pseudoscience and questionable medical practices. She received her BA and MD from the University of Washington, did her internship in the Air Force (the second female ever to do so),  and was the first female graduate of the Air Force family practice residency at Eglin Air Force Base. During a long career as an Air Force physician, she held various positions from flight surgeon to DBMS (Director of Base Medical Services) and did everything from delivering babies to taking the controls of a B-52. She retired with the rank of Colonel.  In 2008 she published her memoirs, Women Aren't Supposed to Fly.

Conflicts of Interest

When an article is published in a medical journal, the authors must disclose any conflicts of interest. This is important, because even if they think owning stock in the drug company won’t influence their scientific judgment, we know that subtle biases can creep in to somehow affect the findings of studies. It has been shown that studies funded by drug companies are...

Suffer the Children

Some of our readers have complained that we pick on alternative medicine while ignoring the problems in conventional medicine. That criticism is unjustified: we oppose non-science-based medicine wherever we find it. We find it regularly in alternative medicine; we find it less frequently in conventional medicine, but when we do, we speak out.   A new book by Dr. Peter Palmieri is aimed...

The Role of Experience in Science-Based Medicine

Before we had EBM (evidence-based medicine) we had another kind of EBM: experience-based medicine. Mark Crislip has said that the three most dangerous words in medicine are “In my experience.” I agree wholeheartedly. On the other hand, it would be a mistake to discount experience entirely. Dynamite is dangerous too, but when handled with proper safety precautions it can be very useful...

Frequencies and Their Kindred Delusions

The word “frequency” ranks right up there with “quantum” and “energy” as a pseudoscientific buzzword. It is increasingly prevalent in product advertisements and in CAM claims about human biofields and energy medicine. It doesn’t mean what they think it means. I have written about Power Balance products, the wristbands and cards that allegedly improve sports performance through frequencies embedded in a hologram....

Acupuncture Revisited

Believers in acupuncture claim it is supported by plenty of published scientific evidence. Critics disagree. Thousands of acupuncture studies have been done over the last several decades, with conflicting results. Even systematic reviews have disagreed with each other. The time had come to re-visit the entire body of acupuncture research and try to make sense out of it all. The indefatigable CAM...

Herbal Remedies, Street Drugs, and Pharmacology

David Kroll’s recent article on thunder god vine is a great example of what can be learned by using science to study plants identified by herbalists as therapeutic. The herbalists’ arsenal can be a rich source of potential knowledge. But Kroll’s article is also a reminder that blindly trusting herbalists’ recommendations for treatment can be risky. Herbal medicine has always fascinated me....

Spreading the Word

Lest some of our readers imagine that the authors of this blog are mere armchair opinion-spouters and keyboard-tappers for one little blog, I’d like to point out some of the other things we do to spread the word about science and reason. Steven Novella’s new course about medical myths for “The Great Courses” of The Teaching Company is a prime example: more about...

Eating Placentas: Cannibalism, Recycling, or Health Food?

After giving birth, most mammals eat the afterbirth, the placenta. Most humans don’t. Several hypotheses have been suggested as to why placentophagy might have had evolutionary survival value, but are there any actual benefits for modern women? Placentophagy has been recommended for various reasons, from nutritional benefit to preventing postpartum depression to “honoring the placenta.” In other cultures, various rituals surround the...

Questioning the Annual Pelvic Exam

A new article in the Journal of Women’s Health by Westhoff, Jones, and Guiahi asks “Do New Guidelines and Technology Make the Routine Pelvic Examination Obsolete?” The pelvic exam consists of two main components: the insertion of a speculum to visualize the cervix and the bimanual exam where the practitioner inserts two fingers into the vagina and puts the other hand on...

Diet Supplements or Nutritional Supplements: A Ruse by Any Other Name is Still a Ruse

I was surprised to get this e-mail from a reader: Surely, Dr. Hall, the public mania for nutritional supplements is baseless. All the alleged nutrients in supplements are contained in the food we eat. And what governmental agency has oversight responsibility regarding the production of these so-call nutritional supplements? Even if one believes that such pills have value, how can the consumer...
