Next week, I am interviewing Harriet Hall, M.D. on my Internal Fighting Arts podcast. I have interviewed a Qigong "Master," and I have had one guest who claimed that the elderly students studying tai chi and qigong with him have all had a big change -- their hair color turned from grey to black. Every one of them.

I studied acupuncture for two years. I have practiced qigong for 28 years. But I am skeptical of the claims they make for healing illnesses.

Dr. Hall is known as the "SkepDoc." She is a retired family physician and Air Force surgeon who now writes about pseudoscience for publications such as Skeptic, the Skeptical Inquirer, and the Science-Based Medicine blog.

If you believe in acupuncture, or if you don't believe in it, you should watch Dr. Hall discuss why it is rejected by science. This is the third segment in a 10-part video series on Science-Based Medicine.
