In this discussion with D.J. Grothe, Dr. Barrett defines complementary and alternative medicine (CAM), the responsibilities of the consumer of healthcare, whether or not CAM is growing in mainstream healthcare, and the types of people who are susceptible to CAM claims. He also explores various CAM therapies including Therapeutic Touch, Chiropractic, myths about water fluoridization, and how a skeptic might most effectively confront family members who are consumers of complementary and alternative medicine.
