Andrew Thomas Weil is an American medical doctor, teacher, and best-selling author on holistic health. He is founder, professor, and director of the Arizona Center for Integrative Medicine at the University of Arizona. He received a B.S. in Biology and a M.D. from Harvard University in 1968. Weil is widely known for establishing the field of integrative medicine, which aims to combine alternative and conventional medicine. Weil suggests that patients take the Western medicine prescribed to them by physicians and then incorporate alternative therapies, such as omega-3 fatty acids, vitamin D, herbal remedies, meditation, as well as other “spiritual” strategies, into their treatment plans. Some mainstream medical professionals, however, have criticized Weil for rejecting aspects of evidence-based medicine and promoting unverified beliefs.
