Andrew Thomas Weil (June 8, 1942) is an American medical doctor and naturopath, and a teacher and writer on holistic health.
He is founder, professor, and director of the Arizona Center for Integrative Medicine at the University of Arizona. He received both his medical degree and his undergraduate degree in biology from Harvard University and established the field of integrative medicine which aims to combine alternative and conventional medicine. Weil says that patients should take the Western medicine prescribed by the doctor, and then incorporate alternative therapies such as omega-3 fatty acids, vitamin D, and herbal remedies, meditation and other “spiritual” strategies. Some mainstream medical professionals have criticized Weil for rejecting aspects of evidence-based medicine and promoting unverified beliefs.
Weil appeared on the cover of Time Magazine in 1997 and again in 2005. He has written many books and a total of 10 million copies have been sold. These books include Spontaneous Healing, 8 Weeks to Optimum Health, and Healthy Aging. He has been a frequent guest on the Larry King Live, Oprah, and the Today Show.
