Dr. Weil has been on a decades-long campaign to convince the medical establishment that the mind-body connection is real, and that many alternative forms of healing should be combined with conventional medicine... especially in treating diabetes, depression, and many other epidemic "lifestyle" diseases. He describes here how he developed his ideas, on a path that included Harvard Medical School and a career as an ethnobotanist, studying psychotropic drugs and traditional healing in the Amazon. He also talks about establishing the Center for Integrative Medicine, the first of its kind (there are now similar programs at the most prestigious government and academic medical institutions in the country). And he revels in seeing his approach to healing finally gain traction, after years of being dismissed as a radical by the mainstream medical world.
