When you hear the term “hypnosis,” what immediately comes to mind? Is it a clock-swinging magician or a comedy hypnosis show? What most people don’t know about hypnotherapy is that it’s actually an accredited science with tremendous healing power.

On today’s episode of The Doctor’s Farmacy, Dr. David Spiegel, the world’s leading researcher and clinician in the field, is here to help us better understand the scientific power of hypnosis.

Dr. David Spiegel is the Willson Professor and Associate Chair of Psychiatry & Behavioral Sciences, Director of the Center on Stress and Health, and Medical Director of the Center for Integrative Medicine at Stanford University School of Medicine, where he has been a member of the academic faculty since 1975, and was Chair of the Stanford University Faculty Senate from 2010-2011. Educated at Harvard and Yale before coming to Stanford, he has written thirteen books, 404 scientific journal articles, and 170 book chapters. He is also the Co-Founder and Chief Scientific Officer of the clinically-backed self-hypnosis app, Reveri.
