In this podcast, Dr. Rankin speaks with Sounds True founder, Tami Simon, about her new book, Sacred Medicine: A Doctor's Quest to Unravel the Mysteries of Healing. Their conversation explores: the placebo effect and the mega-placebo effect; the scientific method and some assumptions we should question; the relationship between trauma, the nervous system, and healing; connectivity and co-regulation; developmental trauma, or what Mark Epstein calls "the trauma of everyday life"; the concept of spiritual bypassing; chronic inflammation as a root cause of many diseases; the paradoxes of healing; our four "intelligences"—mental, somatic, intuitive, and emotional—and what to do when they "disagree"; Internal Family Systems (IFS) therapy and working with the polarized parts within ourselves; healing the collective; and more.
