A preview episode of my upcoming podcast, Plant Medicines Now: Dr. Dan Engle is board certified in psychology and neurology, and has a long history of researching psychedelic plant medicines. On this episode, he explains how doctors are using the Iboga plant to break heroin addiction in a matter of hours, with zero withdrawals. He goes on to express how his own opinion of pharmaceuticals has changed over the course of his career, and how plant medicines excel in areas in which western medicine and psychology fails.
