For years Chris Kilham, The Medicine Hunter, has told us about all his far off adventures and all the best natural remedies for what ails you. He’s written a new book called The Ayahuasca Test Pilots Handbook: The Essential Guide to Ayahuasca Journeying, which is all about the unusual plant-based treatment, providing a practical guide to ayahuasca use, aiding seekers in making right—and safe—decisions about where to go, who to drink with, and what to expect.
