VANCOUVER—A retired doctor who spent years treating drug addiction says he has seen the healing powers of a psychedelic plant that a Vancouver Island man was studying in Peru before he was killed by a mob that blamed him for a shaman’s death.
Dr. Gabor Maté said ayahuasca grows in the jungle and is brewed with other plants into a thick concoction people drink at ceremonies in countries such as Peru, Costa Rica, and Brazil.
