In Pharmako/Dynamis, Dale Pendell continues his exploration of psychoactive plants begun in Pharmako/Poeia. Pharmacognosy is the study of the composition, production, use, and history of drugs of natural origin. Pendell covers these topics and more in this volume, charting a voyage around the world of plant teachers. Through poetry, chemistry, and a generous sprinkling of arcane lore, Pendell weaves and twists the many threads of tradition into a singularly bewitching brew. Pendell's voyage is a true circumnavigation. It divulges what Gary Snyder called "dangerous knowledge" that is a formidable weapon against "even more dangerous ignorance."
