"In The Encyclopedia of Psychoactive Plants Christian Ratsch details the botany history, distribution, cultivation, and preparation and dosage of more than 400 psychoactive plants. He discusses their ritual and medicinal usage, cultural artifacts made from these plants, and works of art that either represent or have been inspired by them." "The text is illustrated with 670 black-and-white illustrations and 800 color photographs - many of which come from the author's extensive fieldwork conducted around the world. They show the people, ceremonies, and art related to the ritual use of the world's sacred psychoactives."--BOOK JACKET
