Calea zacatechichi is a plant used by the Chiapas and Chontal Indians of Mexico to obtain divinatory messages during dreaming. The Chontal Indians, who believe in visions seen in dreams, take tea of Calea zacatechichi with crushed dried leaves (tastes disgusting) or smoke cigarettes from the leaves before going to sleep. The Chontal Shaman call it "thepelakano" or leaves of god.
The tea tastes utterly vile (probably the nastiest tasting tea in the world), however, it is said to be not unpleasant to smoke and produces a uniquie high.
