Calea Zacatechichi

Calea zacatechichi, also known as Dream Herb, Leaf of God, and Bitter Grass, is a plant used by the indigenous Chontal of the Mexican state of Oaxaca for oneiromancy (a form of divination based on dreams.) The plant naturally occurs from southern Mexico to northern Costa Rica. There are currently two reported varieties, one being extremely bitter and the other non-bitter. It is also employed by the Chontal people as a medicinal herb against gastrointestinal disorders, and is used as an appetizer, cathartic anti-dysentery remedy, and as a fever-reducing agent.

The correct Latin name is Calea ternifolia Kunth, with Calea zacatechichi Schltdl. being a synonym. The name zacatechichi retains usage as a local or common name.
