Zacatechichi

Calea ternifolia (synonym Calea zacatechichi) is a flowering plant in the aster family, native to Mexico and Central America. Its English names include bitter-grass, Mexican calea and dream herb. In Mexico it is a herbal remedy for dysentery and fever. The Zoque Popoluca call it tam huñi, "bitter gum", and treat diarrhoea and asthma with it, and the Mixe call it poop taam ujts and use it for stomachache and fever. The Chontal of Oaxaca reportedly use it, as thle-pela-kano, in divination. Isolated reports describe smoking it, drinking it as tea, or placing it under a pillow to induce divinatory or lucid dreams, because it is an oneirogen. The name zacatechichi comes from Nahuatl zacatl chichic, "bitter grass". Its effects are thought to come from caleicine.
