"Salvia divinorum is a perennial herb in the mint family native to certain areas of the Sierra Mazateca region of Oaxaca, Mexico. The plant can grow to over three feet in height, has large green leaves, hollow square stems, and white flowers with purple calyces. The plant can also be grown successfully outside of this region. Salvia divinorum has been used by the Mazatec Indians for its ritual divination and healing. The active constituent of Salvia divinorum has been identified as salvinorin A. Currently, neither Salvia divinorum nor any of its constituents, including salvinorin A, are controlled under the Controlled Substances Act (CSA)."
