Salvia divinorum

Salvia divinorum (sage of the diviners; also called ska maría pastora, seer's sage, yerba de la pastora, magic mint or simply salvia) is a plant species with transient psychoactive properties when its leaves, or extracts made from the leaves, are administered by smoking, chewing, or drinking (as a tea). The leaves contain the potent compound salvinorin A and can induce a dissociative state and hallucinations. Mazatec shamans have a long and continuous tradition of religious use of S. divinorum to facilitate visionary states of consciousness during spiritual healing sessions. Western media panic 2007 centered on reports of legal teenage use of the drug, a suicide, and video sharing of drug use on the internet. S. divinorum is legal in some countries, including the U.S. at the federal level; but over half the states have passed laws criminalizing it. Its native habitat is cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady, moist locations. The plant grows to over a meter high, has hollow square stems like others in the mint family Lamiaceae, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether S. divinorum is a cultigen or a hybrid because native plants reproduce vegetatively and rarely produce viable seed. Because the plant has not been well-studied in high-quality clinical research, little is known about its toxicology, adverse effects, or safety over long-term consumption. Its chief active psychoactive constituent is a structurally unique diterpenoid called salvinorin A, a potent κ-opioid agonist. Although not thoroughly assessed, preliminary research indicates S. divinorum may have low toxicity (high ). Its effects are rapid but short-lived. The genus name, Salvia, was first used by Pliny for a plant that was likely Salvia officinalis (common sage) and is derived from the Latin salvere. The specific epithet, divinorum, was given because of the plant's traditional use in divination. It is often loosely translated as "diviner's sage" or "seer's sage".
