Salvia divinorum (also known as diviner's sage or simply salvia) is a psychoactive plant, a member of the sage genus. The plant is grown by the Mazatec indigenous people of the Oaxaca mountains in isolated, moist and secret plots. It has been used by their shamans for centuries for healing during spirit journeys. The active chemical, Salvinorin A (there are also B and C forms), is unique in that it is an agonist of neuroreceptors largely ignored by other known drugs. It is extremely powerful, but controllable.
