After a long time of research and reading many books about salvia I have gathered some precious information about history of salvia.
This mystic plant Salvia Divinorum is one of over two thousand varieties of the plant genus Salvia (Sage), and the plant has been used for centuries as a holy visionary and curing medicine by the Mazatec Indians living in Oaxaca, southwestern Mexico.
Salvia Divinorum is a wild plant and you can find them in small mountainous region of Sierra Mazateca in Oaxaca. In addition to its psychoactive use in forecasting ceremonies, the medication has traditionally been used in small amounts as a diuretic and to treat rheumatism and headaches.
Salvia Divinorum’s psychoactive mechanism was not identified until the 1990’s by a team led by Daniel Siebert. It is not a common herb and only grows wild in Sierra Mazateca where it thrives near streams in fertile rift areas that are shaded and moist mountainous regions at an altitude of between 1,000 and 6,000 feet. However, it also grows in parts of coastal California and Hawaii that enjoy coastal fogs and which remain frost-free.
The plant of Salvia Divinorum has square stems that can easily break off and start rooting on the ground through the nodes and internodes. Salvia Divinorum has leaves that are green with a yellow tinge tone and which measure between four and twelve inches long with serrated edges. The whole plant grows to just over three feet in height. It has rarely flowers on it, however, when it does, it produces white flowers about 1.25 inches in circumference that are curved with white hairs held in a bluish-purple calyx. Since its seeds are hardly ever viable, the Salvia Divinorum plant spreads primarily through cloning.
Scientists have therefore concluded the plant is either a Mazatec cultigen, with its partial unproductiveness due to long term cultivation and selection, although the two parent species have not yet been found.
