'''Cocaine''' is the most potent stimulant of natural origin. It is extracted from the leaves of the coca plant (Erythroxylum coca), which is indigenous to the Andean highlands of South America. Natives in this region chew or brew coca leaves into a tea for refreshment and to relieve fatigue, similar to the customs of chewing tobacco and drinking tea or coffee. Pure cocaine was first isolated in the 1880s and used as a local anesthetic in eye surgery. It was particularly useful in surgery of the nose and throat because of its ability to provide anesthesia, as well as to constrict blood vessels and limit bleeding. Many of the therapeutic applications of raw, "natural" Cocaine are now obsolete due to the development of safer drugs, either synthesized products from the natural coca extract or man-made using some of the natural products chemical components. | '''Cocaine''' is the most potent stimulant of natural origin.
