Erythroxylum coca is a small evergreen shrub native to the Andean region of South America. It typically grows between 1 to 3 meters tall and has glossy green leaves. The plant is best known for its leaves, which contain alkaloids, including cocaine, a powerful stimulant. Traditionally, the leaves of Erythroxylum coca have been used by indigenous peoples for centuries for their stimulant effects and to alleviate altitude sickness. The plant plays a significant role in local cultures, where the leaves are often chewed or brewed into tea, providing energy and reducing fatigue.
