Khat (Catha edulis) is a plant that is widely grown in the Horn of Africa. People chew the Khat leaves for their stimulating properties. Its tender leaves and early buds are chewed to induce euphoria and stimulation. Khat is an evergreen shrub that can be grown as a bush or small tree. The leaves have a pleasant scent. The taste is astringent with a hint of sweetness. The plant has no seeds and can grow in a variety of climates and soils. The plant contains a vast variety of active compounds, the most important of which are cathinone, cathine, and norephedrine, which can be classified as sympathomimetics of natural origin. These chemicals are amphetamine analogs, and as such, they have amphetamine-like stimulating effects on the neurological system.
