Kola Nut (Cola) is the nut of the kola tree, a genus of trees native to the tropical rainforests of Africa, classified in the family Malvaceae, subfamily Sterculioideae (or treated in the separate family Sterculiaceae). It is related to the South American genus Theobroma, or cocoa. It is an evergreen tree, growing up to 20 m tall (about 60 feet), with glossy ovoid leaves up to 30 cm long and star shaped fruit. The kola nut has a bitter flavor and contains caffeine. It is chewed in many West African cultures, individually or in a group setting. It is often used ceremonially, presented to tribal chiefs or presented to guests. It is preferred among African Muslims, who are forbidden to drink alcohol. Chewing kola nut can ease hunger pangs. Frequent chewing of the kola nut can also lead to stained teeth. Among the urban youth of West Africa, kola nut is becoming less popular.
