Kola Nut (Cola) is 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. They are evergreen trees, growing to 20 m tall, with glossy ovoid leaves up to 30 cm long. They also have star shaped fruit. The tree grows up to 60 feet tall (about 18 meters).

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.

Kola nuts are often used to treat whooping cough and asthma. The caffeine present acts as a bronchodilator, expanding the bronchial air passages.

Kola nuts are perhaps best known to Western culture as a flavouring ingredient and the source of caffeine in cola and other similarly flavoured beverages.[citation needed] The "Cola" in Coca Cola itself references the use of the Kola nut.

In the Igbo culture, a man is allowed the liberty of being ambivalent about his faith, but not about the preeminent place of the kolanut in any family gathering or cultural event. Kolanut – Food of the Gods.
