* * *or cola nutCaffeine-containing nut of two evergreen trees (Cola acuminata and C. nitida) of the cocoa family (Sterculiaceae), native to tropical Africa and cultivated extensively in the New World tropics.The trees grow to 60 ft (18.3 m) in height and have oblong leathery leaves, yellow flowers, and star-shaped fruit. The nut has been used in medicines and in soft drinks, though American "colas" today instead use synthetic flavorings that mimic its taste. Kola nuts are also used where grown as a medium of exchange or are chewed to diminish sensations of hunger and fatigue, to aid digestion, and to combat intoxication, hangover, and diarrhea.Kola nut (Cola nitida)W.H.

* * *▪ plantcaffeine-containing nut of Cola acuminata and Cola nitida, trees of the cocoa family (Sterculiaceae) native to tropical Africa and cultivated extensively in the American tropics. The evergreen tree grows to 18.3 m (60 feet) and resembles the chestnut. The 5-centimetre- (2-inch-) long brown nut is hand collected and dried in the sun for commercial use, mainly as an ingredient of soft drinks (soft drink) and medicine. American and European soft-drink manufacturers, however, do not use the kola nut; instead, they manufacture synthetic chemicals that resemble the flavour of the kola nut.Kola nuts are used locally as a medium of exchange. They are also commonly chewed by local labourers as a stimulant to diminish sensations of hunger and fatigue. Small pieces of kola nut chewed before meals act as an aid to digestion. In Brazil and the West Indies, the astringent-tasting nuts are used as a botanical drug to combat intoxication, hangover, and diarrhea.
