Kola nut is a tropical caffeine-containing nut that emerges on evergreen trees of Cola nitida or Cola accuuminata. Traditionally, it is presented to esteemed guests or ceremonially to chiefs in the tribal culture of Western Africa. Cola nitida trees can grow up to a height of 40 to 65 feet with alternate glabrous, oblong, tough, and leathery leaves that have wavy and untoothed margins.
Cola nitida is grown in different tropical regions of the world due to its eminent kola nuts that are used in manufacturing cola, a popular soft drink. Kola nuts are habitually chewed in Africa to gain their stimulant and euphoric effects, all the while controlling the hunger pangs.
Medicinally, kola nuts are used to treat chronic fatigue syndrome, depression, melancholy, atony (reduced normal muscle tone), dysentery, atonic diarrhea, exhaustion, migraine, headache, and obesity. Kola nuts are packed with plenty of phytonutrients, including caffeine, theobromine, epicatechin, catechin, cardenolides, saponins, and tannins. All these active ingredients make up for the remarkable pharmacological activities kola nuts impart.
