Kola Nut

What is kola nut? The kola nut (or cola nut) is a seed of the kola tree. The tree is native to western and central Africa and can grow up to 40 feet tall. One tribe in Nigeria (the Igbo) consider it to be the first tree and fruit on earth. The flowers are white to yellow with a red to purple tinge and the seeds (about the size of a walnut) are white and bitter. When the seeds dry, they turn to a reddish-brown color and have almost no taste. In many African countries, it is used as part of cultural and social ceremonies and as medicine.


Kola nut has high amounts of caffeine and contains another stimulant (found in chocolate) called theobromine. It also contains starch, sugar, protein, fat, riboflavin, thiamine, niacin, and tannins.
