Cola trees are a genus of plants in the stink tree subfamily (Sterculioideae) within the mallowfamily (Malvaceae). The cola tree is a tree up to 25 meters high, which is native to Africa south of the Sahara, India and South America. The fruit of the tree, the so-called kola nut, is not a nut but the seed of a bellows fruit. This is a valued stimulant due to its stimulating effect. Supplying countries are Nigeria and other West African countries.

The dried seeds (cola seeds) of two different cola species are used phytotherapeutically: Cola nitida and Cola acuminata. Cola nitida is a 10 to 15 m high tree with an unbranched trunk, Cola acuminata is up to 20 m high and is only sparsely leafy, the branching begins just above the ground.

Ingredients: Cola seeds contain caffeine (approx. 2.5 %), theobromine (0.1 %); catechin and epicatechin, tannins and oligomeric procyanidins, starch approx. 40 %; also contains small amounts of proteins, sugars and minerals.

Cola nitida is the parent plant of Colae semen (kola nut). The cola tree has become very well known through the mixed drink "Coca-Cola". Due to the high demand in the last century, the number of cultivated cola trees increased enormously, especially in the West African countries that export the cola nut.

Extracts from the kola nut (Cola nitida extract) are used in cosmetic preparations, e.g. as cellulite agents.
