Cola Tree: Uses, benefits, and side effects

The kola tree is native to tropical West Africa, primarily in Nigeria and from Sierra Leone to Gabon. It is cultivated in the tropical regions of Asia and America, but also in West and Central Africa and Madagascar. Kola seeds come primarily from imports from Nigeria and West African countries.

Cola tree as medicine

The dried seed kernels, freed from the seed shell, are used as a drug (Colae semen). The seed coat can be removed in a number of ways: either by soaking the seeds in water and then peeling off the shell, or by drying the fresh seeds and washing off the torn shell.

Cola Tree: Typical Characteristics

Kola seeds can be obtained from the two parent plants mentioned, Cola nitida or Cola acuminata (VENT.) SCHOTT & ENDL. descended. Cola acuminata is a tree up to 20 m tall. The mighty crown of this species already unfolds 1-2 m above the ground, while the branching of Cola nitida begins only 5-10 m above the ground.

The leaves are large (15-25 cm long) and entire; the leaves of Cola nitida are narrower. The flowers usually arise directly from the tree trunk; they are yellowish-white, about 1.5-2.5 cm in diameter and grow in umbel-like inflorescences.

Fruits and seeds of the cola tree

The tree also bears star-shaped follicles – about 5-15 seeds with a white seed coat can be counted per fruit. After removing the seed coat, the seeds of Cola nitida disintegrate into two, the seeds of Cola acuminata into four irregular parts.

The dried seed kernels or pieces thereof are between 2 and 4 cm long in the drug, hard and red to dark brown in colour. An essential part of the pieces are the cotyledons, which are flat to concave on the inside and irregularly curved on the outside.

Kola seeds: smell and taste
