Kola nut is the fruit of the kola tree which is native to West Africa. In an average star-shaped fruit, about 2–5 nuts will be present. Although they have a bitter taste when freshly plucked, drying in the sun makes them taste milder with time. It contains about 2–3 percent caffeine and 1–2 percent theobromine, both of which have psychostimulating properties.
It also has minerals like potassium, magnesium, and calcium which makes it quite beneficial for human consumption. It shouldn’t be confused with bitter kola, the nut from the flowering plant Garcinia kola, that has several healing abilities. Kola nuts are also unrelated to gotu kola which is a medicinal herb used in Chinese and Indian medicine.
