Kola nut is the seed of the Kola tree, native to the tropical rainforests of West Africa. It is known for its caffeine content and is often used in traditional ceremonies and as a stimulant. The nut has a bitter taste and is typically chewed or brewed into a tea. In addition to its cultural significance, kola nut is also used in the production of soft drinks, including the original formula of Coca-Cola. The nut contains other compounds that may have medicinal properties, although its primary use remains as a source of caffeine and flavoring.
