Kola nuts are the seeds of the kola tree, native to the tropical rainforests of West Africa. They are typically oval-shaped and have a bitter taste. Kola nuts are often chewed for their stimulating effects due to their caffeine content, similar to that found in coffee and tea. In many cultures, kola nuts hold significant social and ceremonial importance. They are commonly used in traditional rituals and as a symbol of hospitality. Additionally, kola nuts are sometimes processed to create soft drinks, contributing to the flavor of popular beverages like cola.
