COLA NITIDA 1) INTRODUCTIONA tropical tree from West African rainforests, Cola nitida is best known for its caffeine-containing seeds, known as kola nuts. Raw seeds are chewed as a stimulant and have a bitter taste. Kola nuts are used in a variety of local ceremonies and also to produce kola nut extract, which is an ingredient in some soft drinks.

The closely related species Cola acuminata is also sometimes known as kola nut, and its seeds are used in the same ways. Cola nitida and C. acuminata are known as true kolas, yielding superior seeds for chewing. Although seeds of some other Cola species are suitable for chewing, they are of an inferior quality and are known as false kolas or monkey kolas

4) ADVANTAGE & USESCola nitida seeds, known as kola nuts, are used as a foodstuff locally. They contain caffeine, theobromine, tannins, fructose and kolanin (a heart stimulant). They are chewed as a stimulant and are especially favoured as a snack by African Muslims when fasting in the month of Ramadan. Kola nuts are reported to suppress hunger and thirst and have been used in western and central Africa for thousands of years.

Kola nut extract was reportedly used as a source of caffeine in pharmacist John Pembertons French Wine Coca, a forerunner of the soft drink Coca-Cola. Frank M. Robinsons first advert for Coca-Cola in the Atlanta Journal on 29 May 1886 read Coca-Cola containing the properties of the wonderful Coca plant and the famous Cola nut. Natural kola nut extract has now been replaced by synthetic citrate caffeine in many leading brands of cola drink, although some advertised as natural cola include kola nut in their ingredients.

Kola nuts are used in many African ceremonies, for example the welcoming ceremony of the Igbo culture of Nigeria. The seeds are passed among visitors to a village and then blessed by the village elder, before a seed is given to each visitor with the words j luo n okwuo ebe osi bia (When the kola nut reaches home, it will tell where it came from), proof to the visitors people of his visit to the other village. Kola nuts are central to many other ceremonies in western and central Africa including marriage, child naming, investiture of tribal chiefs, funerals and sacrifices to deities.

Seeds from Cola nitida and C. acuminata have been used in western African and Anglo-American herbal medicine as an antidepressant. They have also been used to treat headaches, migraine, dysentery and diarrhoea. In Africa, C. nitida bark is used to treat wounds and swellings, roots to make teeth-cleaning sticks, and pod bark mixed with other ingredients to reduce labour pains.

In the past, kola nuts have been given to troops on African battlefields, with the aim of enabling prolonged exertion without fatigue or thirst but also preventing dysentery and even supposedly giving rise to a feeling of bravery. Further research is needed to verify the medicinal properties of Cola nitida.Cola nitida seeds are also used for dyeing, water purification and production of liquid soap and fertilisers. By-products of kola nut processing are used as poultry feed. Its timber is used for furniture and as fuelwood.
