Edible Uses

Edible portion: Seeds, Herb, Flavouring, Fruit, Leaves. The aromatic seed is rich in caffeine, containing 1.25 - 2.4% caffeine, and acts as a stimulant[ 238 , 301 ]. It can be chewed or ground into a powder and made into a drink in order to give energy, increase alertness, retard hunger and fatigue, aid digestion and increase stamina[ 301 ]. When the whole nuts are chewed, they taste bitter at first but they leave a sweet taste in the mouth later that affects other foods or drinks that are consumed[ 301 ]. Thus chewing cola nuts before drinking water helps to render the water sweeter[ 303 ]. The bitter tasting seeds are much appreciated by Muslims in the drier region of West Africa, especially during the month of Ramadan[ 303 ]. The nuts are used for non-alcoholic soft drinks like Coca-Cola[ 303 ]. An extract, prepared from the dried kernels, is used to flavour carbonated drinks, ice cream, candy, baked goods etc[ 301 ]. The kernels can be red, white or pink[ 301 ]. The red ones can be used as a natural food colorant[ 301 ].

Medicinal Uses

Cola nuts contain up to 2.5% caffeine, plus theobromine, tannins, phlobaphene and an anthocyanin[ 254 ]. They stimulate the nervous system when chewed and are also considered to be a digestive tonic, diuretic, astringent and antidepressant[ 254 , 303 , 307 ]. They counteract overstrain and depression thus improving the physical and mental state. The principle action is that of caffeine. Other active principles include theobromine and kolatine[ 303 ]. Because of its astringent properties, cola is used as a non-addictive stimulant in the treatment of diarrhoea and dysentery[ 254 , 303 ], and also to prevent vomiting in cases of high fever[ 303 ]. It has also been used in the treatment of headaches and migraine[ 254 ]. It has been used in combination with coca leaf (Erythroxylum coca) to produce a stimulant drug that has been used as 'Forced March' tablets by explorers and military expeditions[ 303 ]. The crushed nuts are boiled together with the leaves of Morinda lucida and the liquid taken internally to cure piles[ 303 ]. The nuts ground to a fine paste together with the leaves of Scoparia dulce, are dissolved in a little water and a few drops are administered orally to babies for headache[ 303 ]. The seeds are harvested when fully ripe and dried in the sun[ 254 ]. An infusion of the bark mixed with ginger and a little pepper is taken internally to cure stomach ulcers[ 303 ].

Other Uses

Other Uses: The seed is reputed to act as a water purifier[ 303 ]. The sapwood is pinkish-white and the heartwood dull yellow. It is suitable for furniture, house and boat building, coach-work, plates, domestic utensils, gun stocks, joinery and carvings[ 303 ]. The wood is a good source of fuel[ 303 ].

Cultivation details

Cola needs a hot humid climate, with a mean annual temperature in the range 26 - 35c, and a mean annual rainfall of 1,200 - 1,800mm[ 303 ]. However, it can withstand a dry season on sites with a high ground water level and it may be cultivated in drier areas where ground water is available[ 303 ]. Though it is a lowland forest tree it has also been found at altitudes over 300 metres on deep rich soils under heavy and evenly distributed rainfall[ 303 ]. Prefers a minimum temperature no lower than 13c[ 238 ]. Prefers a deep, rich, well-drained soil[ 303 , 307 ], although it may also be found in marshy areas[ 303 ]. Does well in both light and heavy soils[ 303 ]. Intolerant of soils with a high pH[ 335 ]. Cola grows naturally in the shade, but it develops a better spreading crown which yields more fruits when grown in open places[ 303 ]. Trees start producing at around the age of 12 - 15 years and can produce 10 - 16 kilos of seed annually for more than 80 years[ 238 ]. Trees commence flowering and fruiting when they are small[ 307 ]. Yields of 300 nuts per mature tree are considered good[ 303 ]. Plants are often used as shade trees for cocoa (Theobroma cacao) plantations[ 238 ]. Muslims consider the cola nut as sacred and brought by the prophet Mohammed. They use the nut for ceremonial and social occasions[ 303 ].
