'''Kola nut''' ('''''Cola''''') is a genus of about 125 species of [[tree]]s native to the tropical [[rainforest]]s of [[Africa]], classified in the family [[Malvaceae]], subfamily [[Sterculioideae]] (or treated in the separate family [[Sterculiaceae]]). It is related to the [[South America]]n genus ''Theobroma'' ([[Cacao]]). They are [[evergreen]] trees, growing to 20 m tall, with glossy ovoid [[leaf|leaves]] up to 30 cm long.
;Selected species
* ''[[Cola acuminata]]'' — Abata Cola
* ''Cola anomala''
* ''Cola gigantea''
* ''Cola heterophylla''
* ''[[Cola mossambicensis]]''
* ''Cola nitida'' — Goro
* ''Cola pachycarpa''
* ''Cola vera''
* ''Cola verticillata''
=== Uses ===
[[Image:Koeh-190.jpg|thumb|left|''Cola acuminata'']]
The kola nut has a bitter flavor and [[caffeine]] content, and is chewed in many [[West Africa]]n cultures, individually or in a group setting. It is often used ceremonially, presented to tribal chiefs or presented to guests. Chewing kola nut can ease hunger pangs. Frequent chewing of the kola nut can also lead to stained teeth. Among the urban youth of West Africa, kola nut is becoming less popular.
Kola was originally used to make [[cola]] [[soft drink]]s, though today most of these mass-produced beverages use artificial flavourings. Some exceptions are [[A.G. Barr plc|Barr]]'s [[Red Kola]], Harboe Original Taste Cola, [[Foxon Park|Foxon Park Kola]], Blue Sky Organic Cola, Sprecher's Puma Kola, and [[Cricket Cola]], the later being made from kola nuts and [[green tea]].
Outside of Africa, some species are cultivated for their nuts in [[Indonesia]], [[Brazil]], [[Jamaica]] and elsewhere in the humid tropics. <br clear = left>
=== Safety issues ===
Kola nuts contain high amounts of N-nitroso and tannins compounds, which are carcinogenic. In Nigeria, where the chewing of Kola nuts is a common practice, there is a high incidence of oral and gastrointestinal cancer which may be related to this habit.
=== History ===
The kola nut, like the coffee berry and tea leaf, appears to have ancient origins. It is chewed in many West African cultures, individually or in a social setting, to restore vitality and ease hunger pangs. In 1911, kola became the focus of one of the earliest documented health scares when the US government seized 40 barrels and 20 kegs of Coca-Cola syrup in Chattanooga, Tennessee, alleging that the caffeine in its drink was "injurious to health". On March 13, 1911, the government initiated The United States vs. Forty Barrels and Twenty Kegs of Coca-Cola, hoping to force Coca-Cola to remove caffeine from its formula by making exaggerated claims, such as that the excessive use of Coca-Cola at one girls' school led to "wild nocturnal freaks, violations of college rules and female proprieties, and even immoralities." Although the judge ruled in favor of Coca-Cola, two bills were introduced to the U.S. House of Representatives in 1912 to amend the Pure Food and Drug Act, adding caffeine to the list of "habit-forming" and "deleterious" substances which must be listed on a product's label.
