Bitter kola otherwise knowm as Garcinia kola is relative present across West African countries such as Benin, Cameroon, Democratic Republic of the Congo, Ivory Coast, Gabon, Ghana, Liberia, Nigeria, Senegal and Sierra Leone.
Bittter Kola belongs to as a species of flowering plant in the Clusiaceae or Guttiferae family.Its natural habitat is subtropical or tropical moist lowland forests.
Garcinia kola is a tree that grows in the rain forests of west Africa. The fruit, seeds, nuts and bark of the plant have been used for centuries in folk medicine to treat ailments from coughs to fever. Research as shown that garcinia kola trade important to the tribes and villages in Nigeria (Center For International Forestry Research).

Importance of Garcinia kola is in no small measure. It is traditionally used by African medicinemen who believe that it has purgative, antiparasitic, and antimicrobial properties. The seeds are used for bronchitis, throat infections, colic, head or chest colds, and cough. It is also used for liver disorders and as a chewing stick.


However despite the socio-economic importance of Garcinia kola, the cultivation of the species is very much limited. Factors that have discouraged farmers from growing Garcinia kola include difficulties encountered in the germination which reduces the availability of seedlings in the nurseries for possible plantation establishment. Most of the productive trees are those which were left in the wild when farm plots were cut out of the forest (Adebisi, 2004). Researchers have studied the germination problems of G. kola seeds and suggested various means of breaking its dormancy (Gyimah, 2000, Anegbeh et al., 2006, Kanmegne and Ndoumou, 2007, Oboho and Urughu, 2010, Oboho and Ogana, 2011).

Needless to say that there is still a great need to investigate more simple and practicable methods that could be easily adopted by the farmers with low technological input. G. kola seeds has both seeds coat dormancy and physiological dormancy probably imposed by the chemicals in the seed (Oboho and Urughu 2010). Seed coat dormancy of Garcinia kola can be reduced by removing the seed coat before sowing while the physiological dormancy can be reduced by soaking in water for 72 hours (Yakubu et al., 2014). the removal of the seed coat, soaking in water for 72 hours, placing inside air tight transparent polythene bag and sprinkling of water on the seeds when needed for constant moisture will give early germination period of 2 weeks (Yakubu et al., 2014).
