Description Cola nitida Linn (Sterculiaceae) is an economic plant widely distributed throughout West Africa and possibly other parts of Africa.Members are malvalves because of their lobular nature. Because of its ubiquity, the plant plays an important role in commerce, and in social activities where it is casually eaten without prescription or restriction. The ethnopharmacological effects of bolus ingestion of 30g of Cola nitida was investigated on visually acute and healthy volunteers in order to determine its ocular implications or effects. Results showed that Cola nitida had no effecton the pupil diameter, visual acuity and intraocular pressure but improved the near point of convergence by 43% and increased the amplitude of accommodation by 11% while existing heterophorias are ameliorated. The stimulating effect of Cola nitida might overcome asthenopic symptoms with convergence insufficiency and allows near work to be donewithout stress. Somnolence and ocular muscle imbalance common features of the elderly canbe ameliorated or relieved.
