Dioscorea bulbifera bulbils are used in the treatment of Piles, dysentery, syphilis, ulcers, cough, leprosy, diabetes, asthma, and cancer. It is a raw material for contraceptives, and it is one of the most consumed yam species especially in West Africa. Unfortunately, this plant is at the verge of extinction because of increased harvest for medicinal purpose. This review aims at providing up-to-date information about its photochemistry, clinical benefits, conservation status and best possible way on how this plant can be conserved for future use. Literature database search was employed, and the findings indicate that much as Dioscorea bulbifera is of diverse clinical and ethnomedicinal benefits, it’s vulnerable to extinction. In order to conserve Dioscorea bulbifera, there is a need to enlighten the local inhabitants on its clinical and commercial importance and uses. Also for the sustainable growth of the plant, the government and Non-governmental agencies have to distribute Dioscorea bulbils to the farmers for planting and also encourage its planting back into the wild. In addition, micropropagation of the D. bulbifera will be the perfect tool for re-establishing the plant in the natural habitat with more advantages of improving growth conditions of the plants.
