Wild yam is a type of yam usually found growing uncultivated in tropical wild forest. There are quite upwards of 150 varieties. Their popularity stems from their medicinal uses. Their tubers are usually smaller than the regular yam or 'true' yams and are often referred to as rhizomes rather than tubers.
Wild yams form part of the diet of the pygmies of tropical regions of the world, from central Africa to Latin America and the Philippines.
They were used as food. The most popular of these yams are the Mexican wild yams which include the following: Diascora barbasco, Diascorae villosa, Diascorae batatas, Diascorae floribunda and Diascorae composita.
They are also called colic – root, devils bones or rheumatism root.
