African oil bean seed, scientifically called Pentaclethra macrophylla, is one of the many tropical under-utilized crops that are recently attracting worldwide attention because of its high nutrient. It is a native plant in the tropical regions of Africa. The oil bean tree is mainly found in rainforests southern West Africa where they grow wildly.
