This wood is of a very fine colour, and is used in woodturning for making knife handles and similar articles. The tree's bark and heartwood are commonly used to make a brilliant but non-permanent red dye, which is soluble in alkali.Camwood is known as "osun" in Yoruba and is a key ingredient in Dudu Osun, a Nigerian brand of black soap.
