The wood is very hard and heavy, it is reddish in colour and takes a
fine polish. It is used for mortars, bowls, and for building. The fruit
is edible, and the seed is known in commerce as Shea Nut. The kernels of
the nuts yield about 50 per cent. of fat called Shea Butter, which has
been found useful in the manufacture of candles, soap, and butter
substitutes. Locally it is used by the natives for food, for anointing
the body, and for lighting purposes.
