Fruits are reported to be a good source of nutrients for desert animals. The fleshy fruits are eaten by birds. The young twigs serve as a fodder for camels and goats. The wood is light yellow to pale brown, smooth, moderately hard and heavy and resistant to termites. It is suitable for making small beams, rafters, knees of boats, for oil mills, tool-handles, cart-wheels and axles, and to a small extent in making combs. A paste of the coal from the burnt wood is applied for muscular injuries. The wood also serves as a fuel. The plant is used for making huts and fences. It can also serve as wind-break especially in dry localities.
The fruits are astringent, and useful in cardiac troubles and biliousness. The root and bark contain 28 and 31 percent protein, respectively. The bark is anthelmintic and useful in cough, asthma and inflammations. The tender leaves are applied as a poultice on boils and swellings. They are chewed to relieve toothache.
