Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen[
The gum is chewed and swallowed as a purgative[
The chewed gum, combined with the flowers of Tacca leontopetaloides, is used as a rub as an antidote to snake venom[
The plant, part not specified, is used in the treatment of gonorrhoea[
Gum exudates from cracks and wounds in the trunk are used to make a varnish called 'West African Gum Copal'[
A brown, fragrant balsam or oleo-resin is obtained from the trunk[
]. It is used as an adulterant of copaiba balsam (from Copaifera species), as a material for torches, to fumigate closed areas etc[
]. The fresh material is obtained by cutting out square pieces of the bark, though most of it is obtained from the ground in a semi-fossilized state[
The heartwood is pale pinkish to reddish-brown with occasional darker streaks; the 4 - 17cm wide band of sapwood is whitish to straw coloured. The texture is rather coarse; the grain straight to shallowly interlocked; the surface lustrous; may be somewhat gummy. The wood is light in weight, soft; it is not very durable, having a slight resistance to fungi and being susceptible to dry wood borers and termites. It seasons rapidly, with only a slight risk of checking or distortion; once dry it is moderately stable in service. The wood works easily with hand and machine tools, quartersawn material tends to tear in planing and shaping, produces a woolly finish unless tools are kept sharp, nails, screws well; gluing is correct, though assembling and gluing is sometimes difficult due to the warping of dried veneers. It is liable to sap stain, log conversion should be rapid. The wood is used for plywood, joinery, general millwork, furniture components, boxes and crates, a decorative veneer can be produced from selected logs[
