Grows best in a sunny position[
The bark is used to treat snakebite[
A decoction of the scented stem bark is used in an external wash as a treatment for fevers[
The plant contains polycarpol[
A fibre is obtained from the inner bark[
The sapwood and heartwood are not clearly demarcated. The wood is light in weight with a low resistance to insect attack. Of low quality, it is only used for making light boxes[
The wood is of low value as a fuel[
Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Sow the treated seed as soon as it is ripe in a partially shaded position in a nursery seedbed. A germination rate can be expected, even if the seed is treated, with the seed sprouting within 50 - 70 days[
