The oil is obtained by cutting a hole in the trunk near the base (about 90 - 150cm from the ground) and then dipping out the resin with a spoon as it collects there. To prolong the flow, a fire made from dead leaves or brushwood is made in the hole at intervals - this burns off the dried resinous film and allows the resin to flow again[

]. We do not have specific information for this plant, but a general description of the wood is as follows:-
The heartwood is light red to red brown or purplish red brown; it is clearly demarcated from the 5 - 7cm wide band of sapwood. The texture is coarse; the grain straight or interlocked. The wood is moderately heavy to heavy; moderately hard; somewhat durable, being resistant to dry wood borers, fairly resistant to fungi but susceptible to termites. It seasons slowly, with a high risk of checking and distortion; once dry it is poorly stable to moderately stable in service. It has a high blunting effect on tools due to the presence of silica, stellite-tipped and tungsten carbide tools are recommended; some species are very resinous and can clog tools; there is occasional tearing on quartersawn wood; nailing and screwing are good, but require pre-boring; gluing is correct, but care is required because of the resin. A general construction timber, it is used in carpentry, panelling, joinery, floors, timber frame houses, boxes and crates, veneer etc[
