The plant is a source of alkaloids.
The bark contains the alkaloids cassaine, cassaidine and erythrophleguine. The alkaloid content ranges from 0.2% to 1.1%. In high doses, the bark extract is an extremely strong, rapid-acting cardiac poison, in warm-blooded animals causing shortness of breath, seizures and cardiac arrest in a few minutes[

The heartwood is an orangey yellowish brown to reddish brown, darkening upon exposure; it is clearly demarcated from the 3 - 6cm wide band of creamy-yellow sapwood. The grain is interlocked; the texture coarse; the lustre is moderate. The wood is hard to very hard; heavy to very heavy; elastic; durable, even in contact with the soil, being resistant to fungi, dry wood borers and termites. It seasons slowly, with a high risk of checking and distortion; once dry it is moderately stable to stable in service. The wood is difficult to saw, with a fairly high blunting effect, stellite-tipped sawteeth and tungsten carbide tools are recommended; finishing is generally fair, but planing may be difficult due to interlocked grain; pre-boring is necessary for nails and screws; gluing properties are good for internal purposes only. The wood and iron should not be in contact in damp situations because of risks of reciprocal attack between the wood and the metal. The wood is suitable for joinery, heavy flooring, railway sleepers, harbour and dock work, turnery, construction and bridges. It is also used for boat building and wheel hubs[
