Medicinal Uses
The bark from fresh roots is chewed, and the juice swallowed as a treatment for boils. After several days the boils ripen, can be cut and squeezed out.
Known Hazards
No specific mention of toxicity has been seen for this species, but many members of this genus are known to contain pyrrolizidine alkaloids, the most potent of which in this genus are monocrotaline, retrorsine and retronecine. These alkaloids have a cumulative effect upon the body and, unless concentrations in a plant are high, occasional consumption is generally completely safe. Pyrrolizidine alkaloids are derived from amino acids including ornithine. Many of these alkaloids have pronounced hepatic toxicity, but the lungs and other organs may be affected as well. Mutagenic and carcinogenic activities of pyrrolizidine alkaloids have also been reported.
Distribution
A tropical plant. It grows between sea level to 3,000 m above sea level. It can grow in arid places.

Cultivation
Plants can be grown by seed.
Propagation
Seed - stored seed has a hard seedcoat and can benefit from scarification before sowing in order 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. Cuttings
Other Uses

Production
