Although poisonous, the plant is occasionally harvested from the wild for local medicinal use. It is also used as an adhesive. The bark and roots are the source of compounds for the the pharmaceutical industry. Between 1986 and 1995, about 16.5 tonnes per year were exported to Europe[
Although not currently evaluated for the IUCN Red List of Threatened Species(2013), because of the rapid destruction of the forests in which it occurs and harvesting for local use and export, the plant may become rare and locally threatened.

The bark and roots contain several monomeric indole alkaloids, of which reserpiline is pharmacologically active. It has sympatholytic and hypotensive properties, with no noticeable depressant effects on the central nervous system. In comparison with reserpine, which is present in other Rauvolfia spp., reserpiline does not induce the formation of gastric ulcers, has no laxative effects and lacks other side effects. The compound is used in quantity in the the pharmaceutical industry[
The latex can be used as glue for small utensils[
