Uses
The plant has a large number of traditional medicinal uses, including for rheumatism, asthma, cholera, and fever. Some in vitro and rodent studies have suggested that extracts of the plant may inhibit tumors, protect liver cells from damage in acetaminophen overdose, and reduces complications of hyperlipidemia in diabetic rats. There have been no published studies testing any of these effects in humans.
The fibrous bark is used to make rope.
