Uses: Primarily ornamental; a purgative is also made from the root and bark, and particularly the pulp of the fruit; bark as astringent for rheumatism; the bark also used for tanning.

Indigenous Legends: Flowers used as temple offerings in India; the pods were once “valued in medicine for their laxative properties, and exported from Java and the West Indies, chiefly Dominica,” to Europe.
