Native to tropical America and the Caribbean, A. cathartica is now cultivated throughout the tropics.


Throughout South-East Asia, a decoction of the leaves is used as a purgative or emetic. In the Philippines, a decoction of the plant is used as an antidote. However, large doses may result in poisoning. In Java a steaming infusion is used to relieve coughs and headaches; the patient breathes in the vapour. In South America, the leaves or latex are used as a purgative. In Peru, the bark is used as a febrifuge. In Suriname, a decoction of the root is taken as a remedy for jaundice and enlarged spleen resulting from malaria.
