Distribution

J. multifida is native to tropical America from Mexico to Paraguay; it was introduced as an ornamental into the Old World tropics long ago. Within Malesia it is cultivated at least in Peninsular Malaysia, Java, the Moluccas and the Philippines.

Uses

The seed oil of J. multifida is sometimes used as a cathartic, although it may cause strong irritation and even poisoning. The oil is applied both internally and externally as an abortifacient. Seeds are used fresh as a purgative and emetic. The latex is used externally in the treatment of infected wounds, ulcers, skin infections and scabies. In Indonesia one of its local names is "yodium" ("iodine"), which reflects the popular use as a wound-healing remedy. In Indo-China, dried roots are given as a decoction against indigestion and colic; they are also prescribed as a tonic to treat orchitis and oedemas. The leaves are used as a purgative, and in the treatment of dysentery and scabies. J. multifida is widely grown, often in hedges, for its ornamental foliage and flowers. The tuberous roots can be eaten after roasting. The plant may also be used as a fish poison.
