Medicinal Uses
The leaves of the species are used in Thai traditional medicine for postpartum (after childbirth) care. The bark and leaves, at times boiled, are used to treat a variety of ailments in Na Siao subdistrict, Chaiyaphum Province, northern Thailand. Villagers living on the plateau of Phnom Kulen National Park, Siem Reap Province, northwestern Cambodia, use dried pieces of the trunk and branches to make a "green tea" to treat stomachache, and use the wood-chips mixed with other plants in a decoction for postpartum care. Four ethnic groups living in the Wayanad District, Kerala, India, the Kattunaikkan, Kuruchiyar, Mullakuruman, and Adiyan people, use the plant to treat inflammation.
Known Hazards
The seed oil is very similar to that of Croton tiglium, and the seeds are likewise purgative and considered poisonous. Croton oil, obtained from the seed, is heavily irritating; contact with the skin causes inflammation and oedema. The toxic principles are crotonol, an extremely vesicant resin; and crotin, a delayed-action poison which causes blood-clotting. Symptoms of croton oil poisoning are firstly pain at the back of the throat, then in the anus. A dose of bismuth is an immediate antidote. Several esters of the diterpene phorbol have been isolated from croton resin. These are extremely irritant and also tumour promotors. Their presence in Croton tiglium and other Croton species means their consumption is sometimes held responsible for certain forms of nasopharyngeal cancer as they are able to activate Epstein-Barr viruses.
Distribution
It is a tropical plant.
Where It Grows
