Hymenodictyon orixense (Roxb.) Mabb. (= H. excelsum (Roxb.) Wall.)


Hymenodictyon orixense (Roxb.) Mabb. (= H. excelsum (Roxb.) Wall.) 


Myanmar: dumsa-gyaw, khu-than, mai-son-pu. English: bridal couch tree.


India, Myanmar, Indo-China, Thailand, Peninsular Malaysia, Sumatra, Java, the Lesser Sunda Islands, the Philippines, Sulawesi, and the Moluccas. In Myanmar, found in Bago, Mandalay, and Yangon.


Bark: Used as a febrifuge and tonic.


In Indo-China the bark is used as tonic; also, the species apparently has two varieties- var. Hymenodictyon orixense subglabrum  Pierre, of which the pulverized wood is found in native pharmacies as a remedy for skin diseases, and var. Hymenodictyon orixense velutinum  Pierre, which is especially used as a women’s remedy ( Perry 1980). In the Philippines the species is a substitute for Cinchona  due to its antiperiodic effects, also the leaves are applied as a poultice for headache ( Perry 1980).

Reported constituents include a catechol tannin containing phloraglucin, some phlobaphenes, traces of catechol tannin without phloroglucin (analogous to quinatannic acid) not combined with alkaloid, oxycoumarin, B-mannose, methyl sugar, and heteroside of which some elements could not be isolated ( Perry 1980).
