Dipterocarpus alatus in Kentung Burma

In Cambodia the wood is much valued in construction and cabinetwork, when not exploited for its oily resin. Generally, resin is collected for the following uses: wood lacquering, draught-proofing of boats and traditional medicine. When mixed with beeswax, it is used in bandages for ulcerated wounds. The bark of young trees is also used in traditional medicine, taken against rheumatism and diseases of the liver, and to stimulate appetite in cattle.[2]

In Myanmar/Burma one of the largest of the species is in KengTung, photos shown here: Nov 2014
