ngurjunThe Dipterocarpus alatus, a very large tree of the East Indies and Philippine islands, the wood of which is used for house-building and canoes. This and other species furnish an oleoresin known as wood-oil or gurjun balsam, which is used as a substitute for balsam of copaiba, as a varnish and an ingredient in the coarser kinds of paint, as a substitute for tar in pitching boats, and for preserving timber from the attack of the white ant. As a medicine it is used in gonorrhea, and as an excitant in salves for inveterate ulcers.
Chaulmoogra oil and gurjun oil internally and externally are in some instances of service.
