Usage

Uses. GAMBLE, L.C. 516, said it is in SE. Asia rather an important large tree by its durable timber which is easy to work and good for building, though the amount of heartwood is small. It also is an excellent fire-wood and makes good charcoal. The root and bark are used as a favourite tonic native medicine. It also is important in sylviculture for its very free seed reproduction; the fruit remains long unopened on the tree and seed gets dispersed at the very end of the hot season after the danger of fire is nearly over, and can germinate with the first rains. Even on exposed slopes and among grass its good natural reproduction is noticeable.BURKILL ( BURKILL Diet. 1935 2082 ) mentions that it yields a gum of the tragacanth class. He also mentioned that it is referred to as a plant of magic in Sanskritic India, patala, being the Sanskrit name, of which modern vernaculars have been derived. In this respect it is noteworthy that the Javanese name 'bedaW is a name for Radermachera spp. TRIMEN reported it in Ceylon planted near Buddhist temples.
