Description of Use

Young soft leaves - raw or cooked. Eaten as a vegetable. Eaten in salads or used as a condiment. The brown, reddish, or blue-black fruit is fleshy, around the size of a pea and in three segments. The plant has been shown to have antiulcer, anthelmintic and antidysenteric activities. The fresh bark is used to treat aching stomachs. The sap of the bark, mixed with lime, is used to treat sore feet. The crushed leaves are rubbed onto an aching stomach. Agroforestry Uses. The tree is used for reforestation and is often intercropped in traditional agriculture. In India, it is considered to be an excellent shade tree in coffee and cardamom plantations. The tree is planted as a pioneer species in northern Thailand in reforestation projects to restore native woodland - it is planted in degraded woodland and open areas in a mix with various other species that all have the ability to grow fast; produce dense, weed-suppressing crowns; and attract seed-dispersing wildlife, particularly birds and bat. A red dye obtained from the bark is used to stain rattan baskets. A brown dye obtained from the inner bark is used to color tapa bark cloth. The bark contains about 16 % tannin that is employed in the toughening of nets and ropes. The heartwood is purplish-brown to reddish-brown and is sharply differentiated from the narrow, pale brown to pale reddish-brown sapwood. The wood is medium-weight and moderately hard. The grain is generally interlocked; texture moderately fine to rather coarse and even; wood surface dull to slightly glossy. Fresh wood smells of vinegar. The wood is susceptible to Lyctus and dry-wood termite attack, longhorn and ambrosia beetles as well as wood-rotting fungi. The wood is used for general construction (beams, posts), bridges, decking, sleepers, mining props, flooring, interior finish, veneer, plywood, implements, carving etc. The tree is a potential source of long fibers for pulp and paper production.  Although the wood is not suitable as fuelwood, it is used for charcoal production.
