Usage
The tree is a source of dammar resin. The dammar is a hard resin, obtained from various trees of Southeast Asia. Traditionally, it is used for purposes such as caulking boats and baskets, as an adhesive, a medicine, as a fuel for torches and sometimes in foods. The wood is a source of the ‘Mersawa’ timber. The hard, yellow wood is durable but difficult to saw due to a high content of silica. It is used for the construction of houses.
