Uses
In Papua New Guinea leaf sap is used to cure stomach-ache or pain in the chest and shoulders. In the Philippines, there is one record of the bark being applied to treat an enlarged spleen. The stones have been a locally important trade commodity, in particular when the size was manipulated to obtain small beads called 'rudraksha'. At present they are still important for the production of traditional Hindu bead chains.
