Economic Importance:

  • The wood is used for manufacturing packing cases and boxes for packing tea, writing boards and lamina boards. Wood charcoal is used for gun powder.
  • Can be peeled easily and accepted as suitable for 3rd class commercial plywood after necessary treatment.
  • It is good enough for making both match boxes and splints, also fairly suitable for second grade pencil and paper industry.
  • Bark which is bitter in taste is used as an astringent, tonic and useful for diarrhoea and dysentery. The milky juice of bark is applied to sores and ulcers. Bark also yields a fibre.
  • Flowers yield an alkaloid ‘Picrinine‘ which acts as a depressant on the central nervous system.
