The wood has a density of about 560 kg/m 3 at a water content of 12%. [12] The energy value of the wood as fuel is 19.741 kJ/kg. [10] Ashes of the wood are used in making soap and as a depilatory and tanning agent for hides. The wood is used for carving and the thorny branches useful for a natural barbed fence. [13]
