Fodder: The leaves are used as fodder in Nepal. Medicine: The bark is used medicinally against diarrhoea. Oxalic acid can be extracted from it. Tannin or dyestuff: The bark and especially the fruit yield pyrogallol and catechol to dye and tan leather. Timber: T. alata is a valuable and commercial source of timber and may have potential in other South-East Asian countries. The wood is used as terminalia e.g. for house building, furniture, tool handles, and for underwater purposes. When quarter-sawn, the wood yields attractive veneer.
