Uses.--The trunk bark is astringent and in decoction is of use in the treatment of prolapsed rectum and as an injection for leucorrhoea. A poultice of the tender leaves is applied to ulcers and sores previously washed with the decoction. The tree exudes an abundant gum very similar to gum arabic which latter is the product of another species of acacia (_A. Arabica_, Willd.). The Manila pharmacist, D. Anacleto del Rosario, sent to the Paris Exposition of 1899 a specimen of this gum obtained on the plantation of D. P. P. Roxas, in Batangas. This specimen differed in no respect from gum arabic and it will surely sooner or later take the place of the latter in the Philippines, both for pharmaceutical and industrial purposes. It would be superfluous to describe here the properties of gum arabic. Botanical Description.--A small tree 9-12° high, very well known, trunk bristling with long thorns.

Uses.--The fleshy leaves are beaten up and applied to chronic ulcers and sores on which they exert a stimulant action. Applied to the temples they relieve headache. Ainslie testifies to the good effect of its local use in inflammations and as a wash for ulcers. The juice of the leaves is used in Concan in the treatment of bilious diarrhoea and gall stones.
