Astringent juice of an oriental tree.

An astringent substance, containing tannin, gum, and extractive matter, obtained from various African, Australian, and Indian trees.

An astringent extract of a deep brownish-red colour, obtained from certain tropical trees.

The trees, whence one variety of this resin is obtained, are not botanically ascertained. The London college ascribe it to Pterocar'pus erina'cea; the Edinburgh to Iron bark; and the Dublin to Butea frondo'sa. The Pharmacopoeia of the United States, (1842 and 1851), defines it to be "an extract obtained from an uncertain plant;" that of 1851 states it to be the inspissated juice of Pterocarp'us marsu'pium (De Candolle) and of other plants. On wounding the bark, the kino flows drop by drop. A West India variety is said to be derived from Coccol'oba uvif'era or Sea-side Grape; and a Botany Bay kino is said to be the concrete juice of Eucalyp'tus resinif'era or brown gum-tree of New Holland. Sex. Syst, Icosandria Monogynia. Nat. Ord. Myrtaceae. Kino consists chiefly of tannic and gallic acids, oxide of iron, and colouring matter. It is inodorous; the taste a sweetish bitter; and it is sometimes gritty between the teeth. It comes to us in fragments of a dark ruby red colour, and is easily pulverized. Its properties are powerfully astringent. Dose, gr. x to gr. xx in powder.
