Kino, a gummy resinous substance, exuding from incisions made in a tree called Pau de San-gue, a native of the inland parts of Africa, but of which there is no botanical account.

From its sensible qualities, and also by its striking a black colour with a solution of green vitriol, this drug is remarkably astringent. It was first recommended by Dr. FothErgill, and is now often prescribed in diarrhoeas, fluxes, etc. It affords an extract both in spirits and in water, but is more generally given in the form of a tincture, from one to two tea-spoonfuls, three or four times in 24 hours.
