Kino is a powerful astringent.

It is used externally  to ulcers, to give tone to them when flabby, and discharging foul and thin matter.

It is used internally  in the same diseases as catechu.

Dose , of the powder, from ten to fifteen grains; of the tincture , from one to two drachms; of the compound powder , from ten to twenty grains; of the infusion , from a half to one and a half ounce.

Caution .—Kino is used in combination with calomel, when salivation is intended, to prevent, by its astringency, the action of the calomel on the bowels, and thereby insure its affecting the constitution.— (See Catechu ).
