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.--
