CATECHU (_Acacia Catechu_). A tincture of this plant is a pure, powerful
astringent, and is especially useful in chronic diarrhea, chronic
catarrh, and chronic dysentery. _Dose_--Of the powder, five to twenty
grains; of the tincture, one-half to two teaspoonfuls.

TANNIN (_Acidum, Tannicum_). This acid has a wide range of application.
It is used as an astringent. _Dose_--One to five grains.

GALLIC ACID (_Acidum Gallicum_). This remedy is used chiefly in
hemorrhages. _Dose_--Three to five grains. In severe hemorrhages, this
quantity should be administered every half hour, until the bleeding is
checked.


CARMINATIVES.


Carminatives are medicines which allay intestinal pain, arrest or
prevent griping caused by cathartics and exert a general soothing
effect. They are aromatic, and to a certain extent, stimulant.

ANISE-SEED (_Pimpinella Anisum_). Anise is a pleasant, aromatic
carminative, and is used in flatulent colic. _Dose_--Of the powdered
seed, ten to fifteen grains; of the infusion (a teaspoonful of seed to a
gill of water), sweetened, may be given freely; of the oil, five to ten
drops on sugar.

FENNEL-SEED (_Anethum Foeniculum_). This is one of our most grateful
aromatics, and is sometimes employed to modify the action of senna and
rhubarb. _Dose_--Same as that of anise-seed.
