=*Bismuthi Subcarbonas (Bism. Subcarb.), Bismuth Subcarbonate, U.S.P.=--Of varying chemical composition.
White or nearly white, odorless, tasteless powder. Insoluble in water or alcohol.
ACTION AND USES: Used like other insoluble salts of bismuth as a protective and healing agent against wounds, diarrheas, etc., and in x-ray work.
DOSAGE: 0.5 Gm. or 8 grains (U.S.P.) in powders or cachets or in suspension (best form)
=*Bismuthi Subgallas (Bism. Subgall.), Bismuth Subgallate, U.S.P.= (Dermatol).--A basic bismuth gallate of varying chemical composition.
Bright yellow, odorless, tasteless powder. Insoluble in water or alcohol.
ACTION AND USES: Similar to those of bismuth subcarbonate, over which it has no advantage.
=*Bismuthi Subnitras (Bism. Subnit.), Bismuth Subnitrate, U.S.P.=--Basic bismuth nitrate of varying chemical composition.
A heavy, white, odorless, almost tasteless powder. Almost insoluble in water and insoluble in alcohol. In aqueous mixtures, incompatible with alkali carbonates because of the liberation of nitric acid.
ACTION AND USES: Somewhat more astringent than the subcarbonate, because of the liberation of nitric acid.
DOSAGE: 0.5 Gm. or 8 grains (U.S.P.). Preferably administered as a powder or as cachets.
=Bismuthi Subsalicylas (Bism. Subsalicyl.), Bismuth Subsalicylate, U.S.P.=--Basic bismuth salicylate, of varying chemical composition.
A white or nearly white, odorless, tasteless powder. Almost insoluble in water or alcohol.
ACTION AND USES: Protective and astringent like other insoluble salts of bismuth, over which it has no marked advantage.
=Boldo (Boldo), Boldo, N.F.= (Boldo Leaves).
ACTION AND USES: Aromatic, perhaps somewhat diuretic. No well defined indications for its use.
_Fluidextractum Boldi (Fldext. Boldi), Fluidextract of Boldo, N.F._--Boldo (100%). Absolute alcohol content about 80 per cent.
=Brayera (Brayer.), Brayera, N.F.= (Kousso, Cusso).--Flowers.
ACTION AND USES: Teniacide; without advantage over aspidium or pelletierine.
