Glyceritum Acidi Gallici.—Glycerite of Gallic Acid.

Related entry: Acidum Gallicum (U. S. P.)—Gallic Acid

SYNONYM: Glycerin of gallic acid.

Preparation.—Take of gallic acid, 1 troy ounce; glycerin, 4 fluid ounces. Powder the gallic acid in a mortar, then gradually add the glycerin, rubbing the mixture constantly, until an even mixture is effected. Transfer this to a porcelain evaporating dish, and warm gently upon a water-bath, stirring constantly until the acid dissolves. This preparation should not be heated above the boiling point of water, 100° C. (212° F.), lest poisonous pyrogallol be formed (T. E. Thorpe).

Action, Medical Uses, and Dosage.—This preparation has been taken internally, instead of gallic acid in substance, in the several varieties of disease in which this acid is indicated, and is supposed to be more promptly absorbed when used in this form. Useful in inflammatory affections of mucous surfaces, as of the fauces, nasal membrane, ear, vagina, etc. It is to be applied locally, either as a wash, gargle, or injection. Its dose is from 10 minims to 1 fluid drachm. Externally it has been applied to the scalp, in cases of alopecia.
