Sulphate of Soda. Aperient and diuretic. Seldom given to horses as a purgative (Mr. Clarke says 1 produces scarcely any effect); but is said to be useful in doses of 6 oz. 3 times a day, in epidemic catarrh. To cattle the usual dose is 16 oz., or from 12 to 20 oz., with ginger or caraway. It is considered more diuretic than Epsom salts.
Externally its principal employment is as an emollient in skin affections, accompanied by dryness and irritation, to excoriations, cracked heels, burns, scalds, and freshly blistered surfaces. When mixed with an equal bulk of solution of subacetate of lead, it is very serviceable in allaying irritability. Often added to masses to prevent their hardening.
Solution of Subacetate of Lead. Solution of Diacetaie of Lead. Cooling and astringent. Used externally only, in lotions, etc, in the same cases as sugar of lead. (See Lead, Acetate of.) For inflamed eyes, 1 dr. or 1 1/2 to a pint of distilled or boiled water; for other purposes it is made stronger.
A warm stimulant; chiefly used in cattle medicines. Dose, 3 to 6 dr.
A decoction of oatmeal. Nutritive and demulcent.
Sudorific and expectorant. It has been given to horses, in doses of 4 dr., in chest affections, farcy, rheumatism, etc.; and to cattle in doses of 4 or 6 dr. But its utility is doubted. The guaiacum wood is given to the amount of 4 oz., in decoction, repeated 2 or 3 times in 24 hours.
Emollient and demulcent. Used in inflammatory affections of the bowels, or of the respiratory or urinary organs. Dose, for horses and cattle, 1 to 4 oz., dissolved in water. For smaller animals, from 1/4 oz. to 1 oz. It is also used to suspend in water insoluble powders and oils. Gum Senegal and gum tragacanth are used for the same purposes. The latter will thicken twenty times as much water as Gum Arabic. [For Gum Ammoniac, Benzoin, etc, see Ammoniacum, Benzoin, &c]
Poisonous to all classes of animals. In small doses, it has been strongly recommended as a nauseant and diaphoretic, in inflammatory diseases; but it requires to be very carefully watched, otherwise a fatal collapse may be induced. The usual dose is 20 gr. every four or six hours till nausea is produced, or the pulse affected. Mr. Youatt says it cannot safely be given in doses of a drachm, but that it is given with advantage in ounce doses in chronic grease. Externally, it is used in ointments and washes for the mange; but even in this way its use requires caution. It is also blown into the nostrils as a sternutatory.
