PROPERTIES.--Ginger owes its taste to a pungent resin, its aroma to a volatile oil, and its medicinal and flavoring properties to both constituents, which are chiefly found in the delicate felted layer lying between the starchy, mealy parenchyma and the brown, horny, external covering. DOSE.--Horses, 2 dr. to 1 oz.; cattle, 1 to 4 oz.; sheep and pigs, 1 to 2 dr.; dogs, 5 to 15 gr. PREPARATIONS FLUIDEXTRACTUM ZINGIBERIS--FLUIDEXTRACT OF GINGER Made by maceration and percolation with alcohol, and evaporated so that 1 c. c. equals 1 gm. of the crude drug. DOSE.--Same as for ginger. TINCTURE ZINGIBERIS--TINCTURE OF GINGER Made by percolation of ginger with alcohol and water. DOSE.--Horses, ¹⁄₂ to 2 oz.; cattle, 1 to 4 oz.; sheep, 2 dr. to 1 oz.; pigs, 1 to 2 dr.; dogs, 15 to 30 m. OLEORESINA ZINGIBERIS--OLEORESIN OF GINGER DOSE.--Horses, 30 m. to 1¹⁄₂ dr.; dogs, 1 to 5 m. ACTION AND USES.--Ginger is an aromatic stimulant, and is used as a stomachic and carminative for all animals, notably for cattle and sheep. Ginger is administered internally, promotes gastric secretion, digestion and appetite. It is prescribed in atonic dyspepsia, often along with antacids and laxatives. Conjoined with purgatives it diminishes their tendency to nauseate and gripe, and also somewhat hastens their effects. The powder or fluidextract should be added to magnesium and sodium sulphate when given in full purgative doses to cattle or sheep. ZINCI PHENOLSULPHONAS--ZINC SULPHOCARBOLATE DERIVATION.--Zinc sulphocarbolate may be obtained by heating a mixture of phenol and sulphuric acid and saturating the product with zinc oxide. PROPERTIES.--Colorless, transparent, rhombic prisms or tabular crystals; odorless and having an astringent, metallic taste. Soluble in water and alcohol. DOSE.--Horses and cattle, 2 to 4 dr.; foals and calves, 5 to 10 gr.; sheep and pigs, 20 to 40 gr.; dogs, 4 to 6 gr. ACTION AND USES.--Zinc sulphocarbolate has been employed as an antiseptic astringent stimulant to indolent or foul wounds, and in subacute inflammations of the mucous membrane. The solution used may be a little stronger than those of zinc sulphate employed for similar purposes. It is also used as an intestinal antiseptic. ZINCI SULPHAS--ZINC SULPHATE DERIVATION.--Prepared by dissolving zinc in sulphuric acid. Iron and tin exist as impurities and are removed by chlorine solution and zinc carbonate. PROPERTIES.--A colorless, transparent, rhombic crystal, without odor and having an astringent, metallic taste. Efflorescent in dry air; soluble in water and glycerine; insoluble in alcohol. DOSE.--Horses and cattle, 1 to 2 dr.; sheep and pigs, 10 to 20 gr.; dogs, 2 to 3 gr. As an emetic for dogs, 10 to 15 gr.
