    (Dutch, Sulphophenylas Zincicus ; Russ., Zincum Sulfocarbolicum; Swiss, Zincum Sulfophenolicum; not in the others.) Medicinal Properties.—Astringent and antiseptic. For a spray to the throat, 5 grs. to the ounce of Water; for a collunarium, 2 grs. to the ounce; for vaginal injection, 60 grs. in a pint of Water, for leucorrhoea or gonorrhoea. ZINCI VALERIAHAS. VALERIANATE OF ZINC. Zn(C5H902)2, eq. 267. In bright white, pearly, tabular crystals, with a feeble odour of Valerianic Acid and a metallic taste. Solubility.—1 in 120 of Water; 1 in 60 of Eectified Spirit; 1 in 500 of Ether. Tests.—Its solution in hot Water is only faintly precipitated by Chloride of Barium (trace of Sulphate.) It gives, when heated with Diluted Sulphuric Acid, a distillate (Valerianic Acid), which, when mixed with solution of Acetate of Copper, does not immediately affect the transparency of the fluid (indicating absence of Butyric Acid), but forms after a little time oily drops, which gradually pass into a bluish-white crystalline deposit (Valerianate of Copper). Butyric Acid if present will form an immediate crystalline precipitate. The theoretical percentage of ZnO is 30-3 (with H2O 28'4). The examination of a number of commercial samples is given [P. J. xxiii., 190), the yield being from 21 to 64 p. c. of Oxide, and suggesting a minimum standard of 26 p. c. All the samples examined showed Butyric Acid by the copper test. The commercial praecip. generally contains a quantity of Oxide, but pure samples can occasionally be obtained. (Belg., Dutch, Fr., TluDg., Ital., Norw., Port., Russ., Span., Swed., Swiss and U.S. ; not in Austr., Dan. or Ger.) Medicinal Properties.—Antispasmodic, chiefly used in chorea, epilepsy, and in various neuralgic and hysterical affections. Dose.—1 to 6 grs. or more, in pill, with Extract of Gentian or Glucose. Inconipatibles.—All Acids, soluble Carbonates, most metallic salts, vegetable astringents. ZINGIBER. GINGER. The scraped and dried rhizome of Zingiler officinale. From plants cultivated in the West Indies, India, and other countries. (In all the Pharmacopoeias; Fr., Gingembre; Ital., Zenzero; Port., Gengibre; Span., Jengibre.)
