Syrupus Scillae (U. S. P.)—Syrup of Squill.
Preparation.—"Vinegar of squill, four hundred and fifty cubic centimeters (450 Cc.) [15 fl℥, 104♏]; sugar, eight hundred grammes (800 Gm.) [l lb. av., 12 ozs., 96 grs.]; water, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Heat the vinegar of squill to the boiling point, in a glass or porcelain vessel, and filter the liquid while it is hot. Dissolve the sugar in the hot filtrate by agitation, without further heating, strain, and, when the strained liquid is cold, add enough water, through the strainer, to make the product measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Mix thoroughly"—(U. S. P.). The object in heating the already prepared vinegar of squill is to coagulate the albuminous substances present, which are subsequently removed by filtration. Avoid metallic vessels in the preparation of this syrup.
Action, Medical Uses, and Dosage.—Syrup of squill is used as an expectorant in coughs and catarrhs, and as an emetic in affections of the air passages in infants. It is frequently given in combination with tincture of lobelia and other emetic or expectorant agents. A fluid drachm is the usual dose.
