Preparation.—"Citric acid, ten grammes (10 Gm.) [154 grs.]; water, ten cubic centimeters (10 Cc.) [162♏]; spirit of lemon, ten cubic centimeters (10 Cc.) [162♏]; syrup, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Dissolve the citric acid in the water, and mix the solution with five hundred cubic centimeters (500 Cc.) [16 fl℥, 435♏] of syrup. Then add the spirit of lemon, and, lastly, enough syrup to make the product measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Mix thoroughly"—(U. S. P.).
This syrup is prepared with less trouble than lemon syrup direct from the fruit, and can be preserved much better, but its taste is less agreeable.
Action, Medical Uses, and Dosage.—This syrup, added to water or to carbonic acid water, forms an agreeable cooling beverage for persons laboring under febrile complaints, and in certain states of the system requiring acids. From 1 fluid drachm to 1/2 fluid ounce may be added to 1/2 pint of the fluid in which it is to be taken.
