This forms an unsightly mixture, yet it is very popular with some physicians. The antimonial wine contained in the preceding mixture will render it unpopular with the Eclectic profession, and the following old formula will more nearly meet with the approval of our physicians where a mixture of this kind is desired:

MISTURA GLYCYRRHIZAE COMPOSITA, Compound liquorice mixture.—Take of powdered extract of liquorice, powdered gum Arabic, and white sugar, each, 2 drachms; triturate these with water, 6 fluid ounces, added to them gradually, and when these are dissolved, strain the solution, and add to it camphorated tincture of opium, 1 fluid ounce; tincture of bloodroot, ½ fluid ounce; spirit of nitrous ether, 2 fluid drachms.

Action, Medical Uses, and Dosage.—The latter preparation forms an excellent cough mixture, and may be used in catarrhal affections after the subsidence of the more active symptoms, and when expectoration is present. An adult may take ½ fluid ounce for a dose, and a child 3 or 4 years old a fluid drachm. A very excellent cough remedy may be made as follows: Dissolve ammonium chloride, 2 drachms, in water, 6 fluid ounces; then add extract of liquorice, 2 drachms; extract of hyoscyamus, ½ drachm; when these are dissolved, add syrup of tolu, 1 fluid ounce. The dose is the same as the above, and may be repeated 3 or 4 times a day. A grain or two of the sulphate of sanguinarine may be added to render it more expectorant (J. King).
