Fluid extract of eucalyptus, 2 fluidounces.

Fluid extract of licorice root, 1/2 fluidounce.

Fluid extract of wild cherry, 1/2fluidounce.

Simple elixir, 14 fluidounces.

Carbonate of magnesium, a sufficient quantity.

Mix the fluid extracts, and triturate them in a capacious mortar with carbonate of magnesium in amount sufficient to form a creamy mixture, then gradually add the simple elixir, stirring well, then filter.

Each fluidrachm of the finished elixir represents such an amount of seven and one-half minims of fluid extract of eucalyptus as will dissolve in one fluidrachm of the finished menstruum, and about two minims each of the fluid extracts of licorice root and wild cherry.

This preparation is intended as a pleasant mode of administering eucalyptus; but the proportion of eucalyptus represented is uncertain, owing to the fact that alcohol of specific gravity 0.820 is the proper solvent for the medicinal principles of the leaves. The formula we present is based upon ingredients suggested in the Druggists' Circular, 1877.
