Fluid extract of matico, 2 fluidounces.

Simple elixir, 14 fluidounces.

Alcohol, 1/2 fluidounce.

Carbonate of magnesium, a sufficient quantity.

Triturate the fluid extract of matico in a capacious mortar with carbonate of magnesium in amount sufficient to form a creamy mixture, then gradually add the simple elixir, stirring well, and filter. Lastly, mix the filtrate with the alcohol.

Each fluidrachm of the finished elixir represents such part of seven and one-half minims of fluid extract of matico as will dissolve in the menstruum employed in its preparation. We consider alcohol of specific gravity 0.820 to be the proper menstruum for exhausting the medicinal principles from matico, and the addition of water decreases its solvent power in proportion to the amount of water added. In consequence of this fact we object to an elixir of matico.
