Fluid extract of jaborandi, 1 fluidounce.

Simple elixir, 14 fluidounces.

Alcohol, 1/2 fluidounce.

Carbonate of magnesium, a sufficient quantity.

Triturate the fluid extract of jaborandi 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 will contain the medicinal principles of three and three-fourth minims of fluid extract of jaborandi.

In former editions of our publication two fluidounces of fluid extract of jaborandi were used in making sixteen fluidounces of the elixir. The National Formulary recognizes one fluidounce, and we change our proportions to conform therewith.
