This section is from the "Elixirs And Flavoring Extracts. Their History, Formulae, & Methods of Preparation" book, by John Uri Lloyd. Also available from Amazon: Elixirs and flavoring extracts,: Their history, formulae, and methods of preparation;
Fluid extract of May-apple, 2 fluidounces.
Simple elixir, 14 fluidounces.
Alcohol, 1/2 fluidounces.
Carbonate of magnesium, a sufficient quantity.
Triturate the fluid extract of May-apple 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 an amount of seven and one-half minims of fluid extract of May-apple as the menstruum can dissolve. Since resin of podophyllum is almost insoluble in water, we do not admire the above preparation.
