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 hops, 2 fluidounces.
Fluid extract of orange peel, 1/2 fluidounces.
Simple elixir, 14 fluidounces.
Alcohol, 1/2 fluidounce
Carbonate of magnesium, a sufficient quantity.
Mix the fluidextracts, 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, 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 hops as will dissolve in the menstruum.
The ingredients for the above mixture were named by the Druggists' Circular, 1876. We do not consider an aqueous menstruum to be well adapted to the purpose of exhausting the medicinal principles of hops, hence we think that this elixir is not a desirable preparation.
