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;
Elixir of valerianate of quinine, 14 fluidounces.
Distilled water, 2 fluidounces.
Strychnine, 1 1/4 grains.
Valerianic acid, a sufficient quantity.
Powder the strychnine in a mortar and add the water, and then enough valerianic acid to effect the solution of the strychnine. Lastly, add the simple elixir, and filter if necessary.
Each fluidrachm (teaspoonful) will contain about one grain of valerianate of quinine and one-hundredth of a grain of strychnine.
In former editions of our publication the proportion was one-fiftieth of a grain of strychnine to each fluidrachm. In this edition we conform to the strength established by the National Formulary.
