Strychnine, 1 1/2 grains.
Simple elixir, 16 fluidounces.
Valerianic acid, a sufficient quantity.
Powder the strychnine in a mortar and add two fluid ounces of simple elixir, and then enough valerianic acid to effect the solution of the strychnine. Lastly, add the remainder of the simple elixir.
The formula is essentially that presented by Prof. C. Lewis Diehl to the Louisville College of Pharmacy, excepting that we have made the proportion of strychnine conform to that established by the National Formulary.
Each fluidrachm (teaspoonful) of the finished elixir contains one hundredth of a grain of strychnine.
