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 pyrophosphate of iron, 8 fluidounces.
Elixir of ammonio-citrate of bismuth and pepsin, 8 fluidounces.
Acetic acid, a sufficient quantity.
Triturate the strychnine in a mortar with acetic acid sufficient to dissolve it, and then add the elixirs, having previously mixed them together.
Each fluidrachm (teaspoonful) of the finished elixir contains (subject to remarks which follow) one grain of pyrophosphate of iron, one-half grain each of ammonio-citrate of bismuth and of pepsin, and one-hundredth of a grain of strychnine.
This mixture, like many others we have been led to consider in this work, reminds us of the polypharmacy of olden times, excepting that the constituents are new. In considering it we must accept that the pepsin has no value as a therapeutical agent, unless its action is simply suspended by the alkaline nature of the elixir.
