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 matico, 3 fluidounces.
Fluid extract of buchu, 1 fluidounce.
Fluid extract of cubebs, 1 fluidounce.
Simple elixir, 16 fluidounces.
Carbonate of magnesium, a sufficient quantity.
Mix the fluid extracts, and evaporate the mixture, at a temperature of about 150 F., to one-half its bulk. Triturate this with a sufficient amount of carbonate of magnesium to form a creamy mixture, then gradually stir in the simple elixir, and filter. The fluid extracts for the foregoing preparation should be made with alcohol of specific gravity 0. 820. The proportions and ingredients of this elixir, and upon which we have based our formula, were given in the Druggists' Circular, 1880.
Each fluidrachm of the finished elixir will contain such an amount of the properties of about eleven minims of fluid extract of matico and three and one-half minims each of buchu and cubebs as will dissolve in the menstruum. Since, in our opinion, strong alcohol only will perfectly extract the medicinal principles of these drugs, the actual value of this elixir is very much less than that of an equivalent amount of the original fluid extracts, and its use by the physician must be unsatisfactory.
