Fluid extract of yerba santa, 2 fluidounces.

Simple elixir, 14 fluidounces.

Alcohol, 1/2 fluidounce.

Carbonate of magnesium, a sufficient quantity.

Triturate the fluid extract of yerba santa 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.

This elixir has been recommended as a vehicle for administering quinine, and is said to disguise its bitterness. A process was devised by Mr. Jas. S. McCleary whereby aromatics were added, and which we give in substance under compound elixir of yerba santa. Yerba santa contains a peculiar sweet astringent principle which may precipitate the quinine, thus rendering it insoluble. Care should be taken that the mixture be not filtered after the addition of the quinine.
