Syrup of Curaoa, 120 minims.
Orris root, powdered, 30 grains.
Deodorized alcohol, 4 fluidounces.
Citric acid, 50 grains.
Syrup, 8 fluidounces.
Purified talcum, 120 Grains.
Water, enough to make 16 fluidounces.
Mix the syrup of Curaoa with the alcohol, add the orris and purified talcum and three fluidounces of water. After twelve hours, agitating occasionally, pour the mixture on a wetted filter, returning the first portions of the filtrate until it runs clear, and follow the filtrate with enough water to make eight fluidounces in all. In this dissolve the citric acid, and finally add the syrup. This elixir is practically identical with that of the National Formulary, the proportions of ingredients being the same.
