Hypophosphite of calcium, 384 grains.
Hypophosphite of sodium, 128 grains.
Hypophosphite of potassium, 128 grains.
Citric acid, 30 grains.
Water, 4 fluidounces.
Alcohol, 1/2 fluidounce.
Compound spirit of cardamom, 1/2 fluidounce.
Aromatic elixir, enough to make 16 fluidounces.
The hypophosphites and the citric acid are to be dissolved in the water; then the alcohol, compound spirit of cardamom, and enough aromatic elixir to make sixteen fluidounces are to be added. Filter if necessary. Each fluidrachm contains three grains of hypophosphite of calcium and one grain each of the hypophosphites of sodium and potassium. This formula is similar to that adopted by the National Formulary.
