Elixir of calisaya (alkaloidal), 14 fluidounces.

Distilled water, 2 fluidextracts

Pyrophosphate of iron, 256 grains.

Dissolve the pyrophosphate of iron in the distilled water, add the elixir of calisaya, and filter if necessary. If not neutral in reaction, bring it to a neutral condition by addition of either acetic acid or ammonia water.

Each fluidrachm (teaspoonful) of the finished elixir contains two grains of pyrophosphate of iron and represents about four grains of officinal: calisaya bark. The proportion is that recommended by the American Pharmaceutical Association, 1875.

In 1862 Mr. James T. Shinn published (American Journal of Pharmacy) a process for making the above elixir, employing crude materials upon the principle of Mr. Taylor's elixir of calisaya. In speaking of it Mr. Shinn uses the following language: "Among the pharmaceutical novelties recently brought to the notice of physicians, this preparation of iron, cinchona, and brandy is one of the most agreeable, and possibly may prove very popular with patients." The result proves Mr. Shinn's surmise to have been correct, although the original preparations have been replaced with those more pleasing to the eye.
