Fluid extract of boldo, 4 fluidounces

Simple elixir, 12 fluidounces

Alcohol, 2 fluidounces

Carbonate of magnesium, a sufficient quantity.

Triturate the fluid extract of boldo with carbonate of mag-nesium sufficient to produce a creamy mixture, then gradually add the simple elixir, filter, and add the alcohol.

Verne recommended an elixir of boldo in the Pharmaceutical Journal and Transactions, but, as the virtues of boldo are imperfectly extracted by an aqueous liquid, we do not admire such a preparation. According to this formula each fluidrachm should contain the active principles of seven and one-half minims of fluid extract of boldo. But, as a matter of fact, that amount will not dissolve in that quantity of the menstruum, the excess remaining in the filter paper.
