Yellow cinchona bark, 3 troyounces.

Gentian, 1 troyounce.

Bitter orange peel, 1 troyounce.

Alcohol, 16 fluidounces

Cinnamon water, 8 fluidounces.

Reduce the drugs to a coarse powder and prepare a tincture by percolation, using a mixture of the alcohol and cinnamon water. This preparation is a modern tincture, although it was once classed with elixirs. The German Pharmacopoeia (1872) recognizes, under the above name, the compound tincture of cinchona.
