Take wormwood, 8 ounces; juniper berries, 4 ounces; cinnamon, 1 ounce; coriander, 1 ounce; ginger root, 1 ounce; nutmeg, one half ounce; peels of bitter orange, one half ounce.
Many variations can be made by using the wormwood and bitter orange peel, calisaya bark, wild cherry bark, calamus root, quassia, gentian root, and employing different other drugs, such as lemon peel, peppermint, etc., or the respective oils, essences or tinctures.
This essence is prepared from the oils: Oil of calamus, 1 ounce; oil of orange, 1 ounce; oil of wormwood, 1 fluid drachm; oil of anise, 1 fluid drachm; oil of cloves, 2 fluid drachms; oil of cinnamon, 2 fluid drachms. Mix, cut these oils as generally directed with pumice, etc., dissolve in 22 ounces of alcohol of 95 per cent., and dilute with 22 fluid ounces of water to obtain 44 fluid ounces of essences.
