Оглавление| Ginger, in moderately fine powder | 6 pounds |
| Capsicum, in fine powder | 2 1/2 pounds |
| Alcohol, a sufficient quantity. |
Mix, moisten the powder with 3 pints of alcohol, and set aside in a suitable vessel for 4 hours. Then pack the powder firmly in a cylindrical percolator, and percolate until 6 pints of extract are obtained. Set this mixture aside and label Percolate No. 1, and continue the percolation with 1 1/2 pints of alcohol mixed with 1 1/2 pints of water. Set the resultant tincture aside, and label Percolate No. 2.
Take oleoresin ginger 5 fluid ounces and add to Percolate No. 1. Then take:
| Oil of lemon | 1 1/2 fluidounces |
| Oil of cinnamon | 1 fluidounce |
| Oil of geranium | 1/2 fluidounce |
| Magnesium carbonate | 8 ounces |
Triturate the oils with the magnesia, add gradually Percolate No. 2, and set aside. Then place Percolate No. 1 in a large bottle, add 3 1/4 pounds of finely powdered pumice stone, and shake at intervals of half an hour for six hours. This being completed, add the mixture of oils, and later 10 pints of water, in quantities of 1/2 a pint at a time, shaking vigorously after each solution. Let the mixture stand for 24 hours, shaking it at intervals, and then pass it through a double filter. Finally add enough water through the filter to make the product measure 24 pints, or 3 gallons.
III.—(To be used in proportion of 3 ounces to 1 gallon of syrup.)
| Ginger, in moderately fine powder | 8 pounds |
| Capsicum, in moderately fine powder | 2 pounds |
| Alcohol, q. s. |
Mix, moisten with alcohol, and set aside as in the preceding formula; then percolate with alcohol until 10 pints of extract are obtained. To this add oleoresin of ginger 3 drachms, and place in a large bottle. Add 2 1/2 pounds of powdered pumice stone, and shake as directed for formula No. 1. Then add 14 pints of water, in quantities of 1 pint at a time, shaking vigorously after each addition. Set the mixture aside for 24 hours, shaking at intervals. Then take:
| Oil of lemon | 1 1/2 fluidounces |
| Oil of geranium | 1/2 fluidounce |
| Oil of cinnamon | 3 fluidrachms |
| Magnesia carbonate | 3 ounces |
Rub these in a mortar with the magnesia, and add 9 ounces of the clear portion of the ginger mixture mixed with 2 ounces of alcohol, rubbing the mixture until it becomes smooth. Prepare a double filter, and filter the ginger mixture, adding through the filter the mixture of oils and magnesia. Finally add enough water through the filter to make the final product measure 24 pints, or 3 gallons.
If these formulas are properly manipulated the extracts should keep for a reasonable length of time without a precipitate. If, however, a precipitate occur after the extract has stood for a week, it should be refiltered.
