Bitters

Bruise an ounce of gentian root, and two drams of cardamom seeds together: add an ounce of lemon peel, and three drams of Seville orange peel. Pour on the ingredients a pint and half of boiling water, and let it stand an hour closely covered: then pour off the clear liquor, and a glass of it taken two or three times a day will be found an excellent bitter for the stomach.

Or slice an ounce of gentian root, and add half a dram of snakes’ root bruised, half a dram of saffron, three quarters of a dram of cardamom seeds, and the same of cochineal bruised together, and the peel of three Seville oranges. Steep the ingredients in a pint of brandy fourteen days, shaking them together frequently; then strain the tincture through a piece of muslin, and a tea-spoonful in a glass of wine may be taken two or three times a day.
