Take four ounces of the root, slice it down, put the slices into four pints of water, and simmer for four hours. Take out the sarsaparilla, and beat it into a mash; but it into the liquor again, and boil down to two pints, then strain and cool the liquor. Dose - a wine-glassful three times a-day. Use - to purify the blood after a course of mercury; or indeed whenever any taint is given to the constitution, vitiating the blood, and producing eruptive affections.
