Diuretic Syrup.
Take Arsmart-water 1 quart; Prunella-stone 2 ounces; white Sugar 2 pound; boil it up to a Syrup.
It has the same Virtues with the Diuretic Nitrous Julep.
If the Spirit of Vitriol, Nitre, Salt, Oil of Sulphur, or the like intense Mineral Acids, be poured upon Nitre; 'twill raise a smoak like Aqua fortis: Therefore care should be taken, that none of these Chymical Acids be mixed with this Syrup, or any other Nitrous Medicine, because they'll produce such a corrosive sharpness, as will be extreamly noxious to the Stomach and Bowels.
