For the same reason as fixt Salts, sometimes also volatile Salts are given with good success to move Urine in a sourish distemper of the Blood, to wit, forasmuch as its Particles when admitted into the Blood destroy the predominancy of the fluid Salt in it; so that the Blood recovering its due mixture, and being freed from coagulations and fluxions, drinks up again what Serum is extravasated, and conveys what is superfluous, to the Reins to be sent forth by the Ureters. But we may note withal, that Medi∣cines prepar'd of a volatile Salt, having particles somewhat fierce in operation and instigating, when they correct the Crasis of the Blood, dispose what there is superfluous of Serum to be discharg'd, sometimes by Sweat as much as by Urine. In this order of Diu∣reticks, not only the bare volatile Salt drawn forth of Animals and Minerals ought to be numbred; but likewise the integral parts of Animals and Vegetables, such as are the Powders and Extracts of Insects and Vegetables of a smart nature.
