(from δια, by, and υγεια, urine), medicines which provoke a discharge by urine.

Such is water drank plentifully; white wine drank in a morning; alkaline salts of all kinds; sea salt, sal gemmar, nitre, borax, alum, tartar, sal ammoniac, whey, four milk, lemon juice, &c. Aqueous liquors are generally diuretic, especially if mixed with salt, and drank cold. Fermented liquors are the least diuretic of all; and the less so, as they are the fatter. Sharp thin sour wines, Rhenish, &c., as also acid spirits of vinegar, salt, sulphur, alum, vitriol, &c., asparagus, bitter almonds, smallage, eryngium, eupatorium, sassafras, &c., are all diuretics.
