Injections of alum alone, or combined with zinc or oak-bark, are often used with advantage, especially in leu-corrhceal discharges: a strength of about 5 gr. to the ounce is usually sufficient, and plain water should be first injected to cleanse the surface. In the early acute stages, as already mentioned, alum is not suitable, and at any time, too strong a solution applied to the vagina may cause irritation and cramping pain.
