Specific Indications.—Irritation of urinary passages; pain in the back; frequent and difficult or painful urination; gravel; discharges of mucus and blood from the urethra.
Action and Therapy.—A mild diuretic with slightly aperient properties, and a demulcent of value in irritated conditions of the genito-urinary organs. It is of special value to lessen the frequency and pain of urination—a remedy for dysuria and strangury. It may be used when inflammation is present, and is highly valued in chronic cystic irritability, cystitis, pyelitis, incipient nephritis, prostatitis, and in any condition in which an excess of mucus, pus, or blood is passed in the urine. Indirectly it acts as an alterative by washing away broken-down material by way of the renal organs.
