This agent should be freely employed where there is excess of uric acid; where the "brick dust" deposit is marked; where the extreme and nauseating backache suggests that the crystalline constituents of the urine are not well dissolved and washed out of the tubules; or where there is renal sand or gravel in the bladder; where the urine is dark and heavy, and there is irritation, causing congestion of the kidneys, which in some cases induces hemorrhage; where precipitated solids irritate the bladder, and induce cystitis with thickening of the walls, and formation of pus. An infusion of epigaea freely drunk in these cases will relieve the entire train of symptoms, inducing a grateful sense of relief from irritation and distress. ..."
