This is a valuable remedy in diseases of the urinary apparatus. It gives tone to the kidneys, improving their functional activity, and thus tends to arrest the formation of urinary deposits and calculi. We do not believe, as Dr. J. W. Butler stated, that it will cure stone in the bladder, though it may prove prophylactic. It relieves irritation of the bladder and urethra, and hence proves serviceable in cases of gravel. It also exerts an influence upon the respiratory mucous tract, relieving bronchial irritation.
