P. E.—Green pistils or stigmata.
N. H.—Temperate zones.
Properties: Diuretic, demulcent.
Use: Useful in uric acid and phosphatic gravel. We also think of it in cystitis, retention of urine, vesical catarrh, edema due to weak heart and in cases where an excess of urates and phosphates is excreted with the urine. It has a soothing effect on the whole urinary tract. As it is only mildly demulcent and diuretic it is not active enough where powerful remedies are required, but it is a valuable adjunct in such cases.
