Of value in incontinence of urine in children and old people, the result of atony and relaxed condition of the bladder and urinary apparatus. In enuresis caused by enlarged prostate gland. In spermatorrhea the result of masturbation or over-indulgence, especially if there is depression of the mind in these cases.

As it has a positive tonic effect on the muscular walls and mucous membranes of the bladder and urinary apparatus it is a good remedy where women cannot hold their urine on coughing or sneezing.
