An infusion of it is reputed a valuable remedy in reproductive disorders of the nervous and hysterical, impaired digestion, chronic diarrhoea, intermittent fevers, etc. As a diuretic, it has been beneficially used in urinary affections, gonorrhoea, gleet, etc. Both populus and populin have a decided affinity for the genito-urinal tract.
