This easily recognised plant may be used wherever a gentle diuretic is called for, for instance in water retention due to kidney problems. As an astringent it will prove effective in the treatment of diarrhoea, wounds, nose bleeds and other conditions. It has specific use in the stimulation of the menstrual process whilst also being of use in the reduction of excess flow. The New Holistic Herbal by David Hoffmann Pg. 232
