Supposedly, in ancient times, yarrow was the primary treatment for warriors out in the battlefield because of its ability to heal wounds, slow bleeding, and its antimicrobial properties. It is said to have blood regulating properties as well and was used in relieving the symptoms of menstrual irregularities, such as too little or excessive menses.
