Yarrow: Medical Uses
Yarrow encourages perspiration, appetite, and strength.
Yarrow was called “soldiers’ woundwort” because the leaves were taken onto the battlefield and applied to stop wounds from bleeding. Yarrow compresses were used for hemorrhoids. In folklore, fresh yarrow root was used as an anesthetic for surgery. Fresh roots or leaves were also mashed in whiskey and used for toothache.
Yarrow grows wild in meadows and on roadsides in North America. The flower heads grow in clusters of different-colored varieties of white, yellow, orange, and bright red. White yarrow is the variety most often used medicinally. Yarrow repels ants, flies, Japanese beetles, and termites.
