Yarrow (Achillea millefolium) is an attractive plant with dainty, serrated leaves topped by clusters of tiny petals. The plant is native to Europe, flourishing in neglected areas such as rocky hills and fields; however, it can be found in the U.S. Historically, the legendary Achilles is said to have placed yarrow root into the wounds of the warriors accompanying him in battle. That is where the plant obtained its Latin nomenclature. Yarrow root is a potent antiseptic with natural astringent powers. It is also said to promote improved circulation to the scalp while softening both skin and hair as an effective emollient. The calming, herbal smell of yarrow has also been associated with encouraging healthy hormone function while increasing a person’s sense of alertness.
