Yarrow is used against colds, cramps, fevers, kidney disorders, toothaches, skin irritations, and hemorrhages, and to regulate menses, stimulate the flow of bile, and purify the blood.


Yarrow is native to Europe and Asia and has been naturalized in North America. Its use in food and medicine dates back to the Trojan War, around 1200 B.C. In classical times, yarrow was referred to as "herba militaris" because it stopped wound bleeding caused by war. Yarrow leaves have been used for tea, and young leaves and flowers have been used in salads. Infusions of yarrow have served as cosmetic cleansers and medicines. Sneezewort leaves (A. ptarmica) have been used in sneezing powder, while those of A. millefolium have been used for snuff. Yarrow has been used therapeutically as a strengthening bitter tonic and astringent. Chewing fresh leaves has been used to relieve toothaches. Yarrow oil has been used in shampoos for a topical healing effect.
