Medicinal Uses

A. millefolium was used in traditional medicine, in part due to its astringent properties and the mild laxative effect of its leaves. It was used in ancient times to heal wounds and stop bleeding, and in the 16th century, the crushed leaves were used to stop nosebleeds. North American varieties were traditionally used by many Native American nations. The Navajo considered it a "life medicine" and chewed the plant for toothaches and used its infusions for earaches. The Miwok in California used the plant as an analgesic and head cold remedy. Native American nations used the plant for healing cuts and abrasions, relief from earaches and throat infections, as well as for an eyewash. Yarrow was used by Plains indigenous peoples to reduce pain or fever and aid sleep. Some Ojibwe people used a decoction of yarrow leaves on hot stones and inhaled it to treat headaches, or applied decoctions of the root onto skin for its stimulating effect.

Known Hazards

Yarrow can cause allergic skin rashes. According to the American Society for the Prevention of Cruelty to Animals, yarrow is toxic to dogs, cats, and horses, causing increased urination, vomiting, diarrhea and dermatitis. When consumed by cows, an unfavorable flavor is given to their milk.
