Yarrow has a flat-topped flower cluster consisting of numerous minute white flowers. The leaves have a fern-like appearance and are intricately divided. This plant has a strong scent.
Yarrow has been used to stop bleeding of wounds and cuts, as a poultice for burns and open sores, to cure fevers and colds, and alleviate toothaches.
Indiginous Americans believed that it acted as a disinfectant and promoted healing. Modern pharmacists have extracted an alkaloid chemical from the plant which reduces the clotting time of blood.
