Yarrow, also known as old man's pepper, devil's nettle, sanguinary and nosebleed plant, is a perennial, flowering plant in the Asteraceae family, which includes daisy, aster, sunflower, chrysanthemum and marigold. The herb naturally occurs most of Europe, North America and parts of Asia. Yarrow’s botanical name, Achillea millefolium, and one of its common names, soldier's woundwort, originate from the legend of Achilles, the Greek hero of the Trojan War who reputedly distributed the plant to wounded soldiers at risk from blood loss. Today, the fern-like leaves and colorful flowers are dried for use in floral crafts and to make tinctures, infused oils and salves.
