Yarrow \Yar"row\, n. [OE. yarowe, yarwe, [yogh]arowe, AS. gearwe; akin to D. gerw, OHG. garwa, garawa, G. garbe, schafgarbe, and perhaps to E. yare.] (Bot.) An American and European composite plant ({Achillea Millefolium}) with very finely dissected leaves and small white corymbed flowers. It has a strong, and somewhat aromatic, odor and taste, and is sometimes used in making beer, or is dried for smoking. Called also {milfoil}, and {nosebleed}.
A curandero known as Don Antonio said he made his reputation in 1926, at age 19 or 20, after a villager was hit by a truck and suffered a nosebleed that would not stop.
