Achilles, the great warrior in the ten year Trojan War staunched the bleeding wounds of his soldiers with yarrow. He also tried to stop the bleeding wound in his heel, but alas, he died from his wound. Yarrow was called the military herb by the Ancients. We get the words “Achilles tendon” from this incident in mythology. Yarrow is used as “hops” in beer, as snuff, and as an antiseptic.
