Yarrow carries the name Achillea because the Greek God Achilles in mythology is storied to have given the plant to his troops to stop bleeding in battle. Unfortunately, it didn't stop the bleeding when he hurt his own heel, and he died from his wounds. The modern terms "Achilles tendon" and "Achilles heel" originate from this myth.
Yarrow sticks (dried Yarrow stems) were used by the ancients for I Ching divination for centuries. Yarrow was considered a spiritual plant that was highly suitable for for this purpose. Sadly in modern times, coins have largely replaced Yarrow Sticks for this type of divination..
