Historical record

Named after Achilles, who according to the Iliad used yarrow to treat his wounded Myrmidon warriors at the siege of Troy. Dried yarrow stalks have been used for over 3,000 years in China to cast the I Ching.

Folklore and mythology

Plucked with the left hand under the full moon while reciting charms to dream of one's future spouse. Tied over baby cradles to shield against fairy changelings. Known as 'Soldier's Woundwort' and 'Devil's Nettle'.

Sacred to Achilles and Chiron the Centaur. In Chinese Taoist lore, yarrow stalks act as sacred conduits connecting heaven, earth, and human destiny during hexagram divination.

Other accounts say Chiron taught Achilles its wound-closing virtues, and Taoist masters selected 50 straight stalks for I Ching divination.

Tradition: Greco-Roman & Chinese Taoism Associated figures: Achilles & Shennong / I Ching Sages
