Legend in Greek mythology, Achilles is to use the juice of yarrow to treat foot injuries, so this kind of flower is also called Achilles. Some people call it the herb of wounded soldiers or the herb of knight, so the flower language of yarrow is "treatment". Those who are blessed by this flower have the "nurse" nature of taking care of others.
It is said that Achilles, the greatest hero in Greek mythology, is invulnerable except for his hind tendon. Once, unfortunately, Achilles was injured in the back of his hamstring. Fortunately, Achilles saved his life by healing with yarrow. The hero who was injured by this flower because of carelessness heals the wound, so its flower language is "carelessness". People born on this day often have careless negligence, offend their friends, or be robbed of their love.
