Yarrow's flowering aerial parts appear throughout European materia medica. Historical names such as herba militaris reflect battlefield wound lore, while later preparations were used for appetite, mild spasmodic digestive complaints, menstrual discomfort, and minor superficial wounds. EMA recognizes defined traditional uses based on long-standing practice; this does not establish efficacy for bleeding, infection, or serious illness. Yarrow's historical wound and digestive uses do not establish modern efficacy.

Yarrow's battlefield name and tough, finely divided foliage support modern themes of courage, protection, boundaries, and healing symbolism. Its historical use as stalks in Chinese divination and later European love lore add divination and relationship correspondences.
