The first traces of the use of dyer's woad by man date back to prehistoric times, and the species was subsequently cultivated in various parts of Europe in the Middle Ages to produce an indigo blue dye from the maceration of its leaves. Isatis tinctoria's antiseptic, antibacterial and anti-inflammatory properties have been known since Greco-Latin antiquity. The plant is still used in traditional Chinese medicine to treat minor wounds.
