Cornflower’s medicinal prosperities were first mentioned in the 12th century writings of Hildegard of Bingen (1098-1179) and later the herbalist, Pierandrea Mattioli (1501-1577) recommended it on the basis of the Doctrine of Signatures, a theory according to which a plant's appearance indicated the ailments it would cure.

Cornflower is still used in French Herbal medicine as a remedy for the eyes. Location:Carmel, Hurshat Ha'arbaim, חורשת הארבעים Location:Carmel, Hurshat Ha'arbaim, חורשת הארבעים
