Derivation of the botanical name:
Centaurea, gets its name from the centaur, Chiron, who is said in mythology to have taught us the healing power of herbs.
cyanoides, cyanos, κυανοϛ, blue steel, azure.
  • The standard author abbreviation Berggren is used to indicate Sven Berggren (1837–1917), a Swedish botanist, explorer and university professor.
  • The standard author abbreviation Wahlenb. is used to indicate Göran Wahlenberg (1780–1851), a Swedish naturalist.
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’s deep blue color symbolizes healthy eyes – hence it became a treatment for eye ailments. (In France, the plant is called casse-lunette, or “break glasses”).
Cornflower is still used in French Herbal medicine as a remedy for the eyes.
