This plant has a valid application as refreshing, astringent and anti-inflammatory effects especially on ocular conjunctiva. It is a decongestant and anti-reddening of the skin, to which is added a strong tonic action.


The name comes from an ancient Greek word ” kyanos ” or ” κύανο “, indicating a blue substance, with reference to the prevailing color of the flowers. The combined name Centaurea cyanus, however, has been suggested by the scholar John Hill in reference to two episodes of Roman mythology: the first says that the goddess Flora was in love with a young man named Cyanus discovering it lying dead in a field of cornflowers gave the flowers the boy’s name, while the second comes from the name of the centaur Chiron, who was wounded in the foot by a poisoned arrow and was cured with the juice taken from this flower.
The Emperor William I chose the cornflower as a symbol of his family to remember when, a boy, wove garlands of this flower as a single game during the escape from Napoleonic troops.
The petals of cornflower are used to extract the color blue for the realization of watercolors.
