The story…

Cornflower is native to Europe and has been naturalized in many parts of the world, including North America and Australia. However, it is endangered in its natural habitats by intensive agriculture, particularly because of the over-use of pesticides. It can be found sporadically on roadsides.


Tired or inflamed eyes, conjunctivitis

Cornflowers have an antioxidant and protective effects on tissues, as well as antiallergic and anti-inflammatory. They are useful to decongest tired (particularly due to over-exposition to screens), swollen or irritated (for example because of pollution or an allergic reaction) eyes; or in the case of conjunctivitis. Apply an infusion (carefully filtered) on the closed eyelid, during approximately 10 minutes.

They also have an astringent effect on the eyelid and the skin bellow the eye and can be used as a make-up remover.


Conjunctivitis is contagious: be cautious with hygiene rules and wash your hands and the utensils after using. In case of persistent symptoms or if you have any doubts, consult a doctor.
