Cornflower - Centaurea cyanus If your answer is NO.


Cornflower has a long history of herbal use, though it is seldom employed nowadays. In France it is still used as a remedy for tired eyes, but opinions differ as to its efficacy. Traditionally it is said to work best on blue eyes, whilst Plantago major (great plantain) was used for brown eyes. The dried flowers are antipruritic, antitussive, astringent, weakly diuretic, emmenagogue, ophthalmic, very mildly purgative, and tonic. An infusion can be used in the treatment of dropsy, constipation, or as a mouthwash for ulcers and bleeding gums. This infusion is also taken as a bitter tonic and stimulant, improving the digestion and possibly supporting the liver as well as improving resistance to infections. A water distilled from the petals was formerly in repute as a remedy for weak eyes and a soothing lotion for conjunctivitis. The seeds are used as a mild laxative for children. A decoction of the leaves is antirheumatic. Antifungal. Source:
