In modern medicine, Cornflower does appear to be of benefit externally and likely has antiseptic properties, making it worth a try for cuts, scrapes, and bruising of the skin. It is also fairly well-known by herbalists as a remedy for conjunctivitis, eye swelling, puffiness, and pain related to the eye area. The petals are also taken as a bitter tonic and stimulant, improving digestion and possibly supporting the liver as well as improving resistance to infection.
