Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Cornflower (Centaurea cyanus) has a long history of traditional use, particularly in European herbal medicine, for supporting eye health. It has been used in folk remedies as an eyewash or compress to soothe mild eye irritations, conjunctivitis, and puffiness. The petals are often steeped in water to create an infusion, which is then applied externally. This traditional application is reflected in the plant’s common names, such as "Bachelor’s Button" and "Bluebottle," and in its inclusion in historical pharmacopeias for eye care.

However, there is limited modern scientific evidence to validate these uses. The soothing effect is likely due to the presence of flavonoids and anthocyanins, which have mild anti-inflammatory and antioxidant properties. Nonetheless, clinical studies evaluating the safety and efficacy of cornflower preparations for ocular health are lacking. As a result, its use for the eyes remains mainly supported by tradition rather than robust scientific data. While generally considered safe for topical use in the absence of allergies, cornflower should not replace evidence-based treatments for eye conditions. In summary, cornflower’s reputation for supporting the eyes is primarily rooted in traditional herbal practice, with minimal scientific corroboration.
