Medicinal Properties of Cornflower

Cornflower has been used in folk medicine for centuries, particularly in European herbal traditions. It offers gentle yet effective support for several body systems.

🌿 Diuretic and Detoxifying

Cornflower helps support healthy kidney and bladder function. It gently stimulates urination, assisting the body in eliminating excess fluids and toxins. It's often included in cleansing herbal blends.

🌿 Anti-inflammatory

Thanks to its high content of flavonoids and anthocyanins, cornflower has anti-inflammatory properties. It may help reduce mild internal inflammation (e.g. in the digestive system) and soothe irritated skin or eyes when applied externally.

🌿 Eye Health Support

Perhaps its best-known use is for tired, irritated, or puffy eyes. Cornflower infusion can be used as a gentle eye rinse or compress to reduce redness, soothe inflammation, and ease eye fatigue – especially useful for those working long hours on screens.

🌿 Mild Antibacterial Action

Cornflower may support the immune system by gently inhibiting the growth of some bacteria. It’s often added to immune blends and seasonal herbal teas.
