Parts Used & Where Grown
In the wild, European eyebright grows in meadows, pastures, and grassy places in Bulgaria, Hungary, and the former Yugoslavia. Eyebright is also grown commercially in Europe. The plant flowers in late summer and autumn. The whole herb is used in herbal medicine.
How It Works
While there are many chemicals that may be active in eyebright, none of them has been proven to have any effect on eye inflammation or irritation. Some herbal texts suggest that the astringent actions of eyebright may reduce eye irritation while others suggest that eyebright may also have antibacterial actions topically. To date, there are no clinical studies to support or refute these proposed actions.
