Eyebright Herb
A traditional herbal remedy used for centuries to soothe irritated, inflamed, and tired eyes.
Also known as: Euphrasia officinalis
Overview
Eyebright is a small flowering plant whose use in traditional European herbalism for eye ailments dates back to the Middle Ages. Its name, Euphrasia, is of Greek origin and means "gladness," referring to the joy one would feel if their sight was restored. It contains flavonoids, tannins, and iridoid glycosides (like aucubin) that are believed to have anti-inflammatory, astringent, and antioxidant properties, making it a popular ingredient in herbal eye drops and washes.
Key Benefits
Soothes Irritation and Redness
Traditionally used to relieve symptoms of conjunctivitis (pink eye), blepharitis (eyelid inflammation), and general eye irritation from allergens or fatigue.
Anti-inflammatory Action
The compound aucubin has demonstrated anti-inflammatory effects, which may help reduce swelling and discomfort in the eyes.
Astringent Properties
The tannins in eyebright can help tighten the mucous membranes of the eye, reducing discharge and creating a protective barrier.
