Eyebright (Euphrasia officinalis)

Tier 3 — weak evidence · Eye health · Allergies · Conjunctivitis

A traditional European herb used since the Middle Ages for eye conditions. A few small European trials found eyebright eye drops reduced redness and irritation from conjunctivitis. However, no rigorous modern trials support oral supplementation for vision or eye health. EMA classifies it as a traditional herbal medicine. Very safe when used as directed. Do not apply homemade preparations to the eye.

Dose: 250–500 mg/day oral extract or commercial eye drops; no evidence oral form helps eye conditions
