Overview
Eyebright is a small semi-parasitic wildflower whose striped flowers resemble an eye, and in the tradition of the Doctrine of Signatures, it has been used specifically for eye conditions for over 700 years. The tannins and aucubin iridoid provide anti-inflammatory and astringent properties that reduce mucous membrane inflammation in the eyes and sinuses. The EMA recognizes traditional use for conjunctivitis, eye strain, and hay fever.
Traditional Use
Documented in European herbal medicine from the 13th century onward. Hildegard von Bingen, Culpeper, Fuchs, and virtually every major European herbalist included Eyebright for eye conditions. 17th century diarist Samuel Pepys mentions drinking eyebright wine for sore eyes. Milton referred to the archangel Michael using 'euphrasine and rue' to restore Adam's sight. Used across European folk medicine for all eye complaints — conjunctivitis, styes, tired eyes, and cataracts.
Key Active Compounds
Aucubin (Iridoid Glycoside)
The primary active compound — anti-inflammatory, antiviral, and antimicrobial. Reduces mucous membrane inflammation in both eye and sinus tissues.
Tannins (Gallotannins)
Astringent compounds that reduce secretions, tighten mucosal tissue, and provide antimicrobial activity. Responsible for the eye-drying, discharge-reducing effect in conjunctivitis.
Quercetin and Rutin
Flavonoids providing anti-inflammatory, anti-allergic (mast cell stabilization), and antioxidant protection. Particularly relevant for allergic conjunctivitis and hay fever.
Evidence-Based Benefits
Conjunctivitis and Eye Inflammation
Traditional useClassic herbal eye remedy — the astringent tannins and anti-inflammatory aucubin reduce eye redness, discharge, and irritation. Used as an eyewash (always sterile preparation) or oral tea.
Hay Fever and Allergic Rhinitis
Traditional useExcellent herb for hay fever affecting eyes and sinuses. Quercetin and rutin stabilize mast cells, reducing histamine-mediated symptoms. Particularly good for the classic watery itchy eyes of allergic rhinitis.
Sinus Congestion and Catarrh
Traditional useTraditional astringent for excessive nasal and sinus discharge. Reduces mucous membrane hypersecretion and inflammation.
Common Preparation Methods
Eyebright Tea (Internal)
Steep 1–2 teaspoons dried eyebright in 1 cup boiling water for 10 minutes. Strain thoroughly.
Dosage: 3 cups daily during active eye or sinus symptomsThe internal use is the primary approach in modern clinical herbalism — the anti-inflammatory compounds work systemically on all mucous membranes.
Eyewash (External — Use with Caution)
Make a strong, STERILE decoction (boil for 10 min, then filter through sterile gauze). Cool to comfortable temperature. Use a sterile eye cup to bathe the eye.
Dosage: Wash each eye 2–3 times dailyCRITICAL: sterility is essential — contaminated eye preparations can cause serious eye infections. Many herbalists prefer to avoid the eyewash and use tea internally instead. If any irritation increases, discontinue immediately.
