Euphrasia officinalis
Made from eyebright — the little moorland flower whose name has meant 'eye medicine' for two thousand years, and the classical remedy of bland coryza with burning tears.
The whole picture, in one breath
Think of a cold that lives in the eyes: burning, smarting tears that redden the lids, a bland, non-irritating nasal flow, photophobia in the light, and the constant wiping that leaves the cheeks raw — the exact reverse of the onion's pattern. Burning tears with bland nose: that is Euphrasia.
The substance, in plain words
Eyebright is the tiny moorland flower of Europe — its name from the Greeks, who used it for the eyes. Its iridoid glycosides — aucubin above all — are genuinely anti-inflammatory, and eyebright preparations survive in real herbal ophthalmology to this day.
The traditional picture Classical sources
The inner state
- Anxiety with the eye-symptoms. Worry over the light-sensitivity, the constant tears; worse in company.
- Irritability. Cross from the burning and the light.
- Despondency. Gloomy in the recurrent, season-returning states.
The body
- Burning tears, bland nose. The keynote: profuse, acrid, burning tears scalding the lids, while the nasal discharge is bland — the reverse of Allium cepa.
- Photophobia. Intolerance of light, worse in the sun and lamplight; blinking and rubbing.
- Coryza with conjunctivitis. The cold lives in the eyes — the books' great catarrhal-conjunctival remedy.
- Worse light and wind. Sun, wind and bright rooms aggravate; the sufferer seeks the shade.
- Better for open air in the dark. Dark, cool open air relieves the burning.
- Seasonal return. The attacks return with the hay-fever months — the books' seasonal companion.
Modalities (worse and better factors)
| Worse from ⬇ | Better from ⬇ |
|---|---|
| light and sun; wind; warm rooms; evening | dark; cool open air; lying quiet |
Where it acts (organ affinities)
Eyes (tears, conjunctiva, lids), nose and mucous membranes, light-sensitivity.
Where the classical picture comes from
The Greeks named it for the eyes, the medieval herbals kept it, and the proving confirmed the chemistry: burning tears, bland coryza, light-worse. Euphrasia became the classical eye-remedy — and the exact mirror of the onion's cold.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
Eyebright's aucubin is genuinely anti-inflammatory — the iridoid glycoside is documented in laboratory pharmacology, and the plant survives in real herbal eye-preparations in Europe. Modern conjunctivitis is managed with antihistamine drops and, where infection is proven, antibiotics; the flower's two-thousand-year eye career is folk medicine's most consistent.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Allium cepa | Coryza, tears and nose | Allium burns the nose with bland tears; Euphrasia burns the tears with a bland nose — the mirror pair. |
| Apis mellifica | Burning, puffy eyes | Apis is rosy, puffy and thirstless; Euphrasia burning, watery and photophobic. |
| Sabadilla officinalis | Hay fever, sneezing | Sabadilla sneezes in triggered fits; Euphrasia weeps and hates the light. |
| Arsenicum iodatum | Hot acrid catarrh | Ars-iod is hot, restless and glandular; Euphrasia is the eye's own cold. |
