Euphrasia officinals

Description:Euphrasia is particularly of use to us as a medicine acting on mucous membranes, especially the conjunctiva and the nasal mucous membrane. It has long been known as a remedy in affections of the eyes. First it produces an inflammation of the eyelids, a blepharitis. The eyelids become reddened and injected, particularly on their inner surface. They become puffed, dark red or red at least, ulceration takes place, giving us a discharge which is thick and excoriating. The tears themselves are profuse and excoriate the cheeks. There is marked photophobia ; the patient cannot bear sunlight, but even more objectionable to him is artificial light. It has been urged by some physicians that it is "splitting hairs" in attempting to differentiate between aggravation from sunlight and that from artificial light. I cannot see where this objection has any force, for sunlight and artificial light are very different in their compositions.
