Eyebright (Euphrasia officinalis) is a type of medicinal plant that has been used since the 14th century for its use in eye-related healing properties. Eyebright has showed evidence of reducing inflammation in the eye caused by blepharitis and conjunctivitis. It has been used as an eyewash, eye drops, or plant infusions taken internally for ophthalmic use. Specific applications studied in poultry include:
Eye healing: : Infected eyes can be treated with eyebright tea in the following forms:
