- Dosing considerations for Eyebright.
Eyebright is taken by mouth to treat swollen (inflamed) nasal passages, allergies, hay fever, common cold, bronchial conditions, and inflamed sinuses (sinusitis). It is also used for cancer, coughs, "pink eye" (conjunctivitis), earaches, epilepsy, headaches, hoarseness, inflammation, jaundice, runny nose, skin ailments, and sore throat.
Despite serious risk of infection, some people apply eyebright directly to the eye in the form of a lotion, poultice, or eye bath to treat a variety of conditions including conjunctivitis; inflammation of the eyelids at the edge of the lashes (blepharitis); eye fatigue; inflammation of the blood vessels, eyelids and conjunctiva; and for "glued" and inflamed eyes. Eyebright is also applied to the eyes to prevent mucous and mucous membrane inflammation of the eyes.
In foods, eyebright is used as a flavoring ingredient.
Historically, eyebright has been used in British Herbal Tobacco, which was smoked for on-going lung conditions and colds.
