Euphrasia has traditionally been used for the symptomatic relief of conjunctivitis and symptoms such as dry, itching, gritty feeling, acrid tears and light sensitivity. This is primarily an eye and sinus remedy. Made from the herb Eyebright, it is often indicated when the membranes of the eyes, nose and sinuses are inflamed, such as in hay fever, sinusitis, or conjunctivitis which produce watery secretions that are acrid.
