Eyebright (Euphrasia officinalis) is an annual plant that grows wild in meadows, grassy areas, heaths, and pastures of Britain, northern and western Asia, North America, and Europe.
Eyebright is beneficial in the treatment of coughs, colds, allergies, sinusitis, hay fever, earaches, headaches, jaundice, throat and bronchial congestion, hoarseness, flu, and sinus inflammation.
If a tincture solution of eyebright is placed on the eyes, tearing, itching, reddening, and swelling of the eyelids may develop because of the alcohol in the tincture.
Although a stimulating astringent and tonic that has an effect on the mucous membranes, eyebright is primarily used as an eye bath to treat problems such as conjunctivitis, sties, strains, nervous and muscular vision disorders, and catarrh.
In folk medicine eyebright was a remedy for eye infection and irritation, abnormal growths, coughs, hoarseness, jaundice, earaches, allergies, skin conditions, and gastrointestinal difficulties.
The efficacy and tolerability of the eyebright eye drops were evaluated by the patients and doctors and were deemed as "good" to "very good" in more than 85% of cases.
