Does Eyebright Work?

Eyebright, or Euphrasia nemorosa, has been used for centuries to treat a wide variety of ailments affecting the eyes. As with all herbs, there is always some dispute regarding their effectiveness; however, anecdotal evidence indicates that eyebright in herbal and homeopathic form is a highly effective treatment when used according to the directions of a health practitioner familiar with its properties. Because it can cause side effects, contact your health provider before using this herb.

Description

Eyebright is a small plant with tiny white or lavender flowers and dark purple veins. The historical origin for its use as an eye treatment began after it was noticed that the flowers appeared to have a bloodshot appearance, similar to that of the eye when it is inflamed, notes the NYU Langone Medical Center. The decision to use it as an herbal treatment for the eye is based on what is known as the "doctrine of signatures," a medieval philosophy stating that a substance's medicinal properties reflect its appearance. Although this may seem far-fetched to some people, it has actually proved to be accurate in certain herbs, based on anecdotal observations over time.

Uses

As an herb, eyebright has shown its effectiveness in the treatment of diseases and conditions affecting not only the eyes, but also the sinuses and upper respiratory tract. It can be used for treatment of cataract, conjunctivitis or pink eye, blepharitis or pus-like discharge of the eyelids, sinusitis and respiratory congestion with nasal discharge, itching and irritation of the eyeball, according to Brandeis University. Mercer University reports that the herb has astringent and anti-inflammatory properties on mucous membranes, and antibiotic properties useful in killing bacteria that cause eye infections. Eyebright makes an excellent treatment for hay fever or allergic reactions, where there is lots of tearing, sneezing, and runny noses.

Homeopathic Use

Eyebright is also available as a homeopathic remedy called Euphrasia. It is generally milder than when eyebright is used as an herbal treatment. Euphrasia is indicated for inflammatory conditions of the eye that produce profuse, burning tears, according to homeopath Dr. William Boericke in his book, "Materia Medica with Repertory." The person needing euphrasia generally is better in the open air. There may be other symptoms accompanying the eye problems, such as congestion in the sinuses, severe headache and coughing with a great deal of phlegm and expectoration. The Euphrasia eye discharges are always excoriating or burning, while nasal discharges tend to be non-irritating. This is a keynote indicating the need for this remedy. Like its herbal counterpart, Euphrasia is an excellent remedy for those suffering from allergies and hay fever, as long as the patients' symptoms indicate its use. Euphrasia is available over-the-counter without a prescription from most health food stores. Consult a homeopath for dosage guidelines.

Precautions

Because eye treatment generally requires that a sterile substance be used to protect the eye, it is recommended that you seek professional guidance if you want to use this herb to treat your eye disease. Although it is considered safe when used according to directions, side effects may still occur, and medical supervision is necessary.
