What is eyebright?

Eyebright is a plant also known as Aufraise, Augentrostkraut, Casse-Lunettes, Eufrasia, Euphraise, Euphrasia, Herbe d'Euphraise, Luminet, and other names.

Eyebright has been used in alternative medicine as an aid in treating nasal congestion, sinus pain, cough, breathing problems and other symptoms of allergies or the common cold. However, eyebright use in these conditions has not been proven with research to be effective.

Other uses not proven with research have included using eyebright in an eyedrop to treat "pink eye" (conjunctivitis). Eyebright is thought to be possibly unsafe when applied directly to the eye.

It is not certain whether eyebright is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Eyebright should not be used in place of medication prescribed for you by your doctor.

Eyebright is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Eyebright may also be used for purposes not listed in this product guide.
