Eyebright is taken by mouth for swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis), allergies, hay fever, and many other conditions, but there is no good scientific evidence to support these uses.
Despite serious risk of infection, some people apply eyebright directly to the eye for conjunctivitis, eyelid swelling (blepharitis), and eye fatigue.
In foods, eyebright is used as a flavoring ingredient.

Uses & Effectiveness
Insufficient Evidence for
- Pink eye (conjunctivitis). Early research shows that about 82% of people with pink eye who use eyebright eye drops have symptoms resolve within 2 weeks. But pink eye usually resolves on its own within 2 weeks. So, it's unclear if eyebright has added benefit.
- Swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis).
- Other conditions.
When applied into the eye: Eyebright is POSSIBLY UNSAFE. It can be contaminated and cause eye infections. It might also cause tearing, itching, redness, vision problems, and other side effects.
Special Precautions and Warnings
When applied into the eye: Eyebright is POSSIBLY UNSAFE. It can be contaminated and cause eye infections. It might also cause tearing, itching, redness, vision problems, and other side effects. Pregnancy and breast-feeding: There isn't enough reliable information to know if eyebright is safe to use when pregnant or breastfeeding. Stay on the safe side and avoid use.
Diabetes: Eyebright might lower blood sugar in some people. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use eyebright.
Surgery: Eyebright might lower blood sugar in some people. In theory, eyebright might interfere with blood sugar control during and after surgical procedures. Stop using eyebright at least 2 weeks before a scheduled surgery.
Medications for diabetes (Antidiabetes drugs) interacts with EYEBRIGHT
Eyebright might lower blood sugar in some people. Diabetes medications are also used to lower blood sugar. Taking eyebright with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.
