Overview

Overview Information

Eyebright is a plant. The parts that grow above the ground are used to make medicine.

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.

How does it work?

The chemicals in eyebright might act as astringents and kill bacteria.

Uses

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.
  • Allergies.
  • Colds.
  • Coughs.
  • Earaches.
  • Headache.
  • Swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis).
  • Other conditions.
More evidence is needed to rate the effectiveness of eyebright for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Eyebright is LIKELY SAFE when taken in the amounts found in foods. But there isn't enough reliable information to know if eyebright is safe when taken in amounts found in medicines. It might cause confusion, headache, nausea, constipation, cough, trouble breathing, trouble sleeping (insomnia), and other side effects.

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 & Warnings:

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.

Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
