How It Works

While there are many chemicals that may be active in eyebright, none of them has been proven to have any effect on eye inflammation or irritation. Some herbal texts suggest that the astringent actions of eyebright may reduce eye irritation while others suggest that eyebright may also have antibacterial actions topically. To date, there are no clinical studies to support or refute these proposed actions.

How to Use It

Traditional herbal texts recommend a compress made with 1 tablespoon (15 grams) of the dried herb combined with 2 cups (500 ml) of water and boiled for ten minutes.3 The undiluted liquid is used as a compress after cooling. The German Commission E monograph does not support this application, due to possible impurities in non-pharmaceutical preparations.4 Consult with a physician knowledgeable in the use of herbs before applying eyebright to the eyes.

Internally, two to three cups per day of eyebright tea is sometimes recommended. Dried herb, 1/2–3/4 teaspoon (2–4 grams) three times per day, may also be taken. The tincture is typically taken in 1/2–1 1/4 teaspoons (2–6 ml) three times per day.
