Eyebright, also known as Euphrasia officinalis, is a small herb native to Europe and Western Asia. This herb has been traditionally used for centuries as a natural remedy for eye health and respiratory issues. Eyebright contains beneficial compounds such as flavonoids and tannins that help reduce inflammation and soothe irritated eyes. It has also been used to alleviate symptoms of allergies, hay fever, and sinus congestion. However, caution should be taken when using eyebright, as it may cause adverse reactions in some individuals and should not be used as a replacement for professional medical advice. Always consult with a healthcare provider before using any herbal supplements, especially if you are pregnant, breastfeeding, or taking medication.
