Why You Need It
- Soothes Eye Strain: Helps reduce inflammation and irritation caused by screen time or reading.
- Relieves Allergy Symptoms: Acts as a natural astringent to dry up a runny nose and watery eyes.
- Fights Bacterial Growth: Contains potent antimicrobial properties to support eye health.
- Reduces Puffiness: Topical applications can help shrink swollen tissues around the eyes.
Deep Dive
Eyebright works primarily through tannins, which have an astringent effect. This means they tighten tissues and reduce secretions—perfect for those watery, itchy eyes that come with hay fever or digital eye strain. It also contains aucubin, a compound known to protect the eye from damage caused by sunlight and oxidative stress. While it won't cure cataracts or replace glasses, it acts as a powerful supportive tonic to keep your eyes comfortable and functioning smoothly.
Natural Food Sources
Unlike Vitamin C or Iron, Eyebright is a specific herb, not a nutrient found in common fruits and veggies. It is generally foraged or cultivated for medicinal use.

Supplementation
Dosage: There is no official RDA. Standard herbal doses are roughly 300–600 mg of dried herb in capsules, 2–3 times daily.
Usage: It is best used short-term for acute issues (like allergy season or eye fatigue), not necessarily as a daily lifelong supplement. For direct eye relief, a sterile Eyebright eyewash is the preferred method over oral supplements.
