Tea Information

Research Summary

Astringent tannins and iridoids may account for traditional use; controlled trials for eye conditions are lacking. Eye preparations carry contamination risks if not properly formulated.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
