Tea Information

Research Summary

Maple leaf has a tradition as a mild antioxidant and liver-support tea; preclinical work shows polyphenol antioxidant activity, especially in Japanese red maple varieties. Clinical evidence is limited; it is not a treatment for liver disease, diabetes, or any disease, though it remains a gentle, pleasant autumn cup.

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.
