Tea Information

Research Summary

Bupleurum has a long TCM tradition as a harmonizing liver herb. Clinical evidence is limited; preclinical work shows hepatoprotective and anti-inflammatory activity, but it is not a treatment for liver disease, hepatitis, or any condition, and interacts with immune-suppressive therapy.

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.
