Research Summary

Evidence Level: Insufficient

Cranesbill has a tradition as an astringent digestive, throat, and wound herb; preclinical work shows antioxidant and tannin-rich activity. Clinical evidence is insufficient; it is not a treatment for diarrhea, sore throat, or any disease, though it remains a gentle folk astringent tea.

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.
