Modern Evidence

Evidence level: Insufficient

Sorrel has a tradition as a cooling, digestive herb; it is rich in vitamin C and oxalic acid. Clinical evidence is insufficient; it is not a treatment for digestive disorders, scurvy, or any disease, and oxalate content limits use in kidney stones.

Evidence levels describe the state of research for the traditional use discussed here, not a recommendation. Historical use does not imply effectiveness.
