Overview
Sheep Sorrel is a small perennial herb with arrow-shaped leaves and a distinctly sour, lemony taste due to its oxalic acid content. Historically used in traditional medicine systems worldwide, it gained modern attention as a key ingredient in the Essiac tea formula. The plant has been valued for its nutritional content and traditional use in supporting immune and digestive health.
Traditional Use
Sheep Sorrel has been used traditionally as a spring tonic, for digestive support, and as a mild diuretic. Native American and European herbalists used it for fevers, inflammation, and skin conditions. It became widely known as one of the four herbs in Essiac tea, a formula traditionally used for immune support and promoted for cancer support, though scientific evidence for cancer treatment is lacking.
