Overview
Carolina geranium is a small, delicate native North American wildflower that grows 6-18 inches tall. The plant has deeply lobed, palmate leaves that are often tinged with red, especially in cooler weather. Small pink to white flowers with five petals bloom from spring through fall. The distinctive seed pods resemble a crane's bill, giving rise to the common name 'cranesbill.' This hardy annual or biennial grows in disturbed areas, fields, and roadsides throughout much of North America. While less well-known than some other medicinal plants, it has a history of use in Native American and folk medicine.
Traditional Use
Various Native American tribes used Carolina geranium and related wild geranium species for medicinal purposes. The Cherokee used the root as an astringent for diarrhea and dysentery. The Iroquois made a decoction of the plant for mouth sores and sore throats. Other tribes used it topically for wounds, hemorrhoids, and skin conditions. Early American settlers adopted these uses, employing wild geranium as a household remedy for digestive complaints and as a gargle for oral health. The plant's strong astringent properties made it valuable for stopping bleeding and tightening tissues.
