Erodium cicutarium, commonly known as redstem filaree or stork's bill, has a history of use in traditional herbal medicine, particularly among Native American groups and some European herbalists. Its applications have included the treatment of minor wounds, irritation, and as a poultice for skin complaints, which sometimes extended to soothing itching (pruritus). The rationale for its traditional use often centered on its astringent properties, believed to help reduce inflammation and irritation on the skin. However, documentation specifically citing its use for itching is sparse, and references are mostly found in ethnobotanical surveys and anecdotal accounts rather than detailed herbal pharmacopoeias.

From a scientific perspective, there is minimal direct evidence to support the efficacy of Erodium cicutarium for itching. Few studies have examined its phytochemical profile, which includes tannins and flavonoids—compounds sometimes associated with anti-inflammatory or astringent effects. Nonetheless, there are no clinical trials or robust preclinical studies directly addressing its impact on pruritus or skin irritation in humans. As such, any use of this plant for itching is primarily justified by tradition rather than scientific validation, and the overall quality of evidence is low.
