Potentilla anserina (commonly known as Anserina or Silverweed) has a longstanding history of use in traditional European herbal medicine, primarily for its antispasmodic properties. Traditionally, it has been used to relieve muscle cramps, spasms, and general muscle discomfort, particularly those associated with menstruation or digestive disturbances. Folk medicine often employed Anserina as a tea or extract to soothe smooth muscle spasms in the gastrointestinal tract and uterus.

The rationale for its use in the muscular system is mainly based on these antispasmodic effects observed in traditional practice. Some early pharmacological studies have corroborated that extracts of Anserina can relax smooth muscle tissue in vitro, possibly due to constituents such as flavonoids and tannins. However, robust clinical evidence from human trials is lacking, and most modern scientific literature focuses on its use for digestive and menstrual complaints rather than for support or strengthening of skeletal muscles.

In summary, while Anserina is traditionally used to support the muscular system by alleviating muscle spasms, particularly smooth muscles, scientific validation for its effectiveness—especially for skeletal muscle health or athletic performance—is limited. Its use for muscle support is thus justified primarily by traditional rather than strong scientific evidence.
