Cramp Bark (Viburnum opulus) has a long history of use in traditional herbal medicine, particularly in North America and Europe, for supporting muscle health. Traditionally, it has been employed primarily for its antispasmodic properties, meaning it is thought to help relieve muscle cramps, tension, and spasms. Native American and European herbalists used preparations of Cramp Bark to ease muscle cramps—including those associated with menstruation, leg cramps, and other forms of muscular discomfort.

The name "Cramp Bark" itself reflects its historical use for muscle cramps. The bark contains various compounds, such as viburnine, coumarins, and flavonoids, which are believed to have a relaxing effect on smooth muscle tissue. However, despite its widespread traditional use, there is a lack of robust clinical trials or high-quality scientific evidence directly supporting its effectiveness for muscle health in humans. Most of the available data come from anecdotal reports, traditional texts, and animal studies that suggest a possible antispasmodic action.

In summary, while Cramp Bark is traditionally used to support the muscles body system, especially for relieving cramps and spasms, strong scientific validation for these effects is currently lacking. Its use for muscle support remains rooted in historical practice rather than modern clinical research.
