PHYTOTHERAPY
Cramp Bark (Viburnum opulus L., bark)
Cramp Bark is the dried inner bark of Viburnum opulus, a deciduous shrub native to Europe and North America. Its bark contains active plant compounds including coumarins (such as scopoletin), flavonoids (including catechin and epicatechin), and proanthocyanidins, alongside other phenolic and bitter constituents(1). These phytochemicals are thought to support the body by helping reduce smooth-muscle spasms while contributing to antioxidant activity and mild regulation of nervous system tension(2).
Traditional use in Western herbal medicine highlights Cramp Bark for menstrual cramps, leg or back spasms, and general muscular tension(2).
