Background

Cramp bark (Viburnum opulus) is native to Europe, northern Africa, and northern Asia. It has been used throughout the world as an ornamental plant. The bark has traditionally been used for cramps, including menstrual cramps and cramping associated with arthritis. Interestingly, a laboratory study found that viopudial isolated from Viburnum opulus had antispasmodic effects on smooth muscle. However, there is currently insufficient available evidence in humans to support the use of cramp bark for any indication.
