Cramp bark (Viburnum opulus) is a flowering shrub. Many parts of the plant have been used as medicine.

Cramp bark is native to Europe and parts of Africa and Asia and is also grown in many other parts of the world. The bark of the plant has traditionally been used to relieve cramps. Native Americans also smoked cramp bark as a substitute for tobacco.

Cramp bark is used for cramps, cancer, a disease caused by vitamin C deficiency (scurvy), pain and swelling (inflammation) of the uterus, and other conditions, but there is no good scientific evidence to support these uses.
