Cramp bark (Viburnum opulus)

Parts used: bark

Medicinal uses: Effective at relieving tense muscle, whether in smooth muscle or skeletal muscles. It may be taken internally or applied topically to ease muscle tension. This plant also treats symptoms arising from excess muscle tension, including breathing difficulties in asthma and menstrual pain caused by excessive contraction of the uterus. The herb also relieves constipation, colic, and irritable bowel syndrome, as well as the physical symptoms of nervous tension. In some cases of arthritis where joint weakness and pain have caused muscles to contract significantly, Crampbark can bring about significant relief. Crampbark is also commonly used in treatments for high blood pressure and other circulatory conditions.

Cautions: None known (Chevallier 150).
