Cramp Bark C/S
Botanical Name: Viburnum opulus
Cramp bark is a plant that grows in North America. As the name suggests, cramp bark is used for relieving cramps, including muscle spasms, menstrual cramps, and cramps during pregnancy. Cramp bark is also used as a kidney stimulant for urinary conditions that involve pain or spasms.
Some people use cramp bark for cancer, hysteria, infection, nervous disorders, a vitamin-deficiency condition called scurvy, and pain and swelling (inflammation) of the uterus (uteritis). Cramp bark is also used to increase urine flow and to cause vomiting, emptying of the bowels, and sleepiness.
Chemicals in cramp bark seem to decrease muscle spasms. These chemicals might also lower blood pressure and decrease heart rate.
