This small tree is found in Europe as well as North America and parts of Asia.  The bark contains valerianic acid, viburnin, resins, and tannins.  Cramp Bark finds its way in a few formulations (or tinctured individually) for the conditions of pain and muscle cramping.

Why it is Recommended

Listed in the Merck Index as an antispasmodic (uterine), this was a favorite of many of the eclectic physicians for cramps, uterine cramping and pain, pain in the back or thighs, neuralgia, and trigger point pains.  It was also considered anti-abortive in The King's American Dispensary.
