Cramp Bark
Viburnum opulus
Cramp bark earned its common name honestly. For generations, herbalists have turned to the stripped bark of this hedgerow shrub to ease menstrual cramps, muscle spasms, and the kind of gripping tension that settles into the body. European folk healers and later the 19th century American Eclectic physicians both reached for it for what was then called female complaints, and it found a steady place in the home apothecary alongside chamomile and raspberry leaf. It was also brewed for the tightness that comes with a tense chest or an overworked back.

Traditional preparations.
The classic preparation for easing menstrual or muscular cramping, taken warm at the first sign of tension.
Traditionally, 1 to 2 teaspoons of dried cramp bark are simmered gently in 250 ml of water for 10 to 15 minutes, then strained and sipped warm.
A gentler, more calming version of the decoction for evening use.
Combine a small cup of the strained cramp bark decoction with a standard chamomile infusion, made by steeping 1 teaspoon of dried chamomile flowers in freshly boiled water for 5 to 10 minutes.
Safety.
The raw berries are bitter and can cause nausea or stomach upset if eaten, so they're not eaten fresh off the shrub. Because cramp bark acts on smooth muscle, including the uterus, it has traditionally been avoided during pregnancy, and it may add to the effects of sedatives or blood pressure medication.
