Cramp Bark: What It Is and How to Use It
Cramp bark is the dried bark of the European cranberry bush (Viburnum opulus), a shrub native to Europe and parts of Asia.

Frequently Asked Questions
Why is it called cramp bark?
The name comes from its traditional reputation: herbalists historically turned to cramp bark for soothing muscle cramps and tension. It has been a staple of Western herbal traditions for centuries, valued as a calming herb for the muscles.
How is cramp bark traditionally used?
Cramp bark is traditionally used as a decoction — the bark is simmered in water to draw out its properties — or as a tincture. Herbal references describe it as traditionally used for muscle cramps, including menstrual cramps, and for general muscular tension.
What does cramp bark taste like?
Like most barks, it brews into a strong, earthy, slightly bitter tea. It is not typically drunk for flavor alone — most people prepare it as a functional herbal decoction, sometimes blended with more pleasant-tasting herbs like ginger or cinnamon.
Is cramp bark the same as black haw?
They are close relatives but not the same plant. Cramp bark comes from Viburnum opulus, while black haw comes from Viburnum prunifolium. Both have similar traditional uses in herbal practice, and some herbalists use them interchangeably, but they are distinct species.
Did you know? Cramp bark was listed in the United States Pharmacopeia — the official compendium of medicines — from the late 1800s through the mid-1900s, reflecting its established place in American herbal medicine (source: historical USP records).
