Crampbark (Viburnum opulus) is a deciduous shrub in the Adoxaceae family that is native to Europe, North Asia, and parts of North America. It is traditionally valued for bark and is known for a deciduous shrub traditionally valued for its bark in Western herbal practice.
Traditionally, the bark has been used in decoctions, tinctures, and older Western herbal formulas associated with spasms, tension, and women’s herbal support. The bark rather than the berries is the main part used in herbal practice.
Crampbark is also an ornamental shrub with showy white flower clusters and bright red berries. It may be found in hedgerows, woodland edges, and cultivated landscapes.
