Cramp bark is a large deciduous shrub growing as much as 15 feet (5 m) tall and 15 feet wide. It is native to the moist lowland forests of England and Scotland and naturalized to moist forests of the northern United States and southern Canada. The bark is stripped before the leaves change color in the fall, or before the buds open in the spring. A member of the honeysuckle family, cramp bark bears large white flowers, up to 5 inches (12 cm) across that yield red berries in the fall. The berries are eaten like cranberries, although moderation is recommended. Historically, the berries, once dried, have been used for making ink.


Coumarins, scopoletin, tannin.

Typical Preparations
