Cramp Bark (Viburnum opulus)
Cramp bark is a traditional botanical remedy best known for its ability to relax smooth muscle tissue. It has been used historically in Western herbalism to ease spasms, tension, and pain—particularly in the uterus, digestive tract, and skeletal muscles. Its action is calming without being sedating, making it suitable for both acute and preventative use.
Traditional & Functional Benefits
1. Muscle Relaxation & Spasm Relief
Cramp bark is valued as a powerful antispasmodic, helping reduce involuntary muscle contractions throughout the body.
Commonly used for:
Menstrual cramping
Muscle spasms and tension
Leg cramps
Back spasms
2. Menstrual & Reproductive Support
Often referred to historically as a “uterine antispasmodic,” cramp bark supports the reproductive system by relaxing uterine muscle tissue.
Traditionally used for:
Painful menstruation (dysmenorrhea)
Uterine tension and spasms
Menstrual discomfort associated with stress or tightness
Cramp bark does not stimulate menstruation; instead, it works by calming excessive contractions.

May help with:
Stress-related muscle tightness
Physical tension associated with anxiety
