Origin and history
Viburnum, also known as snowball bush for the beauty of its flowers, is a plant native to the temperate regions of Europe and Asia. Used for centuries in traditional medicine, it was renowned for its soothing effects on female and muscular pain. Native Americans used it under the name cramp bark to relieve spasms and tension. In modern herbal medicine, viburnum is recognized as a relaxing, antispasmodic plant that regulates the female cycle.
