Cramp Bark - Feed Ingredient
Cramp bark is derived from the bark of Viburnum opulus, a deciduous shrub native to Europe and North America. It contains a variety of phytochemicals, including coumarins, tannins, and valerenic acid derivatives, traditionally used for their antispasmodic and muscle-soothing properties.
In equine supplements, cramp bark is occasionally included in dried or extract form as part of botanical blends designed to support muscle comfort or relaxation. Its inclusion is based on traditional herbal applications and is typically found in formulations aimed at easing muscle tension or supporting mares during their reproductive cycle.
