A poultice wrap involves applying a clay-based product onto a horse’s leg, wetting it and then covering it with brown paper and a standing wrap. It cools the leg as it dries, tightening tendons and ligaments. In this video, Laurie Pitts demonstrates how to put on a poultice wrap. SAFETY NOTE: As Laurie explains, crouching when working around a horse’s legs is the safest posture so that if the horse startled, you would be able to move away quickly.
