Effol Mouth Butter helps the bit to slide more easily into a comfortable position in your horse's mouth, making your horse more content and increasing the quality of your ride. Horses love the fresh taste of apple which can also stimulate chewing for a soft mouth and more sensitive contact. Effol Mouth Butter also protects sensitive mouths like a second skin with zinc oxide and balsam of Peru while allantoin keeps the corners of the mouth soft and supple. Simply rub it onto the corners of the horse's mouth before and after riding. It can also be applied to the bit to encourage acceptance.
