Sore No-More Performance Ultra Poultice was developed by veterinarians with top competitors in mind. It combines high-grade bentonite clay with a potent dose of our natural, clinically-proven formula of arnica, rosemary, witch hazel, ginger and anti-inflammatory comfrey. Formulated at clinical strength without any ingredients on the FEI's drug regulations list. The silky smooth texture comes from the same healing bentonite clay used in face masks for people. The naturally soothing ingredients effectively draw out heat, fluid and toxins while promoting circulation and cooling the area. It’s as gentle on your own hands as it is on your horse’s skin.
