Arnica Ice Cooling Gel is a gel-based painkiller used to relieve muscular and joint aches and pains caused by sprains, strains, and arthritis. It's also great for cooling down strained tendons and muscles in horses (it is especially effective as a pre- and post-workout rub). It is also safe and beneficial for use on dogs, and pet parents have reported that the product's relaxing effects have helped them relax. This powerful formula contains the blend of four active ingredients; arnica oil, witch hazel, menthol and camphor. It's a simple to use gel that's safe for both horses and dogs.
