This latest Dr. Bill formulation is an all-natural muscle balm made with premium therapeutic ingredients like, ginger root, clove oil, and Arnica. A little Hammer Balm goes a very long way, so our one-ounce bottle offers much more relief than you might think at first. You can also try our quarter-ounce sample size, suitable for travel, too. Triple Action Transdermal Muscle Cream. Penetrates deep into sore, tired muscles. Reduces inflammation and alleviate pain. Pleasant scent.
