This is for back, joint, foot, and muscle pain in conjunction with massage therapy, an important part of feeling better. The olive oil in the mixture helps enable a longer massage, as the alcohol evaporates more quickly. Combined in a rubbing alcohol and olive oil base are extracts of hops, wormwood, comfrey, arnica, cayenne, mullein, mugwort, and St. John's wort with essential oils of white thyme, camphor, wintergreen, clove, cajeput, spruce & nutmeg. It's a 4 oz. plastic bottle with a flip-top applicator lid.
