Used it on everything - bruises, muscle aches, headaches, as a lip balm, even! Arnica is purported to have properties that help stimulate circulation and help with inflammation. All I know is I love it! Made with locally sourced beeswax, organic cocoa butter, organic arnica-infused avocado oil, menthol crystals and lavender essential oil. Throw one in your gym bag, in your purse or your pocket. Even if you use it as a moisturizing barrier for gardening, it's a great little rub!
