For deep support of respitory health and for a rejuvinating shower experience, place one or two rounds in the shower, in direct stream of water. As the rounds get wet, they begin to dissolve and release potent essential oils of eucalyptus and peppermint into the hot shower steam. The patent-pending slow-release technology gives you several minutes of oil infused steam.
