EUCALYPTUS STEAM® - Cleansing vapors for the shower™. The cleansing vapors of eucalyptus are well known for deep support of respiratory health. We combine it with concentrated cooling peppermint for an awakening and refreshing shower. How to use in the shower: Place one or two rounds in the shower in the direct stream of water. As the round(s) get wet, they begin to dissolve and release potent essential oils into the hot shower steam. Our patent pending slow release technology gives you several minutes of refreshing, EUCALYPTUS STEAM® filled air. Contains about 9-10 pieces, enough for 9-10 showers. Recyclable glass and metal packaging pure essential oils
