Our sauna aromatherapy essences are packaged in 100 ml amber glass bottles to maintain the product’s integrity. Plastic bottles can react with the essence ingredients therefore we won’t use them. Our black phenolic caps have a special funnel shaped insert to prevent leakage and air infiltration. These should NEVER be added directly onto the sauna rocks or any heater. Rather a cap full or two should be added into a full sauna bucket of water. Then with a sauna ladle sprinkle the mixture onto the hot rocks. The resulting fragrance will quickly spread throughout the room. Sauna essences are refreshing and invigorating, and by varying the scent from time to time you can enhance your sauna experience. Available in Eucalyptus, Citrus Orange, Rain, Wintergreen, and Vanilla.
