This Natural Aromatherapy Salt Lamp is hand carved from salt excavated from the Himalayan Mountains. When the salt is heated, it releases negative ions, as well known as “Vitamins of the Air”. The negative ions are said to calm nerves, regenerate cells and purify the air for a holistic experience. The salt stone lamp also comes with a steel cup to use with essential oils. When the lamp is heated, the aroma and benefits of the oils are released into the air.
