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