Himalayan Salt Lamps serve as quality products that are not only attractive as decor but also sought after due to their therapeutic/health benefits. Their negative ions provide a refreshing air quality while the lamp displays a soothing light. Studies link the use of Himalayan Salt therapy to a brightening of moods & decrement of depressive symptoms. The use of essential oils paired with our lamp diffusers will offer the special benefits of aromatherapy spanning from harmonizers & purifiers to antiseptic & antidepressive effects. Our lamp diffuser comes with a metal container where you could pour the essential oils of your desire. Since our products are composed of natural rock, color shades may vary.
