The healing properties of salt have been recognized for centuries. The increasing popularity of Himalayan Crystal Salt is owed to its natural ionizing properties - its healthy ions counterbalance unhealthy ions in the atmosphere, thereby cleansing the air of impurities. As your lamp grows warm, they emit steady streams of healthy ions to make you feel calmer, more alert, and brighten your mood. Himalayan crystal salt is the highest grade of natural salt available and is toxin and pollutant-free. It is also mineral-rich, containing 84 minerals and trace elements that are essential for the human body.
