Made of high-quality ceramic and contains food-grade Himalayan pink salt. Like gargling & nasal rinses (Meti), inhaling is another way to enjoy the wonders of Himalayan salt in your home or on the go. When you inhale through the mouthpiece, micron-sized particles of Himalayan pink salt enter the respiratory system, including the sinuses, nasal cavities, throat and lungs. Inhaling the micron-size salt particles help cleanse the respiratory system as a whole.
