What is Salt Therapy? Dry Salt Therapy, also known as Halotherapy, is an ancient practice that harnesses the anti-fungal, anti-bacterial, anti-microbial and anti-inflammatory properties of salt to promote health and healing, specifically for the respiratory, immune, and skin systems. The therapeutic inhalation of salt is made possible through the use of a halo-generator that disperses micro-sized salt particles into the air.
