The name Salt Therapy could be used for anything related to salt as health support, like gargling with salt water, drinking sole, salt bath... Halotherapy or Dry Salt Therapy is a more accurate name for a therapy that means breathing a negative ion rich dry salt micro-climate, just like in natural salt mines. It is a natural, safe, non-invasive, alternative therapy which is also very relaxing and induces stress relief. It requires special equipment, called a dry salt Halogenerator. Only Salt Spas equipped with such device offer the most therapeutic form of Salt Therapy.
