Salt Therapy, or Speleotherapy, is a widely used natural remedy that goes back several centuries . The healing atmosphere of salt caves were acknowledged as far back as medieval times, with monks taking the sick down into salt caves to allow them to breathe air saturated with salt particles. These salt particles were freshly created and activated by monks crushing stalactites. The use of salt as a health remedy has been around since the Greeks, when Hippocrates recommended salt inhalation as a respiratory treatment.
In the 20th century, Eastern European physicians and engineers learned to simulate the conditions inside salt caves. In modern halotherapy ("halo" is Greek for salt) a generator to blows tiny microparticles of salt into a room. Salt therapy is studied, recognized and used in many European hospitals to treat various respiratory ailments. Although it has yet to be clinically researched in a controlled and extensive way in the United States, many wellness centers are now incorporating Salt Therapy into their practices.
