Halotherapy (dry salt therapy) is an all natural holistic treatment that mimics the microclimate of the salt cave.  Salt mine workers in the 1800’s were found to have superior respiratory systems, free from lung diseases that many coal and metal miners suffered from.  The natural sodium chloride that filled the cave was found to reduce inflammation in the miners’ lung and air passageways.  Salt caves were then discovered in Poland, Russia, Romania, Austria and the Ukraine, which is why Eastern Europe is where halotherapy began as a medical treatment.
