There’s a new Asthma treatment gaining momentum in several countries, especially in Israel (home of the famous Dead Sea):
Salt room therapy started in Eastern Europe, in mines. Miners with lung conditions noticed that they felt much better and even were “cured” of their diseases while in the mines. Today, a patient sits in a room built of salt blocks mined from far below the ground in Ukrainian caves. The air in the salt room contains high quantities of negative ions, which seem to clear mucus and purify the lungs. The salt also helps asthmatics cough up their mucus.
