Jenny Hazan of the Isreal21c Innovation News Service has written an article describing how salt therapy/halotherapy is successfully being used to treat children and adults suffering from a ranging of problems from allergy, to chronic ear or sinus infections, to asthma, bronchitis and even lung disease.
She tells the story of Jonathan Kestenbaum, a Jerusalem residents whose son suffered from chronic ear infections. After only one session he showed signs of improvement; after a full 14-session course he was cured of his chronic ear infactions and two years later he has had only three short-term infections (which all went away on their own without medication). Kestenbaum was so pleased with the success of the treatment that he went on to found a chain of Israeli salt rooms.
