One 83-year-old wheelchair-bound woman with asthma and emphysema spent at least 2 hours a day on a nebulising machine. She also had a severe cough for years. Four days after starting to take Oralmat, her cough disappeared and she was able to reduce her medication. Three days later, her chest had cleared so dramatically that she was able to walk several blocks unaided.
