Try NAC. My husband has COPD and I give one 600mg capsule in the morning, and one in the evening. He seems to be much better than before. He barely uses his rescue inhaler anymore. NAC is very good for clearing out excess mucus opening up the airways. Before after five yrs of not smoking he was still coughing up brown mucus. Now he coughs up none. He's been on it now for about 1 1/2 yrs. Good luck to you and your wife.
