Sounds promising. My mother has COPD & emphysema, 24/7 oxygen since 2/2007, I wish it was definite and available to help her. Her lung function is way below 30% and I fear the near future for her.
Has she tried caffeine? A medical doctor said Caffeine contains a molecule similar to that found in lung-inflater medications used to treat asthma. People say their breathing improved by drinking coffee. Some threw away inhalers. NOTE: Use brewed, caffeinated type.
