if you mean a practical cure for COPD, no there's not. The closest we get to practical are things you can do for yourself: quit smoking, develop a daily exercise program (30 minutes non-stop aerobic activity and strengthening exercises), get as close to your normal weight as possible, eat healthy, take your meds, get to your doc ASAP if you get something respiratory. Do all those things and you'll make more improvement than you will with any pills and potions. You do have to do all of them, including taking your meds.
