We are educating ourselves by reading studies and experimental efforts to reduce the effects of COPD. If there are no studies, literature how would one become educated on the subject. There are all sorts of scams out there, and predators waiting to take your money with false claims of cures without the documentation to support their claims. If you are willing to spend the money chasing it, then go for it! I will stick to the scientific studies and statistical data that indicates a reason/reasons for treatment options. There are also clinical trials that one may become a participant!
