Can this halt progression
Yes, acupuncture coupled with Chinese Medicine (i.e. herbal formulas) properly prescribed is well understood to slow/halt the progression of emphysema/copd. Treatment has to be tailored directly to the individual to be effective so you would ideally work directly with a practitioner over the course of 2-6 months or so depending on a host of factors.
Our emphysema/COPD sections has potential treatment approaches from a variety of angles.
Certainly an anti-inflammatory diet, stopping smoking, and even exercises such as tai chi will be helpful.
