Emphysema/COPD cure at 74?

My Mother at 74 has been diagnosed with COPD. She smoked for 50 years and quit two months ago. She had an improvement with breathing for three weeks after quitting, then the lungs became much worse than when she was smoking! Now she cannot even walk 30 feet without having to hold on or sit to catch her breathe. I've been researching Dr. Schulze 's incurables program. It includes a Hyperthermia routine which seems quite dangerous for a 74 year old and am afraid to take this on myself. She cannot see very well so I would need to walk her through each step. I cannot find a holistic/herbal/naturalist doctor in my area as I've been looking into that also.

Thank you for any information or advise.
