There is no herbal or other cure for emphysema, period. It's a life time disease mostly caused by smoking, and it involves damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise. The most common cause is cigarette smoking. It is a subset of COPD. https://lunginstitute.com/blog/emphysema-prognosis-treatment-options/—
