Apples are used in many ways in Chinese Medicine. Apple treats phlem-damp accumulation in lung and spleen. Lung and spleen are two major organs to deal with phelm-damp accumulation in our body. When phlem-damp accumulates, we cough with copious phlegm in severe case, and also experience chest stuffiness with difficult breathing. Two to three apples a day, improves the symptom. Of course consult with your local acupuncturist to help you with more detailed treatment.
