Lou Bai-Ceng treats asthma

The primary factor in asthma is phlegm, and this is phlegm  lurking internally in the Lungs. It is brought out by a variety of external factors, whether externally contracted wind-cold, or foods, or emotional situations, or overwork, but it is particularly sensitive to weather change. This illness recurs and repeats on and off for a prolonged period of time, after which not only are the Lungs injured, but the Kidneys and Heart as well.
