2. Etiology: Qi deficiency is mostly caused by lack of nourishment, or congenital insufficiency, or overwork, old age, infirmity and prolonged illness, which leads to lack of middle qi (weak spleen and stomach qi), and makes the qi’s functions of promoting, defending, consolidating, and gasification out of order.
Lung deficiency is mostly caused by long-term lung diseases, depletion of lung qi, or deficiency of the spleen resulting in insufficient lung qi biochemistry.
