Professor Wang Qi’s clinical experience in treating extra-pulmonary diseases through medicines for regulating the lung meridian is introduced. As the lungs regulate the water passages， govern the skin， store the corporeal soul， and have an exterior-interior relationship with the large intestine， extra-pulmonary diseases such as skin diseases， hydrological diseases， emotional diseases and colorectal related diseases are closely related to the lungs. The treatment is therefore based on the physiological characteristics of the lungs. The treatment methods of clearing lung heat， ventilating lung qi， and moistening the lungs to calm the corporeal soul are introduced， which possess considerable clinical value and are worthy of promotion.
