Relationship between lung and liver

The relationship between lung and liver is mainly manifested in the opposition and restriction of qi movement.

Lung governs qi to ensure the sufficiency and regulation of qi in a body; The liver relaxes and contracts the machine, promoting the smooth flow of qi throughout the body. The lung governs the descending, and its qi is smooth; Liver governs ascending hair, and ascending hair is the best qi. Lung qi is sufficient, and the decline is normal, which restricts and counter-regulates the rise of liver qi; Liver-qi dispersing, ascending, restricting and regulating the descending of lung-qi.

Liver ascending and lung descending are mutually restricted and coordinated, which not only maintains the activity of qi between liver and lung, but also plays an important role in regulating the flow of qi throughout the body. Under pathological conditions, the disorder of ascending and descending of liver qi and lung qi often affects each other and is mutually causal. If liver depression turns into fire, it can burn lung yin, leading to disorder of descending qi, such as blushing, irritability, cough and chest pain, and even hemoptysis, which is called "liver fire invading lung" or "wood fire punishment"; On the other hand, if the lung is damaged by heat, it will also affect the liver and make it lose its function. Such patients often cough at the same time, and have symptoms such as headache, dizziness, bitter mouth and dry throat, blushing eyes, irritability and chest pain.
