The liver and lung

This relationship is mainly manifested in the ascending and descending movement of qi. The lung qi normally descends and the liver qi normally ascends, in order to maintain the harmonious function of the vital activities of the body. If the liver qi is depressed, it may transform into fire which goes upward along the meridian to consume the fluid of the lung, giving rise to such manifestations as hypochondriac pain, irritability, cough and haemoptysis, known as " invasion of the lung by liver fire. " Conversely, dysfunction of the lung in descending may lead to pathogenic dryness and heat, which descend to consume the yin of the kidney and liver, stirring up hyperactivity of liver yang. In this case, in addition to cough, there may be referred pain in the chest and hypochondriac region, dizziness, headache and redness of the face and eyes
