肺
fèi脏腑
概述
The Lung (Fei) is one of the five zang organs in Traditional Chinese Medicine, associated with the Metal element and considered the 'canopy' of the body. It governs Qi, respiration, and the regulation of water passages, while also controlling the skin and body hair.
理論要點
- The Lung is located in the chest, belongs to Metal in the Five Phases, and is classified as the 'yin within yang'. It is also called the 'Hua Gai' (canopy) and the 'delicate organ' (Jiao Zang), paired with the Large Intestine in the exterior-interior relationship.
- The Lung governs Qi and respiration: it inhales clear Qi and exhales turbid Qi, and it generates 'Zong Qi' (ancestral Qi) that accumulates in the chest to drive the circulation of Qi and blood throughout the body.
- The Lung controls dispersion (Xuan Fa) and descent (Su Jiang) of Qi and body fluids, ensuring that fluids are distributed downward and outward, and that the respiratory and water passages remain open.
- The Lung regulates the water passages (Shui Dao) as the 'upper source of water', and it 'faces the hundred vessels' (Chao Bai Mai), assisting the Heart in propelling blood circulation. Its external manifestation is the skin and body hair, its orifice is the nose, its fluid is nasal discharge, and its emotion is grief or sadness.
- The Lung is the most vulnerable organ to external pathogenic factors, as they often attack it first, leading to patterns such as Wind-Cold invading the Lung, Wind-Heat invading the Lung, Dryness invading the Lung, Phlegm-Damp obstructing the Lung, Lung Qi deficiency, and Lung Yin deficiency.
常見病機
- External pathogens (Wind, Cold, Heat, Dryness) can invade the Lung, impairing its dispersing and descending functions, leading to cough, wheezing, nasal congestion, and sore throat.
- Deficiency of Lung Qi or Lung Yin can cause weak respiration, shortness of breath, low voice, dry cough, and spontaneous sweating, often due to chronic illness or overexertion.
- Phlegm-Damp accumulation in the Lung obstructs Qi flow, resulting in productive cough with copious sputum, chest oppression, and breathlessness.
- Impaired regulation of water passages by the Lung can lead to edema, urinary disorders, or accumulation of fluids, as the Lung fails to disperse and descend fluids properly.
日常調養
- Maintain regular breathing exercises, such as deep abdominal breathing or Qigong, to strengthen Lung Qi and promote proper dispersion and descent.
- Avoid exposure to cold, wind, and dry environments, and protect the neck and chest area, as the Lung is sensitive to external pathogens.
- Cultivate emotional balance, especially managing grief and sadness, as these emotions directly affect the Lung and can weaken its Qi.
