ABSTRACT
Theory of"yang leading to qi and yin leading to formation",as the law of nature giving birth to life,has wide applicability and can be used to interpret the nature and pathogenesis characteristics of pulmonary sarcoidosis.Based on yin-yang theory,this article elaborated on the pathological essence of pulmonary sarcoidosis.Under the guidance of the theory of"yang leading to qi and yin leading to formation",the treatment strategy of discerning the degree of yang qi deficiency and stagnation when forming pulmonary sarcoidosis,replenishing and unblocking the body's yang qi,and simultaneously soothing the liver and lungs,clearing collaterals,detoxifying,and dispersing masses to dissipate yin and coagulation,has certain guiding significance for clinical diagnosis and treatment of pulmonary sarcoidosis.
