Abstract: Based on The Yellow Emperor's Inner Classic and Treatise on Cold Damage, combined with the academic ideas and clinical experience of traditional Chinese medicine, this study distinguishes and analyzes Shaoyang disease in the Yunqi qi transformation theory. The Yellow Emperor's Inner Classic is one of the main academic sources of Treatise on Cold Damage. Therefore, there are similarities between the Shaoyang Xianghuo disease in The Yellow Emperor's Inner Classic and the Shaoyang Xianghuo disease in Treatise on Cold Damage. However, the scope of the Shaoyang Xianghuo disease in The Yellow Emperor's Inner Classic is broader, and the Shaoyang disease in Treatise on Cold Damage is more refined and auspicious, but it still falls within the category of Shaoyang Xianghuo disease in The Yellow Emperor's Inner Classic. Abnormal qi transformation of the Shaoyang Xianghuo of the heaven and earth can affect the movement of Shaoyang meridian qi in the human body and the movement of the organs connected to it, thus causing Shaoyang disease. The characteristics of the disease vary depending on the combination of the Shaoyang Xianghuo and other Yunqi factors. Abnormality in the body's Shaoyang Xianghuo qi transformation often causes abnormal transformation of Taiyin, Yangming, Shaoyin, and other factors. Shaoyang disease is mostly characterized by fire heat, dampness heat, and excess syndrome, as well as concurrent cold transformation, mixed cold and heat, and deficiency syndrome. The disease is mostly located in the Shaoyang meridian and its affiliated organs. Shaoyang disease often occurs in combination with the meridian syndrome and the visceral syndrome, and is prone to qi stagnation and fire transformation. It fights with the Yangming dry gold, Taiyin damp soil, and Shaoyin monarch fire, resulting in the production of phlegm, fluid, and water, as well as Shaoyang cold transformation syndrome and mixed cold and heat syndrome.
