Although there is no relevant record of pulmonary nodules in ancient Chinese medicine books, the clinical incidence rate remains high, causing patients to panic and worry about the malignant transformation of nodules. Professor Shen Hongmei, based on years of experience in diagnosing and treating pulmonary nodules and clinical practice, believes that the core pathogenesis of pulmonary nodules is the accumulation of phlegm heat in the lungs and the obstruction of blood stasis and turbidity. Using the combination of Erchen Tang and Qianjin Weijing Decoction as the main formula, through the synergistic effect of the two, can not only promote lung Qi, remove blood stasis and disperse nodules, but also improve the spleen and stomach function of patients, enhance positive Qi, and achieve the effect of treating both symptoms and root cause. The combination of the two methods has a definite clinical therapeutic effect, taking into account both the lungs and spleen. While clearing heat, resolving phlegm, and removing dampness, it does not forget to promote blood circulation, remove blood stasis, and disperse nodules. The ancient and modern methods are used to highlight wisdom.
