In the treatment of lung cancer, regardless of whether it is small cell lung cancer or non-small cell lung cancer, TCM often adopts the method of differentiation of evidence and treatment. If a patient has a cough with yellow or pus sputum, blood in the sputum, thick coating, and a slippery or sunken pulse, the patient is often identified as having phlegm and heat blocking the lung. Common formulae include Qianjin reed stem soup, Er Chen Tang, etc. In addition, Chinese medicine treatment for lung cancer also adopts the method of identifying the disease. Common Chinese medicines such as Xuan Shen, Tian Dong, Snake Tong Cao, Half Branch Lotus, Bai Ying, etc. have certain therapeutic effect on any type of lung cancer.
