There is no definite answer to the question of how many millimeters of lung nodules can be eliminated by taking traditional Chinese medicine, and it should be determined by combining the patient’s condition and the cause of the disease. Chinese medicine believes that lung nodules are caused by phlegm and qi stagnation or qi stagnation and blood stasis, and should be treated with medicines that activate blood circulation and remove blood stasis, soften and dissipate hard nodules, and resolve phlegm and pass through the collaterals, taking into account the patient’s specific symptoms and condition, etc. However, there is no clear answer to the question of how many millimeters of lung nodules can be eliminated, which is mainly affected by the individual’s condition. For example, for lung nodules caused by blood stasis, medicines such as Hematopoietic Granules can be taken to dissipate blood stasis and eliminate nodules, and to activate qi and blood circulation; if the lung nodules are caused by qi stagnation in the local area, medicines such as Chaihu Liver Shuji Pill and Xiaku Cao Granules can be chosen to ease the liver and dissipate the nodules. Lung nodule treatment needs to clarify the cause of the disease in a timely manner, under the guidance of the doctor to identify the cause of the disease, do not take drugs on their own.
