Most tumor patients are not unfamiliar with anti-cancer proprietary Chinese medicines (PCMs). Since PCMs have the advantage of being easy to take and suitable for tumor patients who have to undergo long-term treatment, anti-cancer PCMs are widely used in clinical practice. In TCM oncology clinics, doctors often hear patients ask: Can I take a certain anti-cancer proprietary Chinese medicine as the patient has gotten better after taking it? The anti-cancer proprietary Chinese medicine also needs to be taken according to evidence. At present, the phenomenon of abusing anti-cancer pCms without identification does exist. The abuse of anti-cancer pCms is common. Anti-cancer pCms come from the long-term clinical practice of Chinese medicine practitioners in China, and there are many varieties. In the treasure house of traditional medicine in China, there are many records and discourses on tumors, and ancient physicians created many effective prescriptions based on their knowledge of tumors. For example, Zhang Zhongjing developed the famous formula for activating blood circulation and resolving silt, such as Tao Ren Cheng Qi Tang, Rhubarb Sting Worm Pill and Gui Zhi Fu Ling Pill, which are still widely used in the treatment of liver cancer, stomach cancer and cervical cancer. Chen Shigong created Toadstool Pill and Yushu Dan in the Ming Dynasty, and Wang Hongxu created Rhizoma Pill and Xiaojin Dan in the Qing Dynasty, all of which are famous formulas for clinical treatment of tumors in Chinese medicine. The main role of Chinese medicine in treating malignant tumors is twofold: one is as an adjuvant drug, i.e. to improve the efficacy of radiotherapy and chemotherapy. The second is as a therapeutic drug to stabilize the tumor and improve the symptoms. In the comprehensive treatment of tumor, the reasonable application of anti-cancer proprietary Chinese medicine has certain advantages in improving various symptoms of middle and late stage tumor, enhancing the immune function of the body, alleviating the side effects of chemotherapy and radiotherapy, and promoting the physical recovery of patients after palliative surgery treatment and radiotherapy and chemotherapy. However, the phenomenon of abusing anti-cancer Chinese medicine is rather serious at present. If they are not applied in a standardized way, they not only fail to achieve the effective therapeutic effect of drugs, but also aggravate the disease due to the superposition of toxic side effects of drugs. At the same time, it wastes a lot of medical expenses and increases the financial burden of patients. The use of anti-cancer Chinese medicine is the key of Chinese medicine, and so is the use of anti-cancer Chinese medicine. The use of anti-cancer proprietary Chinese medicine should also be selected according to the actual condition of the patient, and should not be abused or used for a long period of time. It is undoubtedly absurd to talk about treatment in isolation from specific patients and specific conditions. The clinical conditions of different patients are different, and even the same patient has different clinical conditions at different stages. According to Chinese medicine, the pathogenesis of malignant tumors always involves “the struggle between good and evil”. In general, anti-cancer Chinese medicines have two effects: “anti-cancer” and “supporting the righteousness”, which one is more important than the other. In the early and middle stages of the disease, tumor patients are “positive and evil”, so it is appropriate to “attack the toxins and eliminate the evil”. For patients who have undergone surgery and radiotherapy, the Chinese herbal medicine should focus on “supporting the righteousness” to alleviate the adverse effects of radiotherapy and chemotherapy, so that patients can better pass these treatment levels; for patients with advanced cancer, most of the tumors have metastasized distantly, the evil toxins are arrogant and the righteousness is weak and weak, at this time, the treatment should not focus on attacking and attacking, but on “supporting the righteousness and consolidating the root”. At this time, treatment should not be focused on attacking, but on “supporting the righteousness and strengthening the root”.
