Patients with malignant tumors are often weak and have low immune function, especially after surgery, radiation therapy and chemotherapy are very prone to anemia, leukopenia, lack of appetite, nausea, vomiting and other toxic side effects. In Chinese medicine, the symptoms are mostly identified as spleen and kidney yin deficiency, qi and blood deficiency, qi and yin deficiency, liver and kidney yin deficiency, and liver and stomach disharmony. Chinese medicine can improve the quality of life by strengthening the body, improving anemia and promoting the rise of white blood cells. Blood stasis is one of the main causes of tumor. Many medical doctors have discussed the connection between blood stasis and tumor diseases such as “stone obstruction”, “addiction” and “choking”. Nowadays, it is believed that cancer cells or microscopic cancer emboli are often present in the blood of malignant tumor patients, and when blood flow slows down and stagnation of blood stasis occurs, it often causes the planting or spreading of cancer cells. The method of clearing heat and detoxifying Chinese medicine believes that Chinese herbs have the effect of clearing heat and detoxifying, dispelling evil and supporting righteousness. Clinically, February rhizome (white flowered snake’s tongue), half-branch lotus, summer cress, yellow groundnut and horsetail are commonly used to promote the dissipation of accumulated cancer cells or to promote the transformation of abnormal cells into normal cells. In addition to anti-cancer effects, many herbs with heat-clearing and detoxifying properties are also believed by Chinese medicine to enhance the immunity of the body and reduce the toxic side effects caused by chemotherapy and radiation treatment. Phlegm is a tangible pathological product produced by the loss of harmony between qi and blood in the internal organs of the body and the abnormal transportation of fluid. Phlegm can play a facilitating role in the process of cancer formation, especially when phlegm and blood stasis are combined to form phlegm. Tumors are treated with phlegm, which is also a feature of Chinese medicine. According to Chinese medicine, cancer toxicity is cold in nature. Once the cancer develops, the blood channels will be injured first, so that pathological changes such as blood stasis, dampness, phlegm condensation, qi stagnation and toxicity will occur one after another. It forms evil qi locally in the cancerous lesion. In clinical practice, the toxicity of worm medicine is often used to loosen the root of the disease, attack the hardness and break the accumulation, that is, “attacking poison with poison”. Chinese medicine has various methods to treat tumors, and the prescriptions of each practitioner are different. The theory of Chinese medicine is profound and profound, and many single and experimental prescriptions summarized clinically play a role in the comprehensive treatment of tumors.
