The principle of Chinese medicine in treating diseases can be explained by treatments. The treatments used in Chinese medicine to treat malignant tumors include activating blood circulation and removing blood stasis (promoting blood circulation and eliminating blood stasis in the body), invigorating the spleen and removing phlegm, and benefiting qi and nourishing yin (tonifying qi and nourishing yin and fluids), and so on. 1. Activating blood circulation and removing blood stasis: malignant tumor belongs to the category of cancer in Chinese medicine. Cancer may appear as localized lumps, and if accompanied by dark tongue and petechiae, it may be caused by localized stasis and blood stagnation, so the method of activating blood circulation and removing blood stasis can be chosen, and the commonly used prescriptions include Hematopoietic Blood Stasis Elimination Soup, Diaphragmatic Blood Stasis Elimination Soup, and so on. 2. Strengthening the spleen and resolving phlegm: if there are localized lumps, accompanied by sputum and saliva, tastelessness, abdominal distension and diarrhea, etc., it may be caused by phlegm gathering locally, accompanied by spleen deficiency, and commonly used prescriptions include Xiangsha Liujunzi Soup and so on. 3. Benefiting qi and nourishing yin: some advanced cancer patients may suffer from deficiency of qi and yin (deficiency of both qi and yin), which may be manifested by fatigue, shortness of breath, dry mouth and thirst, emaciation, spontaneous sweating (involuntary sweating during the daytime, aggravated by sweating with slight movement), night sweating (abnormal sweating after falling asleep, stopping sweating after waking up), etc. Commonly used prescriptions include Shengmu San. No matter activating blood circulation and removing blood stasis, strengthening the spleen and removing phlegm, or benefiting qi and nourishing yin, the basic method of treatment is to support positive qi and get rid of evil qi. Note that Chinese medicines do not have the effect of directly killing cancer cells. If you want to use Chinese medicines to treat cancer, it is recommended that you go through a doctor’s diagnosis and then treat with evidence-based therapy.
