Malignant tumor is a serious disease that threatens people’s health and endangers their lives. In some developed countries, tumor has ranked first in the cause of death. It is reported that 6 million people around the world have tumors and more than 5 million people die from tumors every year. In China, about 1.2 million people have tumors and about 900,000 people die every year. I. Treatment methods of malignant tumors Surgery, chemotherapy, immunotherapy, Chinese medicine, radiotherapy, thermotherapy, isotope therapy, psychosocial support therapy II. The “polycentric theory” of tumor, the recurrence and metastasis of tumor all indicate that local treatment is difficult to cure the tumor, if Chinese medicine is used at the same time, there will be less toxic side effects, good improvement of systemic symptoms, fast recovery of physical strength, high survival rate with tumor and good quality of survival. Scope of application: Patients of all stages of tumor, who have serious complications or poor physical condition, poor immune function, or are not suitable for surgery, radiotherapy or chemotherapy, can use Chinese medicine treatment. The six diseases (wind, cold, heat, humidity, dryness and fire) are caused by wind, cold, heat, dampness, dampness, dampness, dampness, heat, fire, and fire. 2, improper diet, including poor diet, unclean diet, and biased diet. 3, overwork and disorder. Overwork causes imbalance of qi and blood, imbalance of yin and yang, and finally qi stagnation, blood stasis, and phlegm, forming tumor. Overwork leads to obesity and weakness, fat accumulation, decreased resistance, poor qi and blood circulation, stagnation of qi and blood stasis, and tumor development. 4, phlegm does not transform phlegm drink stagnation phlegm blocking meridians 5, seven emotions internal injury joy, anger, worry, thought, sadness, fear, shock is the normal human body’s emotional and mental activities, but long-term mental stimulation or sudden severe mental trauma, beyond the range of physiological activities, can cause the human body yin and Yang, qi and blood, organs, meridians dysfunction and cause disease. The main method of Chinese medicine for understanding and treating malignant tumors is to discriminate between evidence and treatment. The principle of discriminating between evidence and evidence is to comprehensively understand and analyze the disease and pay attention to the relationship between local and overall tumors. The main method of treatment for malignant tumors in Chinese medicine: supporting the positive and eliminating the evil. The method of helping the righteous: nourishing blood, helping yang, nourishing yin, benefiting qi, strengthening spleen, moistening lung, tonifying kidney, etc. The method of dispelling the evil: clearing heat, detoxifying blood, activating blood, siltation, softening hardness, dispersing knots, expelling water, resolving phlegm, eliminating ducts, draining swelling, dipping lung Generally speaking, in the early or middle stage of tumor or when the patient is in good health and the righteousness is not yet deficient, the main treatment is to dispel the evil, while paying attention to dispelling the evil without harming the righteousness, or making up for it with a big attack. In the middle and late stage, the tumor enlarges, there are lymphatic metastasis outside the adjacent organs or regions, the patient has less diet, the whole body is weak, and the positive energy of the organism is significantly depleted, so both attack and supplement are given. Commonly used treatment methods in Chinese medicine 1.Fu Zheng Pei Ben method – mainly used for positive deficiency, to support positive qi and cultivate vital energy drugs to treat deficiency. (1) Benefit the qi and strengthen the spleen method: mainly for tumor patients with qi deficiency, manifesting as fatigue, shaking white face, low voice, shortness of breath, spontaneous sweating, loose stools, weak pulse, pale or fat tongue with teeth marks and thin white tongue coating. Commonly used drugs are Astragalus, Radix Codonopsis, Ginseng, Radix et Rhizoma Ginseng, Atractylodes Macrocephala, Poria, Glycyrrhiza glabra, Radix et Rhizoma Huaiyang. Modern pharmacological research has confirmed that the drugs for tonifying the qi and strengthening the spleen have the effect of regulating the immune function of tumor patients, enhancing anti-cancer ability and inhibiting the growth of cancer cells. During chemotherapy, we can add some drugs that harmonize the stomach and lower the rebelliousness, such as Sharen, Hanxia, and Chen Pi, as well as drugs that nourish the kidney and fill the essence, such as Lycium barbarum, Cordyceps sinensis, Radix et Rhizoma chinensis, Bacopa monniera, and Cistanches, etc., which can reduce the gastrointestinal reactions and damage to hematopoietic function caused by chemotherapy. (2) Nourishing Yin and generating fluid method: It is the basic method to treat tumor patients with internal heat due to Yin deficiency and depletion of Yin and fluid as the main manifestation after radiotherapy. Symptoms include fever in the hands and feet, afternoon hot flashes, night sweats, dry mouth, dry throat, irritability, insomnia, difficulty in passing stools, red tongue, little or no moss, thin and feeble pulse, and other symptoms of deficiency heat. Commonly used drugs include American ginseng, southern ginseng, northern ginseng, asparagus, maitake, raw earth, elemental ginseng, dendrobium, smallpox powder, tortoise shell, turtle shell, yu zhu, yellow essence, lady’s mantle, and Zhi Mu. These drugs have the effect of nourishing Yin and clearing the lungs, nourishing Yin and increasing fluid and nourishing the lungs and kidneys. (3) Nourishing Yin and nourishing Blood: It is the basic method to treat tumor patients with Blood deficiency as the main manifestation. It is seen clinically as dizziness, dizziness, palpitation, insomnia, withered face, pale lips and nails, fatigue and weakness, thin pulse and pale white tongue. Commonly used in patients with advanced disease or those with anemia due to hematopoietic damage after chemotherapy. Commonly used drugs: Radix Rehmanniae, Radix Angelicae Sinensis, Radix Aconiti, Radix Paeoniae Alba, Radix Tortoise, Radix et Rhizoma Polygonati, Fructus Lycii, Radix Longan, Radix Ziziphi, Radix et Rhizoma Chicken Blood Vine, etc. It is often used together with qi tonic (Astragalus, Ginseng) and spleen strengthening (Atractylodes Macrocephala, Poria). Modern pharmacological research: it can prolong the existence of antibodies, regulate sympathetic nerve and endocrine function, relieve the hyper-metabolic state, protect the hematopoietic function of bone marrow, and increase the white blood cells, hemoglobin and platelets in the blood. (4) Nourishing the spleen and stomach method: a basic method for treating tumor patients with spleen and kidney yang deficiency as the main manifestation. Clinical manifestations are fatigue, shaky white face, low language, shortness of breath, spontaneous sweating, little food and loose stool, weak and feeble pulse, pale or fat moss, thin white moss, sunken and thin pulse, etc. Commonly used drugs: Radix et Rhizoma, Cinnamomum, Epimedium, Arctium, Locking Yang, Bacopa monniera, Boneset, Deer horn gum, etc. Modern pharmacological research: these drugs can regulate the abnormal metabolism of tumor cells, make them normalize and enhance the body’s ability to fight cancer. Some of them suppress tumors by improving the function of immune organs such as bone marrow and lymphatic system, spleen, etc. and enhancing the immunity of the body. (5) Activating blood circulation and resolving blood stasis method: The main manifestations of tumor are lump, pain with a fixed location, skin nail fault, blue or dull tongue, or petechiae, petechiae or bruised petechiae or dilated veins under the tongue, and string-like or astringent pulse. Commonly used drugs include: Trigonella, Curcuma longa, Rhizoma Chuanxiong, Salviae Miltiorrhiza, Radix Paeoniae, Safflower, Radix Angelicae Sinensis, Panax notoginseng, Peach kernel, Phyllostachys, Lingzhihua, Phellodendron, Boswellia, Myrrh, Leech, Phellodendron, Centipede, Scorpion, etc. Modern pharmacological research: blood activating and blood stasis removing drugs can weaken platelet coagulation, make cancer cells less likely to stay, gather and plant in the blood, improve microcirculation, increase vascular permeability, improve local hypoxia of tumor, and favor immune lymphocytes to reach tumor sites to play anti-cancer effects. (6) Heat-clearing and detoxification method: The treatment of tumor can not only directly inhibit or kill tumor cells, but also improve the immune function of the body to achieve the therapeutic effect. Clinical manifestations: fever, enlarged lumps, local burning pain, thirst, constipation or yellow urine, constipation or jaundice, yellow fur, red and vivid tongue, pulse count, etc. Commonly used drugs: Cyperus alba, Semen lanceolata, Semen lanceolata, Lobelia, Phellodendron, Serpentine berry, Bupleurum, Sansevieria, Ginseng, White hairy vine, Xia Gu Cao Cao, Tu Fu Ling, Tian Qi Zi, Fishy grass, Comfrey, Stinky peony, Qing Dai, Cyperus, Vine pear root, Astragalus, Huang Lian, Huang Bai, Honeysuckle, Crowberry, Wild chrysanthemum, Forsythia, Dandelion, Horsetail, etc. Modern pharmacological research: through antibacterial, bactericidal, against a variety of microbial toxins and other toxins, inhibit inflammatory exudation, proliferation, eliminate edema and inflammatory reaction. Some purging and detoxifying drugs have the effect of inhibiting tumor cells directly or indirectly, can improve the immune function of the body against tumor, and have strong anti-cancer activity. (7) Method of resolving phlegm and softening firmness: It is mostly used for nameless swelling and poison, not itchy or painful, phlegm nucleus scrofula, mammary mass, wheezing and phlegm sound, obstruction and accumulation of obstruction or diarrhea and edema, wheezing and phlegm, vomiting and vomiting, poor appetite, obscure tongue, greasy coating and slippery pulse. Commonly used drugs: Psidium guajava, Saponaria sp., Xia Gu Cao Cao, seaweed, kombu, raw oyster, corrugated seeds, Cyperus rotundus, Tian Nan Xing, Ze Qi, sea clam shells, Semen, Siberian silkworm, cat’s claw, white mustard seed, Bayberry, Arctium hebecarpa, Job’s tear, money grass, Mouton, Fang Wei, Poria, Huo Xiang, Perilla, etc., which can inhibit tumor cell growth and enhance human immune function. (8) The method of regulating qi and lowering rebelliousness: it is applicable to qi stagnation and rebelliousness caused by the loss of qi flow. Clinical symptoms include: chest tightness, chest and rib distension, stomach and abdomen distension, difficulty in swallowing, shortness of breath, cough, belching, vomiting, breast distention, shortness of breath and heaviness, with smooth or thin pulse and thin white fur. Commonly used drugs: August zha, orange luo, Chen Pi, Chuan Dong, sand, cardamom, Mu Xiang, Yan Hu Suo, Citrus aurantium, Citrus aurantium, betel nut, Su Stem, rose flower, moon flower, green calyx plum, sedum, whirlpool, loquat leaf, clove, descending incense. It can inhibit cancer cells and guide the transformation of cancer cells to normal cells. (9) Toxin attacking toxin method: the method of attacking the toxin of cancer with more toxic and stronger drugs. It is applicable to skin cancer, cervical cancer, head, face and limb tumors, penile cancer, esophageal cancer, stomach cancer, liver cancer, rectal cancer, etc. Commonly used drugs: Zanthoxylum, Dewberry, Scorpion, Centipede, Leech, Dung Beetle, Toadstool, Earth Turtle Worm, Xiong Huang, Strychnine, Croton, Cow’s Knee, Raw Semen, Raw Nan Xing, Aconite, Guan Hua, Euphorbia, etc. Modern pharmacology confirms that: most of them can kill cancer cells and have a strong effect of inhibiting cancer cells, and some herbs also have the effect of enhancing immune function.
