Patients often look at the prescription and ask, “How come there are no anti-cancer drugs such as half a lotus, white flowered snake tongue herb, centipede and whole scorpion in the prescription?” This statement is not an indication of how high the people’s level of Chinese medicine has become, but precisely reflects the patients’ misunderstanding of Chinese medicine. These drugs are all heat-clearing and detoxifying drugs, which have good therapeutic effect on cancer with secondary infection. The above Chinese medicines are just the tip of the iceberg. The above Chinese medicines are just the tip of the iceberg. Anti-cancer drugs are not only two types of drugs, namely, antipyretic drugs and anti-toxic drugs. First of all, cancer patients are in the state of deficiency, so treatment with antipyretic and anti-toxic drugs alone is likely to hurt their vital energy and worsen their condition. Chinese medicine treatment for cancer needs to be based on evidence-based treatment, and to support the positive and dispel the evil at the same time, including supporting the positive medicine such as benefiting qi and nourishing yin, nourishing blood and warming yang, and dispensing the evil medicine such as resolving dampness and dampness, clearing heat and detoxifying toxins, activating blood circulation and removing blood stasis according to the amount of dampness, heat and stasis (pathogenic factors), so as to form a prescription that takes into account both positive and evil. The treatment of cancer is not only to kill cancer cells, but also to protect the immune function of the body, including the normal function of all tissues and organs, which is what Chinese medicine calls positive qi. Combining the holistic view of Chinese medicine, which is to support positive energy to eliminate evil, with the local view of Western medicine, which is to kill cancer cells through surgery and radiotherapy, can effectively reduce the reaction to surgery and radiotherapy, relieve the pain of cancer patients, improve the quality of survival and prolong the survival period. Therefore, the combination of Chinese and Western medicine is the best solution in comprehensive treatment, and this can not be achieved by two types of drugs alone, such as heat-clearing and detoxifying drugs and fighting with poison. Secondly, the pharmacological research on in vitro inhibition of cancer cells by Chinese medicine shows that there are not only two types of drugs, namely purging and detoxifying drugs and attacking with poison. For example, the extracts of Hibiscus sabdariffa from Hibiscus sabdariffa; colchicine from Cichlidium spp.; three types of cedarine from Triticum aestivum and Triticum aestivum; indigotin from Qing Dai; and smallpox powder protein from smallpox powder are all good for various cancers. Among them, Xi Shu is a blood activator and smallpox powder is a yin nourishing medicine, both of which are not heat-clearing and detoxifying and attacking toxins with toxins. Among 1065 kinds of Chinese medicines, 329 kinds of Chinese medicines have cancer-inhibiting effect in vitro, accounting for 31% of the total, that is, nearly 1/3 of Chinese medicines have cancer-inhibiting effect, creating a new world for the development of anti-cancer Chinese medicines. Among the 329 kinds of Chinese medicines, there are 55 kinds of heat-clearing and detoxifying medicines, accounting for 17%. In addition to the familiar half-branch lotus and white flowered snake’s tongue, traditional Chinese medicines include Huang Lian, Scutellaria, bitter ginseng, raw earth, Dan Pi, red peony, comfrey, honeysuckle and vine, dandelion, big green leaf, Panax quinquefolium, Qing Dai, Tu Fu Ling, fishy grass, shot dry, shandoo root, white head, Qin Pi, etc. The above Chinese medicines with cancer-inhibiting effect have broader and better functions, so why not choose them? The next is 45 kinds of Fu Zheng medicine, accounting for 14%. Once again, there are 40 kinds of phlegm-softening drugs, accounting for 12%. There are half of the summer, South Star, orris, guavas, seaweed, yellow medicinal seeds, almonds, soursop, ginkgo, Yuan Zhi, Dou Shu, atractylodes, Hou Pu, Fu Ling, Yin Chen, sea clam shells, etc.. There are 33 kinds of poison and blood-stasis activators, each accounting for 10%. The former include strychnine, wolfsbane, chrysanthemum, castor bean, toad skin, centipede, scorpion, bee venom, snake venom, stigmaster, arsenic, etc. The latter include Chuanxiong, Salvia, Trigonella, Curcuma longa, tiger stick, saffron, frankincense, turmeric, cyperus, Panax notoginseng, Guanzhong, etc. The above five major Chinese medicine systems for cancer treatment only account for 63% of the total. In addition to the above major categories of herbal medicines, there are 18 kinds of anti-cancer herbs, 10 kinds of diaphoretic herbs, 13 kinds of warming herbs, 18 kinds of dispelling wind and dampness herbs, 14 kinds of anti-food and insecticidal herbs, 12 kinds of sedative herbs and 38 kinds of other herbs, which are often used in Chinese medicine prescriptions for cancer treatment. The correct TCM prescription for cancer treatment should be tailored to different functions and categories of Chinese medicines according to the diagnosis and treatment, and adjusted according to the changes of the disease. Especially during the treatment process, the prescription should be adjusted according to the different physical conditions of the patients.
