With the improvement of people’s living standard, health care prescriptions and medicinal meals of Chinese medicine have been familiar to people. Patients with malignant tumors are often mixed with deficiency and reality, cold and heat are not clear, if they do not distinguish between red and white, they will aggravate the imbalance of yin and yang, qi and blood in the body, and the function of internal organs, which not only cannot strengthen the body, but also may worsen the disease, so they must be used under the correct guidance of doctors. The first thing to do is to distinguish between cold and heat and deficiency. According to the principle of traditional Chinese medicine, “if it is deficient, it should be tonified; if it is real, it should be diarrhea; if it is hot, it should be cold; if it is cold, it should be hot”, the prescription should be selected and used. Secondly, we should identify the yin and yang. We take yin and yang as the outline, for example, people with yin deficiency can consume sweet, cool, nourishing and nourishing tonic products, such as Ganoderma lucidum, turtle, American ginseng, dendrobium, lily of the valley, yellow essence, pollen and so on. Yang deficiency body people should take warm Yang products, such as deer antler gum, codonopsis, longan meat, walnuts, etc.. Again, medicinal food therapy should be guided by the theory of Chinese medicine, pay attention to the identification of the material, according to the person because of the disease, according to the time and place, flexible selection of food and medicine. Such as angelica ginger lamb soup to nourish the blood, warm the Yang and disperse the cold, can be used for Yang deficiency cold condensation of abdominal pain. Medicine and food are of the same origin, and proper supplementation can remedy the bias and harmonize the internal organs, so as to play a better health care role in the health of tumor patients.
