According to personal circumstances can drink tea, drinking tea has a certain value, do not force to drink, on the other experts found the following:$ China is the birthplace of tea culture, tea has a good medical utility, the Tang Dynasty that is, “tea medicine” term. Song dynasty Lin Hong compiled “mountain clear supply” in the “tea, that is, medicine,” the assertion. As early as in the “Qianjin food treatment” in the tea “taste bitter salty cold, cold, non-toxic” records. Tang Materia Medica” also pointed out that tea can clear the head and eyes, in addition to thirst, phlegm, digestion, diuretic, detoxification. Folk tea has long been “anti-cancer and anti-cancer” said. Modern research has shown that the main anti-tumor component of tea is tea polyphenols (TP), which is a biologically active component of tea, and the mechanism of TP’s tumor inhibitory effect has been reported in the literature to be related to TP’s ability to kill tumor cells, induce apoptosis, overcome multidrug resistance, increase sensitivity to chemotherapeutic drugs, and regulate immunity. Chen Xinyi et al. found for the first time that TP has obvious inhibitory effect on transplanted S180, EMT6 and A549 mouse tumors in the research funded by the National Natural Foundation of China, and one of the mechanisms for obtaining the effect is to down-regulate the expression of VEGF and bFGF, and up-regulate the expression of TIMP-2, so as to reduce the MVD of tumor tissues, and synchronous research also confirmed that TP can specifically act on tumor blood vessels, and has no obvious effect on microvasculature of normal organs and tissues. The simultaneous study also confirmed that TP could act specifically on tumor blood vessels, without significant effect on normal organ microvessels, indicating that TP is a specific tumor neovascularization inhibitor.
