China has a long history of tea culture, and is the first country in the world to cultivate and utilize tea. Open China’s five thousand years of civilization development history, almost every page of history can smell the fragrance of tea. Lu Yu “tea” said: “tea for drinking, from Shennong’s”, “Shennong’s taste of a hundred herbs, a day in more than 70 poison, get tea to solve it”, it can be said that China’s first discovered antidote to poison is tea. Modern science found that the active ingredients of tea is mainly tea polyphenols. Tea polyphenols have a strong antioxidant and eliminate the effect of free radicals, and excessive oxidation and excess free radicals has been considered an important factor leading to the development of cancer. In addition, tea polyphenols can effectively block the synthesis of carcinogens such as nitrosamines, and have a direct role in killing cancer cells. Animal experiments have found that as long as two to three cups of tea a day, it has a very good cancer prevention effect. In particular, it has a clear effect on common cancers such as stomach cancer, intestinal cancer, breast cancer, prostate cancer and thyroid cancer. Therefore tea is always considered as the most suitable drink for tumor patients. In terms of the production process of tea, it can be divided into green tea, black tea, black tea, yellow tea, white tea, green tea and flower tea. Among them, green tea is unfermented tea, fully fermented tea is black tea, semi-fermented is oolong tea and yellow tea, and black tea is post-fermented tea. From the point of view of the yin and yang of food, the fermented tea is hot or neutral, easy to absorb after entering the belly, and does not damage the yang of people. Unfermented green tea is cold in nature, and drinking more will damage the body’s yang energy and cause gastrointestinal discomfort, so not anyone is suitable for drinking green tea. In general, young female thyroid tumor patients are depressed and easily sullen, so the important principle of conditioning for such patients is to de-stress the liver and qi, and lift the depressed body. The most important thing is that the patient should be able to get rid of the depression, and the various flower teas are more suitable, especially some mixed flower teas such as rose puerh, chrysanthemum oolong, three flower tea are very good tea products, usually can drink more. In addition, for women with bowel problems, a cup of pu-erh tea after meals is also a very good drink to cleanse the bowels. Every morning you can also drink the right amount of green tea, such as Longjing, Mao Feng, Biluochun are very good between-meal drinks, the most suitable for women who are prone to fire. And male thyroid tumor patients are mostly due to a diet too oily and greasy resulting in internal circulation disorders, so to be especially recommended is black tea, black tea in Yunnan Pu’er and Anhua black tea are very good varieties, it is recommended that you can usually drink more. But some people are not used to the taste of fermented tea can also try semi-fermented oolong tea and yellow tea. Dahongpao, Tieguanyin, frozen top oolong, phoenix single fir, etc. are very good anti-food and fat-clearing drinks, not only anti-cancer, but also can effectively reduce blood lipids, protect blood vessels, reduce the chances of atherosclerosis, very suitable for male patients to take. As for the elderly thyroid tumor patients, most of them have tumor growth due to the weakness of the spleen and stomach, so the most suitable is black tea, which is also rich in tea polyphenols, but its mild nature does not hurt the stomach, and the stomach nourishing effect, very suitable for the elderly to drink. And the elderly are mostly cold body, is not suitable for frequent consumption of cold nature of green tea. Dr. Wu has also seen elderly patients, heard that green tea anti-cancer drink every day, the result of drinking a face full of black gas, not only did not drink away the tumor, but also drank a stomach ulcer and diarrhea. The way to drink tea also has to be careful, can not drink a lot at once, it is best to drink three sips at a time, but more is not conducive to absorption. The time to drink tea is also very delicate. Drinking tea immediately after eating is a habit that is not conducive to health, especially after eating high protein food drink tea, tea contains tannic acid will meet with protein, so that intestinal peristalsis slowed down, easy to cause food accumulation difficult to eliminate. For people with a cold body, the harm caused by drinking tea at this time is even greater. The morning is suitable for drinking black tea, especially from 9:00 to 11:00 in the morning (Si) is the spleen meridian running time, drink some black tea black tea for the spleen and stomach to provide the energy needed for digestion and absorption, eliminating food accumulation, not allowing excess material to remain in the body, the most suitable for people who want to lose weight. 3:00 pm to 5:00 pm (Shen) is the bladder meridian running time, this is the right time to drink oolong tea, clearing the water channel, drainage of stool just at the right time.
