Tea has been the top grade of health care since ancient times. Drinking tea in different seasons has different effects on human body. In the cold winter, a cup of hot tea can not only drive away the chill, but also make people healthier. Different winter health tea has different benefits to human body. Black tea can prevent influenza, West Lake Longjing tea can purge fire, and scented tea can eliminate depression. Drinking tea in winter can refresh the mind, help digestion and stimulate appetite. However, Wang Jinyong believes that the premise is to choose products with guaranteed quality, and it is best for consumers to know the origin or production enterprise of tea when buying. As for the "organic" and "pollution-free" advertised by many enterprises, he believes that in addition to knowing the logo, it is also necessary to identify the origin of tea. "According to the traceability system of organic tea, consumers can trace the product manufacturer, picking block and production date. Therefore, if possible, it is best to know some tea gardens in advance. From the perspective of tea garden management, organic tea gardens use artificial weeding instead of herbicides, so weeds can be seen no matter how they are removed. There are many weeds in our Yangdingmao tea garden. In my opinion, it is not tea trees that compete for fertilizer and water, but grass that keeps water and fertilizer. Young grass is a favorite food of insects, which reduces the insect's eating of fresh tea leaves. Non-organic tea gardens do not use herbicides and fertilizers, and almost no grass grows in the tea gardens. "From the soil point of view, the organic tea garden land is soft, and the land with long-term application of chemical fertilizers and various pesticides is hardened; From the appearance of tea trees, organic tea leaves are thick and non-organic tea leaves are thin; Insect eyes are common in fresh leaves of organic tea gardens, and spider silk is common on tea fir. Because of the large use of pesticides in non-organic tea gardens, almost no insects can be seen. In winter, the climate is dry, and people like to eat greasy and spicy food, so getting angry has become a health problem that puzzles many people, and brings constipation, dry mouth and even aphtha. At this time, you can turn to West Lake Longjing Tea, a winter health tea. West Lake Longjing tea is unfermented tea, which is cold and can clear heat. Therefore, it can remove fire, promote fluid production to quench thirst, promote digestion and eliminate phlegm, accelerate the healing of mild gastric ulcer, reduce blood lipid and prevent arteriosclerosis. Therefore, people who are prone to get angry, people who usually like smoking and drinking, and obese people (usually with real heat constitution) are more suitable for drinking West Lake Longjing tea, a winter health tea; However, people with stomach cold and deficiency cold should not take West Lake Longjing tea, a winter health tea.
