Because the function of tea is different, the choice of tea is different. For example, black tea nourishes the stomach, green tea refreshes, oolong tea reduces weight, Pu 'er tea helps digestion and so on, so friends should choose tea according to their physical needs or personal preferences, so as to achieve good physical and mental health. In recent years, the health care effect of tea has been widely concerned. Materia Medica says: "All kinds of medicines are the medicine for all diseases, and tea is the medicine for all diseases." It is also a great affirmation of the efficacy of tea. Because tea contains not only basic nutrients, but also chemical components beneficial to human body, such as tea polyphenols, caffeine, tea polysaccharides and so on. Active substances such as tea polyphenols and catechins can keep blood vessel elasticity, eliminate arterial vasospasm and prevent blood vessel rupture. Tea is a national drink, and China people's tea drinking culture can be traced back to thousands of years ago. Although it is well known that drinking tea is good for people's health, every good thing has two sides, and drinking tea is no exception. Of course, drinking tea scientifically is to achieve the goal of health.

Tea polyphenols and oxidation products in tea help to absorb some radioactive substances. Therefore, drinking tea regularly can play a good role in preventing radiation damage. If there are pesticide residues in the tea used when making tea, it will also have an impact on health. In addition to buying tea from reputable merchants, you can pour out the first brewed tea when making tea, and open the lid when making tea, so that some pesticide substances will evaporate with water vapor. The first is choice. Do you choose tea that is comfortable after drinking or tea that satisfies the taste buds? Although good tea will taste good, good tea is not necessarily good for your health. New tea drinkers can easily go into a misunderstanding if they don't know how to feel with their bodies.

Tea is most afraid of moisture, mildew and odor. The best preservation containers are tin bottles, porcelain jars and colored glass bottles. Secondly, choose tin cans, wooden cases, bamboo boxes, plastic bags and cartons. The container should be dry, odorless and clean. Tea containers should be placed in dry and ventilated places, not in damp, high temperature, unclean and exposed places for a long time.
