The difference between health tea and ordinary tea is that health tea pays more attention to the health care effect of tea, and most health tea plays the role of medicine in the form of tea. Tea containing tea or made of traditional Chinese medicine or raw materials with the same origin of medicine and food for health care is collectively called health tea. The main advantage of health tea is that it is convenient, fast and instant, and the bad place may be that it is not as good as the taste of traditional tea. However, there are many alternative teas leading some functions. For example, a health tea independently developed by Yiling Pharmaceutical Co., Ltd. named Lianhua Qingfei is mainly aimed at refreshing and nourishing the lungs.
