The difference between health tea and ordinary tea is that health tea pays more attention to the health care function of tea, and most health tea plays the role of medicine in the form of tea. Tea containing tea leaves or made from traditional Chinese medicines or raw materials with the same origin of medicine and food for health care is collectively called health care tea. The main advantages of health tea are convenience, quickness and instant, but the disadvantage may be that it is not as good as traditional tea. However, there are many alternative teas that lead to some functions. For example, a health tea named Lotus Qingfei independently developed by Yiling Pharmaceutical Co., Ltd. is mainly aimed at refreshing and nourishing the lungs.
