Under the guidance of TCM theory, TCM health preservation is to scientifically regulate the human body and maintain the health and vitality of life, following the changing law of biochemical collection of Yin-Yang and Five Elements. Psychological health preservation refers to the method of nourishing the heart, regulating the mood and life, so as to achieve the purpose of maintaining the body, reducing diseases, improving health and prolonging life. Health care products are popular terms for health care products and food. Article 3 of GB 16740-97 "General Standard for Health (Functional) Foods" defines health foods as: "Health (Functional) foods refer to a kind of foods that have the commonness of general foods, can regulate human functions, and are suitable for specific people to eat, but are not aimed at treating diseases." It is better to ask yourself than to ask others. Don't treat your life as someone else's reagent, be the master who controls your life!
