According to the Chinese Academy of Traditional Chinese Medicine (CACM) released on April 9, 2009, the “TCM Physique Classification Criteria” is the first document to guide and regulate the research and application of TCM physique, aiming to provide a basis for physique identification and the prevention and treatment of diseases related to TCM physique, health care and health management, and to make the physique classification scientific and standardized. The physical constitution is divided into nine physical constitutions, namely, pinghe, qi deficiency, yang deficiency, yin deficiency, phlegm-damp, damp-heat, blood stasis, qi yu, and special endowment.

How to adjust the body after determining the constitution? Experts from the TCM Physique Research Group point out that the physique can be adjusted. Physique is not only endowed by nature, but also related to nature. The stability of physique is formed by similar genetic background, age, gender and other factors can also make the physique show a certain stability. However, the stability of the physique is relative, the individual in the growth of the old life process, due to the environment, mental, nutrition, exercise, disease and other factors in the internal and external environment, will make the physique change. Body mass only has relative stability, but also has dynamic variability. This characteristic is the basis of the adjustable physique. Drugs and related treatments can correct the imbalance of yin and yang, qi and blood, and fluids of the body, which is the practical basis of the adjustable physique. Paying attention to the differences between different physique types and symptoms of diseases and the response to treatment with drugs is the concrete practice of individualized treatment and the implementation of the idea of “tailoring to the individual”. The treatment principle of “people-oriented” and “seeking the root of the disease” is reflected; early detection and intervention of the biased state of the body constitution, prevention of the cause of disease, pre-clinical prevention, and clinical prevention are carried out to achieve the regulation of the quality of the body to reject evil, regulate the quality of the body to prevent disease and regulate the quality of the body to prevent changes, so as to practice Chinese medicine “treating the disease before it happens”. For example, people with Yang deficiency physique who are afraid of cold can eat more warm Yang products such as beef, mutton, leek and ginger, less cold food such as pear, watermelon and water chestnut, less green tea, and also eat angelica ginger and mutton soup for individualized health management.
