In fact, in ancient China, due to the agricultural society in the past, the labor expenditure was more, but the nutrition supply was often insufficient. In spring, summer and autumn, physical strength is often overdrawn. Therefore, the essence of the whole body should be hidden in winter to repair the function of the internal organs. The ancients observed the changes of the earth's magnetic field and temperature. By the winter solstice, they should start to follow the laws of nature and preserve Yin and Yang, so that the body's Yin and Yang can be comprehensive. After the Yin and Yang are unobstructed, there will be no internal injury of Yin and kidney qi.

Traditional Chinese medicine is called the theory of correspondence between man and nature, which means that people should adjust their lives according to the seasons. The solstice in winter is the most important time point for the transformation of Yin and Yang. Winter is the season of "latent gas reservoir" and the best time to maintain and accumulate energy. Traditional Chinese medicine theory holds that people should hide more things to ensure that they have enough essence to drive next year's activities, so winter tonic is to prepare for the severe winter. At this time, the yang in the human body is strong, and it is the easiest to absorb foreign nutrition, which can better nourish the body.

Does everyone have to take supplements? Of course not.

Traditional Chinese medicine pays attention to dialectical treatment, that is, dialectical treatment according to different constitutions. Different constitutions have different corresponding tonic formulas, dosages and ingredients. For example, every winter, some people are particularly afraid of cold, and some people are not afraid of cold. Why? The most direct reason is the difference in constitution: people who are afraid of cold are mostly yang-deficient constitution, while those who are not afraid of cold are mostly yang-filled in the body. Generally speaking, people who suffer from chronic diseases and belong to the constitution of yang deficiency need long-term tonic, which can only be supplemented in the spring; People who generally don't need a big tonic can concentrate on tonic in three to five days.

Some people may ask: Why do China and several neighboring countries engage in tonic, while western countries generally do not have this custom? Without his ears, it is still the reason of constitution. In Asian countries, it is generally a plant omnivore, while in the west, it is mainly meat and high-protein food. In addition, thousands of years of differences in culture, customs, environment and concepts have fundamentally changed their physique. Just like women in Asian countries have to be confined to their confinement, they can't touch cold water, see the wind, eat cold drinks or carry heavy loads during the confinement, but in the west, they generally don't do this. After giving birth, they should eat and drink. Of course, if West Renye Fang learns from Asia, can it? Of course, but we still need to treat it according to syndrome differentiation and prescribe the right medicine.
