Chinese medicine refers to physical weakness as body deficiency, and the deficiency of qi, blood, yin and yang of disease as deficiency evidence. Winter tonic is one of the characteristics of TCM. In the Nei Jing, it is said that the human body should nourish yin in autumn and winter, and that the yin essence should be used for the longevity of the human body. It also means that people should follow the natural changes and live in harmony with the natural law of growth and collection. This is the embodiment of the idea of “Do not go against the natural time, it is the best treatment” in the treatment of autumn and winter. The use of poultices is a more appropriate form of tonic. With the change of seasons, it is now the cold dew season, when the temperature drops and everything is gradually slaughtered, it is time for winter tonic. The important principle of winter tonic is to identify the type of deficiency, whether it is qi deficiency or blood deficiency, yin deficiency or yang deficiency, or whether it is qi-yin deficiency, qi-blood deficiency, etc., so that targeted tonic can be made. Improper winter tonic can also have various side effects. Clinically, many people have symptoms such as chest congestion and vomiting, abdominal distension, diarrhea, loss of appetite, dry mouth, dizziness and discomfort after taking creams in winter, which are all caused by the lack of the right remedy, the lack of a holistic concept. “If you take tonic, you must know how to take tonic. There is a way to take tonic, which has a strong target and profound connotation. Under the leadership of Prof. Yan Dexin, our hospital advocates that the balance of yin and yang should be the outline and the fluidity of qi and blood should be the objective. The purpose of tonic is to regulate the deficiencies of the internal organs, yin and yang, qi and blood, and to restore the balance of the body, which is called “Yin and yang are secret, and the spirit is healed”. Balance is the most basic main idea of Chinese medicine to maintain health and cure diseases. If the supplement is surplus, the real will often be counterproductive, emphasizing that supplementation should be based on the outline of diagnosis and treatment, following the principle of what is lacking. In the use of medicine, we emphasize the combination of dynamic and static, especially with the products that transport the spleen, in order to facilitate the absorption of the cream formula and play its curative and tonifying role. The selection of medicine for the cream formula is appropriate for each person, and it should be used as a flat tonic, a moderate tonic, a clear tonic, a warm tonic and a harsh tonic, but it must also be used with drugs that regulate qi and blood according to the nature of the disease. It is also a method of tonic, so that “blood vessels are connected and diseases cannot be born”.
