The main reason why winter tonic is so popular and respected by the general public is that it has two main characteristics, namely tonic for deficiency and cure for diseases. Traditional Chinese medicine advocates winter tonic, because the winter climate is cold, the natural flora and fauna are in a state of collection and hibernation, the classic work of Chinese medicine “Yellow Emperor’s Classic of Internal Medicine” says: “March is the month of winter for sealing”, that is to say, winter is a good time to nourish the essence and store the sharpness, the human body is also in line with the changes in nature, when the human skin coup is more dense, less sweating, the nutrients consumed can be easily stored. This time, the skin couples are more dense, less sweating, the intake of nutrients is easy to store up, in addition, the appetite of people in winter is also more vigorous, so it is the best time for tonic. Modern medical research also shows that the human body’s metabolism slows down in winter, so proper nourishment at this time can coordinate and improve the physiological functions of human organs, enhance immunity, and achieve the effect of disease prevention and fitness. Therefore, the cream is generally taken within a month and a half from the winter solstice to the spring, or more relaxed from the frost to the spring equinox of the following year. The Yellow Emperor’s Classic of Internal Medicine says: “The spirit is cured when the yin is calm and the yang is secret”; “If it is deficient, it should be tonified, if it is real, it should be diarrhea, if it is cold, it should be hot, if it is hot, it should be cold”; “Do not be deficient, if it is deficient, if there is excess, there is deficiency”. These words mean: the balance of yin and yang in the human body is a healthy state, and the prescription of Chinese medicine legislation should be supplemented, diarrhea, warmth and coolness according to the different conditions of deficiency, actuality, cold and heat of the subject, so that the yin and yang can be balanced and restored to health, and never the other way around, destroying the balance of yin and yang in the body or aggravating the original imbalance of yin and yang. This is the summary of practical experience and a basic principle of Chinese medicine in the process of disease prevention and treatment for thousands of years, contrary to this basic principle, it will damage health and produce disease. In recent years, the author in the insomnia specialist clinic on nearly 4,000 cases of insomnia clinical characteristics of the survey found that today’s insomnia patients are purely deficient in few, the clinical performance of these patients are mostly seen in bed at night difficult to sleep, restless sleep, wake up early after difficult to fall back to sleep, daytime dizziness, head swelling pain, dry mouth, bitter mouth, brain ringing, tinnitus, panic, irritability and other hyperactive symptoms, according to the Chinese medicine dialectic most of them are real or real deficiency Moreover, most modern people are not undernourished, but over-nourished or nutrition structure is unreasonable, causing the loss of balance between the body’s yin and yang qi and blood, so insomnia patients must not be indiscriminate tonic, committing the “false false real” precautions, disturbing the balance of the body’s yin and yang, aggravating the insomnia disease. Therefore, the winter tonic for insomnia patients is very delicate, not just take some tonic, health products can be, tonic to be reasonable, to “dialectical tonic”, what is lacking, what to fill, never indiscriminate tonic indiscriminately served, otherwise it will be counterproductive. The author saw many insomnia patients in the insomnia specialist clinic every spring, is due to incorrect tonic in winter, after the beginning of spring, in addition to restless sleep and dream disturbances aggravated, but also dizziness, dry mouth, body heat, heartburn, chest tightness, nose bleeding, dry stool and other uncomfortable symptoms, which are caused by the wrong tonic. Therefore, the winter tonic for insomnia patients, I advocate must be under the guidance of insomnia specialist physicians, should not buy their own in pharmacies or supermarkets, or blindly follow the recommendations of those who “sit in the doctor”, and take the initiative to indiscriminately tonic. Specialists should also make holistic considerations according to the different physical, medical, work, living conditions, thoughts and emotions of different subjects, and prescribe creams or recommended supplements based on the evidence, so that the tonic will not make the money, the body does not get the benefit, but rather aggravate the disease and increase the pain.
