Winter tonic has become a traditional folk custom. After the winter solstice, people buy all kinds of tonic products and medicines, thinking that winter is a good time to take tonic. There is a certain reason to consider winter as a good season for tonic. Winter is the season when everything in nature is collected, and the human body is no exception. Due to the low temperature in winter, the human body needs to consume more energy in order to keep the normal body temperature constant. In addition, people’s appetite increases in winter, and the body’s digestion and absorption of nutrients increases accordingly, so it is easy for the body to absorb and store the tonic at this time. At the same time, traditional Chinese medicine tonic is generally more warm, so it is suitable to be taken in winter. In order to correctly carry out winter tonic, we must pay attention to the following aspects: 1. Know your own physique Chinese medicine has the principles of treating diseases such as “deficiency tonic”, “real diarrhea”, “cold hot” and “hot cold”, etc. These principles are not only applicable to Chinese medicine for treating diseases, but also to winter tonic. When taking tonic, different methods of tonic should be used according to the different physical conditions of the target. In addition, it is necessary to distinguish whether the target of tonic is Yin or Yang deficiency. For those with Yang deficiency, sweet warmth should be used to benefit Qi, so that Yang can flourish, while for those with Yin deficiency, thick flavored products should be used to replenish Essence and Blood, so that Yin is sufficient. For those with yin deficiency and fire deficiency, although both use tonic, the former should use sweet and cool clear tonic, such as honey, lily, duck egg, buttermilk, duck, lotus seeds, rock sugar and other foods; the latter should use pungent and sweet warm tonic, such as cinnamon, lychee, beef, chicken, sea cucumber and other foods. In short, there should be a difference in the choice of tonic food, not to be confused. For people who are suffering from acute or infectious diseases, it is necessary to distinguish the nature of the disease when taking tonic. If the disease is caused by heat, cool food should be given, such as watermelon, fresh lotus root, etc. If the disease is caused by cold, warm food should be used, such as ginger, mutton, brown sugar, etc. If the disease is accompanied by bloating and indigestion, the main purpose is to eliminate food, such as some hawthorn, radish and other food. In short, tonic is not limited to eating tonic, all the health benefits, suitable for their own physical condition, are tonic.” The meaning of “secret, pass stool is called tonic” is that: people who are constipated, pass stool is also a method of tonic. 2, tonic to pay attention to the function of the spleen and stomach tonic to pay special attention to the function of the spleen and stomach. Chinese medicine believes that the human body to drink food digestion, absorption all depend on the normal function of the spleen and stomach, the spleen and stomach absorb the essence of the diet, the whole body, is the source of human nutrition. Therefore, the strength of the spleen and stomach has a very important role to play in overcoming disease and evil, coordinating the body’s yin and yang, strengthening the body, and restoring body functions. Generally speaking, in most disease processes, the appetite is mostly diminished when the intestinal function is weakened, and special attention must be paid to this. Therefore, even if the diet is suitable for the disease, it should be controlled appropriately, and should not be supplemented. Tonic will increase the burden on the spleen and stomach, so that it cannot be digested and aggravate the disease, or cause other diseases. Although some weak patients need to take tonic in their diet, because of the low function of the spleen and stomach and poor appetite, they should not be nourished with greasy and thick taste, but should be given light and easily digestible food to gradually enhance the function of the spleen and stomach. 3, out of the misunderstanding of tonic indiscriminately is the biggest misunderstanding of tonic, people always think that there is no harm to eat tonic, in fact, it is not. In fact, there is no harm in taking tonic. It is not advisable to take tonic indiscriminately without deficiency and to avoid deficiency without tonic. No deficiency indiscriminate tonic. Abuse of tonic without deficiency not only consumes drugs, wasting money, but also leads to the imbalance of yin and yang, the normal physiological function of the internal organs will be disturbed. Therefore, before taking the tonic, we must identify the reality of the deficiency, so as not to suffer the calamity of indiscriminate tonic without deficiency. Deficiency without tonic. Some weak patients, after taking tonic and supplements, the disease is not reduced, but aggravated or a series of adverse reactions such as dry mouth, dry tongue, insomnia, bloating, belching. One reason for this is that the patient’s spleen and stomach are weak, and the digestive and absorption functions are not sound, while many tonic medicines, especially blood and yin tonics such as Agaricus, turtle and turtle, are mostly nourishing and not easily absorbed, which easily stagnate in the stomach and intestines and produce symptoms such as indigestion. Another reason is due to improper supplementation. For example, patients with yin deficiency blindly use warm tonic medicines, which aggravate the existing yin deficiency symptoms. In addition, after a person suffers from a disease, to restore health, it is not possible to rely on tonic and supplements alone; to restore health, one should never rely on tonic and supplements. Weakness in the body can be due to congenital deficiencies, but also due to the loss of nourishment after birth. Such as dietary disorders, emotional and mental disorders, excessive room work, etc. Therefore, in addition to tonic, strengthen physical exercise, pay attention to dietary hygiene, maintain good health habits and mental state is very important, a rich and colorful social life is better than senior tonic, tonic.
