It is difficult to nourish hot pot by directly adding Chinese herbal medicines. Chinese herbal medicines with health-care and nourishing effects generally need a certain decocting time and technological process to achieve their health-care effects. It doesn't mean that, like some hot pot restaurants, raw herbs such as longan, cinnamon and Amomum villosum are directly added to the soup, which is to nourish the hot pot. Traditional Chinese medicine believes that the movement of qi and blood in human viscera is closely related to the climate change in nature. "Use cold to stay away from cold, use heat to stay away from heat". When using cold medicine, you should avoid cold winter or cold environment, while when using warm medicine, you should avoid hot summer or warm and dry environment. People's physical age is different, and there should be differences in tasting hot pot containing traditional Chinese medicine. For example, children's physique is delicate, and the choice of raw materials cannot be hot and cold. Many elderly people have insufficient liver and kidney, so it is not appropriate to use warm and dry drugs. Pregnant women are afraid of fetal gas and should not use products that promote blood circulation smoothly. For example, people suffering from hypertension, chronic pharyngitis, stomatitis, stomach problems, ulcers, skin diseases, hemorrhoids, anal fissure, frequent nosebleeds and gingival bleeding, and people with "hot constitution", it is best not to eat nourishing Chinese medicines containing warm ingredients. There are certain differences in climatic conditions and living habits, as well as physiological activities and pathological changes of human bodies in different regions. Some are located in humid places, such as hot pot in southwest China, which is warm, dry and spicy, and some are located in cold places, such as northeast China, which is hot and greasy, while south China is cold and sweet. Therefore, we should pay attention to these objective factors when choosing the ingredients of hot pot medicated diet, and choose Cordyceps militaris, Lycium barbarum and other foods for nourishing. Medicinal materials have not been professionally treated, and most of them have the function of removing fishy smell, removing fishy smell or seasoning. The health care and nourishing function is not as great as some merchants say. In addition, the hot pot should be cooked properly, and the hot pot should not be undercooked or overcooked. Overcooked dishes can not effectively kill pathogenic bacteria or eggs carried on the surface, which is easy to cause digestive system diseases; Over-cooked, the vitamins and amino acids in the dishes will be destroyed, and at the same time, they will lose their due umami flavor. Some people especially like to eat spicy food, which is too numb, and will make your lips lose consciousness and can't taste; Too spicy, it will stimulate the gastric mucosa, induce gastric cancer and unexplained skin diseases. Many people like to drink beer and eat hot pot. You know, the substances in hot pot soup are transformed into uric acid in the body, and beer can distribute uric acid in human joints or soft tissues, leading to gout and even serious complications such as kidney calculi and uremia. Eat soup early. Eat hot pot and drink soup as early as possible, otherwise the longer you rinse it, the higher the content of harmful residues such as nitrite in the soup.
