Crescent on the nail A healthy nail should be smooth, rosy, shiny, moderately thick, well-proportioned, unbiased, tough and brittle, with no vertical and horizontal grooves on the nail surface and a half-moon shape at the nail root (nail). Failure to meet any of the above standards may indicate that there is something wrong with your body. So, how should we judge specifically? Pi Xianming said, if you want to infer your physical condition from the crescent moon, you must first know what a healthy crescent moon looks like. Generally, the crescent on the fingernail should account for about 1/5 of the fingernail, and more than four fingers in 10 should have crescent, with clear edges. Chinese medicine believes that if the crescent radian on a person's nails is appropriate and shiny, it means that this person is full of qi and blood; If the crescent moon becomes smaller or gradually disappears, it means that the human body's qi and blood are declining, the blood circulation is not good, and the physical condition is not as good as before. Especially when there are obvious changes suddenly, or abnormal performance for a long time, we should pay special attention to it. Those people whose new moon is too small or too big say that they have some physical abnormalities or diseases. Too many people say that they are often in a state of anxiety and tension, which is more common among mental workers; Patients with gastrointestinal ulcer should be careful of gastric ulcer; Patients with cardiovascular diseases should be alert to cerebral hemorrhage. People whose fingernail crescent is too small or disappears generally have poor digestive function, relatively weak body and are prone to fatigue. If they have gastrointestinal diseases, they should beware of duodenal ulcer. Of course, the determination of the disease needs to be combined with other symptoms and medical examination, and finally the doctor makes a diagnosis. Because the development of crescent moon is influenced by nutrition, environment, physical quality and other aspects, according to the principle of "essence is not enough to supplement taste" in traditional Chinese medicine, high-quality protein, such as milk, eggs, beans and fish, can be supplemented. And black food, such as black rice, black fungus and some seed foods, and increase exercise appropriately. 2. If you are too tired, your nails will have vertical stripes. Ideally, there should be no vertical and horizontal grooves on the nail surface. Therefore, once it is found that its surface becomes rough, dull, and even has obvious longitudinal stripes, it feels like a ravine, which may mean that your body is in a state of fatigue recently, which may lead to problems such as physical weakness, persistent mental fatigue, and decreased immunity. In addition, lack of vitamins or trace elements can also lead to vertical stripes. The development of nails is influenced by many factors, especially the obvious vertical stripes on nails are closely related to diet, lifestyle and age. For example, people who often stay up late and lose their vitality are prone to vertical stripes on their nails. Of course, some young people are caused by colds and pneumonia. If this happens to middle-aged and elderly people, it is mostly because of old age, physical decline, and physical consumption is not easy to recover in a short time. Therefore, the diagnosis of specific diseases should be combined with other symptoms and the diagnosis of doctors. First of all, we should pay attention to developing a good lifestyle. In addition, through dietotherapy, we should eat a diet rich in high-quality protein, such as milk, eggs, beans and fish. At the same time, taking vitamins, zinc, iron, calcium and other trace elements to regulate our body functions, the vertical lines on the nail surface will gradually disappear.
