First of all, the half-moon radian of nails accounts for one-fifth of the total number of nails, which is a normal proportion, indicating that nails are in good condition. Whether the half-moon arc is too small indicates that the digestive function is poor, and it is too large or over-proportional, indicating the possibility of hypertension or stroke. Most people who can't see with ten fingers suffer from anemia, neurasthenia and low blood pressure. If the half-moon arcs of ten fingers are too large at the same time, it means that the body has lost its compensatory function and suffers from chronic diseases.
Second, if the streaks are small and numerous, it indicates long-term chronic digestive system diseases, such as gastroenteritis, colitis, stomach diseases and so on. If the horizontal stripes are deep, it means that you have serious digestive diseases, and the more serious, shallow and chronic gastrointestinal diseases are. If the stripes are raised, it means that there is something wrong with the heart, liver and lack of vitamins A and B.
Thirdly, the appearance of black spots on nails is one of the manifestations of gastrointestinal tract. Patients with cardiovascular and cerebrovascular diseases may also have this situation, because nails are often in an ischemic state. The most serious situation is that the black spots on the nails not only exist, but also affect your feelings and make you feel pain. The shape of black spots is getting bigger and bigger, and the color is getting darker and darker. In this case, it is possible to form melanoma, which develops from nevus and needs to go to the hospital as soon as possible.
The fourth kind is long nail white spot. According to the new understanding of sex by the World Health Organization, 80% patients with kidney deficiency will find white spots on their nails at an early stage. But Chinese medicine believes that the liver stores blood, the kidney stores essence, and the liver has claw flowers. Nails can predict whether the liver's qi and blood are sufficient and whether the essence and blood are homogeneous, and the two will affect each other. Finding some white spots on nails may mean that the blood is not enough to maintain normal peripheral microcirculation, and the internal organs themselves can be considered as kidney deficiency due to insufficient blood supply from superficial microcirculation. ?
