The crescent moon on the nail is related to health, which basically reflects the nutritional status and has a lot to do with digestion and absorption. The development of semilunar scar is influenced by nutrition, environment and physical quality. After a long period of good digestion and absorption, the half-moon mark will be blurred, reduced or even disappeared. Half moon mark (crescent moon) is a white arc, which usually appears in the lower fifth of nails.
In general, the crescent moon can neither be too small nor too small. If the crescent moon disappears or shrinks obviously, it has the greatest clinical significance, indicating that the overall health condition is not good recently, and it needs to be adjusted by taking some drugs orally or changing diet and living habits. The size and width of the new moon generally can't reflect the health status, but discoloration can indicate some diseases.
The crescent of nail, also known as nail matrix, is the growth area of nail. Generally white, it consists of 2 ~ 3 layers of basal cells. The proximal nail matrix forms the back deck and the distal nail matrix forms the middle deck. Everyone has it, but some people can see it, and some people can't see it because they are covered with skin. The size and width of nail material can't reflect the health status, but the discoloration of nail material, such as turning red, can be caused by congestive heart failure and rheumatoid arthritis. The crescent of nails is sky blue, which is very common in Wilson's disease.
Is nail without crescent moon a sign of bad health? Chinese medicine and western medicine have completely different ways of looking at problems. Chinese medicine believes that the crescent moon on the nail is an important indicator to measure a person's health. In the field of traditional Chinese medicine, the number, shape and color of nails and crescent moons can reflect a person's physical state. Generally speaking, the more crescent moons, the better the physical condition, the healthier the body, and the less crescent moons, the less healthy the body.
Chinese medicine believes that having more than eight crescent moons basically shows that people are healthy. The more beautiful and shiny the crescent moon, the healthier people are, and the less beautiful and dim the crescent moon, and vice versa. Chinese medicine also believes that it is very helpful to eat some nourishing herbs in daily work and life. As long as enough attention is paid to health, the crescent moon on people's nails will get better and better, and the crescent moon will get healthier and healthier.
