Is it true?/You don't say. It is a lie that the crescent moon on the nail represents health.

Hello! Half-moon mark refers to the white half-moon shape under the nail 1/5. Some people call it the health circle and think it is the representative of human nature. The development of semilunar scar is deeply influenced by nutrition, environment and physical quality. When the digestion and absorption function is not good, the half-moon mark will be blurred, reduced or even disappeared, so the half-moon mark can reflect the healthy and evil state of the human body and infer the quality and prognosis of the disease. It is also said that the crescent moon on the nail is a "barometer" of human health.
