If it is small, the blood circulation is not good, and when it is extremely anemic, it disappears completely in half a month. There is a straight line on the nail, which is proof of overwork and overuse of the brain. At the beginning of the dangerous pathological state, the horizontal line is only exposed at the bottom of the nail, and gradually moves upward with the growth of the nail. People who are good at this can infer the possible period of the disease from the position of the horizontal line. 1, healthy people's nails are pink.

People over half a month are prone to high blood pressure and stroke; If the first month and a half is too small, it means that the blood pressure is too low. Most people who can't see the half-moon nails at all have symptoms of anemia or neurasthenia. At the same time, the color of the half-moon nails is milky white. Blue, suggesting that there is a problem with the respiratory system and it is easy to suffer from cardiovascular disease; Blue is a sign of poor blood circulation; Redness equals heart failure. Healthy people have a moderate figure. People who are smaller or disappear generally have poor digestive function, relatively weak body and are prone to fatigue. From the perspective of traditional Chinese medicine, if the crescent moon on a person's nails is radian 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 and its physical condition is not as good as before. It is indeed recorded in Chinese medicine that a person's heart function is good or not, which can be judged by the white crescent moon. Traditional Chinese medicine believes that the liver stores blood, and the quality of blood circulation will directly affect the heart function, while the liver is concentrated on people's nails. Generally speaking, people with white crescent moon are full of energy and have smooth blood circulation; The white crescent moon is small or not at all, but the mood is weak and the blood circulation may not be very good. The liver began to understand the eyes, the main reinforcement, and its flowers were in the claws. It shows that the rise and fall of liver blood can affect the rise and fall of fingernails. The following is more specific: (1) What is a half-moon mark? There are white arc marks under the fingernails. This is a half-moon mark, also called Little Sun. Nail half moon mark is the boundary between yin and yang meridians and the representative of human essence, so it is also called health circle. The development of semilunar scar is 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. The condition of half moon mark shows the information of human health. (2) The role of the half-moon mark Chinese medicine theory: Qi is not consumed by the liver but by blood, blood is not consumed by the kidney, and essence is not consumed by the bone but by the marrow. This is the origin of essence. Essence is also the source of vitality. The importance of the half-moon sign can be seen, because the information displayed is the essential state. Function of primordial qi: 1, nourishing the internal organs of the whole body. 2. Promote the normal operation of qi and blood in internal organs. 3. Resist foreign pathogens (immune function). 4. Longevity and anti-aging substances. 5. Genetic material. There is a saying in Chinese medicine: essence is strong and essence is weak, causing disease, essence is young and essence is exhausted. This shows that the essence of vitality is important. In daily life, it is beneficial to our health to restore energy and keep healthy in time. When energy is insufficient, protein is the first important supplement. Chinese medicine says: "essence is not enough to make it taste." That is to say, to supplement protein. High-quality protein should be neutral, such as milk, eggs, beans, fish, black food (nourishing kidney in case of black), seed food and embryo food. After a month of persistence, you can see the half-moon mark, which shows that your energy has been restored to a certain extent. (3) The normal half-moon mark number is 1, and the half-moon mark number of hands should be 8- 10. 2. The shape of the half-moon mark accounts for one-fifth of the nail. 3, the color of the half moon mark is milky white, the whiter the better, indicating that the energy is strong. (4) Abnormal half-moon mark 1, less half-moon mark, less half-moon mark, indicating that the worse the energy, the colder the constitution, that is, the weak immunity and cold hands and feet. 2. Three types of abnormal half-moon marks ① Cold bottom type-the less half-moon marks, the colder, and the cold type without half-moon marks. Cold type means that the yang in the body is weak and the yin is cold. This kind of people have low viscera function, slow blood circulation, fatigue, listlessness, poor absorption function, pale face, fear of cold in hands and feet, panic, lethargy, easy to catch a cold, repeated colds, gradual energy decline, physical decline, and even phlegm and blood stasis, phlegm-dampness nodules, easy to produce tumors. (2) Hot-bottom type-anything with a half-moon mark on the little finger belongs to hot-bottom type. The half-moon mark of a hot person is more than one-fifth of the nail. The increase of half moon marks indicates that the yang in the human body is relatively strong, the viscera function is strong, and the physical quality is good. However, in the case of illness, Yang is strong. This kind of people will have red face, irritability, irritability, dry mouth, large appetite, not afraid of cold, active, and even high blood pressure and blood sugar, which is easy to have a stroke. ③ Staggered type of cold and heat —— the place where the boundary of half moon mark is blurred and the color gradually approaches the color of nail body, which belongs to staggered cold and heat or imbalance of yin and yang. Early stage: the edge of the half moon mark begins to be unclear, such as shining. Mid-term: the half-moon mark begins to shrink. Late stage: the half-moon mark gradually decreases and disappears. 3. The half-moon mark area 1 half-moon mark area is less than one-fifth of the nail, indicating lack of energy and poor gastrointestinal absorption. If the semilunar scar suddenly darkens, shrinks and disappears, it often suffers from wasting diseases, tumors, bleeding and so on. There is no half-moon mark before the child develops. Adults have too much nightlife and sex life, and the half-moon mark will disappear and it is difficult to grow. ② When the half-moon mark exceeds one fifth, it is mostly cardiac hypertrophy, which is prone to cardiovascular and cerebrovascular diseases, hypertension, stroke and other diseases. 4, the color of the half moon mark 1 milky white-indicates normal, such people are full of energy, good physique and physical and mental health. (2) gray-said fine weak, affect the digestion and absorption function of the spleen and stomach, easy to cause anemia and fatigue. 3 pink-can not be distinguished from the color of nail body, indicating that the function of zang-fu organs is decreased and physical exertion is too large, which is easy to cause diabetes and hyperthyroidism. (4) Purple is easy to cause cardiovascular and cerebrovascular blood circulation, insufficient blood supply and oxygen supply, dizziness, headache and cerebral arteriosclerosis. (5) Black-more common in severe heart disease, tumor or long-term medication caused by drugs and heavy metal poisoning. (5) The relationship between the half-moon mark and the five fingers is 1, and the thumb half-moon mark-when the lung and spleen are pink, it means that the pancreas is not functioning well, and it is easy to catch a cold, repeatedly catch a cold, get tired, and get diabetes in severe cases. 2, the index finger half moon mark-when the stomach is pink, it means that the circulation of the stomach and large intestine is not smooth, and the appetite naturally declines. 3, the middle finger half moon mark-the pericardium is connected, when the mind is pink, it means that the spirit is over-stressed, and it is easy to be dizzy, headache, unclear thinking, brain swelling, insomnia and dreams. 4, ring finger half moon mark-when the endocrine is pink, it means that the triple energizer meridian running on the ring finger is abnormal, which is prone to physical decline and imbalance of Yin and Yang. People are prone to unspeakable discomfort, and women will get gynecological diseases such as irregular menstruation. 5, the little finger half moon mark-Guanlianxin kidney little finger is generally difficult to grow half moon marks, most of which are fever. When it is red, it is prone to serious heart disease.
