On the Half Moon Mark from the Perspective of Traditional Chinese Medicine
According to the theory of traditional Chinese medicine, claws are flowers of tendons, except blood, qi is not consumed by the liver as blood, blood is not consumed by the kidney as essence, and essence is not consumed by the bone as marrow.
This is the origin of essence. Essence is also the source of vitality. Because the information displayed by the half moon mark is the condition of essence and blood gas, its importance can be seen.
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 good for your health to recover in time and maintain your health. When energy is insufficient, protein is the first important supplement.
Chinese medicine says: "Jingxue 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 half-moon marks on your nails, indicating that your energy has been restored to a certain extent.
Looking at the Half Moon Mark from the Perspective of Western Medicine
The half moon mark of western medicine is actually a part of nail bed, which grows to the bottom of methyl. It is a "bed" for growing nails, which supplies nutrients needed for nail growth and belongs to connective tissue. The nail bed is rich in blood vessels and nerve endings. When the blood circulation of the human body is normal, the blood supply at the nail tip is sufficient, the nail grows faster, and new nails are constantly growing.
The new nail body is not aging, so the color is lighter. It decomposes rapidly in the middle of nail bed, and the growth speed on both sides decreases, forming a half-moon shadow pattern. When the growth is fast, the half-moon arc is large, and when the metabolism is low, the half-moon arc is small or even not obvious. When some cardiovascular diseases occur in human body, when the blood supply of finger tip is damaged, and when the growth rate of nail body is lower than the aging rate, there will be a decrease or no half-moon mark. From this point of view, when people observe the half-moon marks on their nails, they can roughly understand their current health status through the manifestations of the half-moon marks.
Half moon mark position: an arc near the white area of the nail root.
Error state

Whether there is a crescent moon is not a criterion for judging health.
The scientific name of crescent moon is half moon or half moon mark, which is a natural phenomenon formed in the process of nail growth. The methyl group marked in the picture below is a production base of keratinocytes, which constantly creates new keratinocytes and keeps nails growing.
The newly produced keratin cells are still fresh, round and white. These newborn cells will push out the cells of the previous generation. When we squeeze into the nail root, the cells of the previous generation are squeezed more and more flat, die gradually, and start to harden at the same time (and because we are not in the nerve range of methyl, nail cutting will not hurt).
When the previous generation of cells entered the visible part of the nail bed, most of the keratin cells had been "squeezed" white and translucent, and they were as hard as small shields, shouldering the heavy responsibility of protecting the nail bed.
Because the growth rate of methyl decreases from the center to both sides, the time required for keratin cells to become translucent will not change because of different positions, so this white and translucent arc boundary is formed. If the white arc just comes out, it is half moon, which is what we call crescent moon. Look, the crescent moon is just a nail without complete keratinization.
Some people may be shy to hide for half a month because of the backward methyl group or the slow growth of nails (born, not caused by disease). Therefore, there is only an invisible new moon, and there is no non-existent new moon. But it's good not to see the crescent moon, which means that all your exposed nails are hard and can protect your nail bed. Those who are born without new moons or with fewer than eight new moons can still live a very healthy life.
Labor-loving nails grow fast. Thumb is a five-finger model worker, nails wear quickly and naturally grow fast, so the crescent moon is easy to be pushed out. This explains why most people's thumbs are crescent-shaped, because the thumb is used very frequently.
The little finger doesn't like labor more than the other four fingers, so the growth rate of the little finger nail is slower than the other four fingers. So the little finger crescent is rare. This is probably the origin of the phrase "eight crescent moons are just right, 10 crescent moons hurt the body".
But in fact, there is no scientific basis for this statement, because people who play the piano and violin often use the little finger more frequently than ordinary people, and the growth rate of the little finger nails is accelerated, so the crescent moon will also stir up. Some people's nails are born to grow fast, so the little finger will have a crescent moon.
Relationship with five fingers
edit
1. Thumb crescent-related to lung and spleen
The half-moon mark on the thumb is pink, indicating pancreatic dysfunction, pancreatic hypofunction, easy fatigue, easy to catch a cold, and serious diabetes. The pink of the half-moon mark is a warning before I feel anything unusual.
2. Half-moon sign of index finger-related to gastrointestinal tract
The index finger is closely related to the stomach. When the half-moon mark of the index finger is pink, it shows that the digestion and absorption ability of the stomach and large intestine is poor, and the appetite naturally decreases.
3. The half-moon mark on the middle finger-the spirit of association
The middle finger is related to pericardium meridian. When a person's mental state is unstable, or he is too nervous and tired, he will definitely feel nervous, prone to dizziness, headache, unclear thinking, brain swelling, insomnia and dreaminess. At this time, the middle finger half moon mark will be pink.
4. Endocrine related to ring finger half moon mark
The half-moon mark on the ring finger is pink, indicating that the triple energizer meridian is abnormal in the Ming finger. Abnormal triple energizer meridians indicate imbalance of yin and yang, which may lead to poor blood circulation due to cold or heat, easy physical decline and imbalance of yin and yang. People are prone to unspeakable discomfort, and women may get gynecological diseases such as irregular menstruation.
5. Little finger half moon mark-related to heart and kidney
The half moon mark on the little finger looks particularly pink. Usually, when the blood circulation of the heart is not smooth and the visceral function is abnormal, some conscious symptoms will appear. However, heart disease has no symptoms. Therefore, most patients with heart disease can't know it in the early stage, and it is not discovered until the condition worsens, so people often die suddenly. Therefore, it is very important to observe the heart activity. The best examination is to observe the half-moon marks on the little finger and middle finger.

Nails are a barometer of human health. Normal nails are ruddy, tough, arc-shaped, smooth and shiny, and their roots are gray. If the color of the nail shape changes, it means that the human body may have some kind of disease. Here are some common sense about nails:
From the shape of nails: nails are flat, concave, spoon-shaped, brittle and dull, with signs of liver water deficiency or iron deficiency anemia, hypochromic anemia and light-colored small cell anemia. Nails are parrot-shaped, and fingertips are like drumsticks, which are more common in congenital heart disease with cyanosis, rheumatic heart disease, chronic heart failure and lung abscess, emphysema, silicosis, chronic fibrocavitary tuberculosis, chronic ulcerative colitis and other diseases. The appearance of horizontal stripes on nails is a precursor to nephropathy or myocardial infarction; The appearance of longitudinal stripes is a harbinger of liver disease; The appearance of pit lines is poor respiratory function.
From the color of nails: nails turn white, and hemorrhagic shock is an emergency; Chronic diseases can be seen in anemia, hookworm disease, gastrointestinal bleeding, advanced tuberculosis, pulmonary heart disease and so on. As white as ground glass, it is a characteristic of cirrhosis; Nails turn white, thin and soft, which are more common in chronic wasting diseases. Yellow nails are lack of vitamin E, which is found in hypothyroidism, carrot disease, nephrotic syndrome and so on. Nails turn gray. It's onychomycosis. The nail surface is purple with small red thorns, which is caused by lack of oxygen, indicating that the heart and lungs are sick. Nails are half red and half white, indicating poor kidney function. White spots or flocculent white spots appear on nails, which may be zinc deficiency or gastrointestinal diseases or anemia; Black spots or green spots are signs of poisoning; Erythema appears around nails, which is more common in patients with lupus erythematosus and dermatitis. One and a half months is blue, but the peripheral circulation is poor; Obvious redness is a sign of heart failure; It is obvious for one and a half months, and the intestinal absorption is good; No or narrow, indigestion.
Nail is really a window to observe human health, so we should always pay attention to its changes, especially for long-term manicurists, who forget to take vacations every once in a while and let it show its true colors. If you find multiple nail variations, you should see a doctor in time.
Nail discrimination morphology
edit
Atrophic type: people with this nail shape are too sensitive to nerves and react strongly to various stimuli, and often show malnutrition in clinic.
Hypertrophy: People with this type of nails often feel dull, prone to quadriplegia, easy to catch cold, and have a history of low back and leg pain.
Length: People with long nails are prone to respiratory and cardiovascular diseases, such as tracheitis, pneumonia, tuberculosis and myocarditis.
Short stature: people with short nails are prone to coronary heart disease, diabetes, neurasthenia and other diseases.

Triangle: the nail root is narrow and the head is wide. People with these nails have a history of headaches.
Narrow shape: People with nails of this shape have poor physique, but strong disease resistance and tolerance.
Olive shape: People with this type of nails often suffer from atherosclerotic heart disease, hypertension, cerebral thrombosis, brain tumor and myelopathy.
Fan-shaped: people with this kind of nails are prone to stroke, and it is also common in patients with hepatitis and gallstones.
Concave horizontal line: people with nails of this shape may have parasitic diseases.
Bend and bend: the middle part of the nail is weak, and there are horizontal stripes on the nail. People with this kind of nails often suffer from hookworm disease, indicating that the body is calcium deficient, anemia or malnutrition.
The middle height of the index finger: it looks like a claw nail, which is a sign of tuberculosis.
Semicircle: People with this kind of nails often have renal insufficiency.
Tubular: visible in patients with advanced cancer.
Flat shape: People with nails in this shape are prone to scrofula and throat diseases, such as pharyngitis, laryngitis and acute suppurative tonsillitis.
Vertical lines: There are vertical lines on nails, which are easy to break. Most people with this type of nails have poor heart function or weakened intestinal peristalsis. There are many vertical stripes on the thumb nail, which may be caused by partial eclipse.
Groove shape: There are deep grooves on the nails, indicating that there are many parasites of this shape of nails in the human body, or there is intestinal paralysis. There are grooves in the thumb nails, which often lead to listlessness; Eating nails has grooves, and the skin is prone to rash; There is a groove in the middle nail, suggesting myasthenia gravis; Nameless nails have grooves, which are easy to get eye diseases; Small nails have grooves, which are easy to get hepatobiliary diseases, pharyngitis and neuralgia.
Principles of nail diagnosis
edit
Traditional Chinese medicine believes that claws are not only tendons, but also symptoms outside the liver and gallbladder. The liver stores blood, which governs the drainage. Therefore, Wang Jia can measure the ups and downs of qi and blood and its circulation in the internal organs.
The nail bed under the deck is covered with peripheral capillaries and nerve endings. By observing the morphological changes and blood flow state of capillary in nail bed, we can get the blood circulation of the body. According to modern microcirculation theory, cardiovascular and cerebrovascular diseases can be diagnosed from the changes of tiny blood vessels on nails.
People's nails can reflect information about health or disease. Our ancestors found in long-term in-depth and meticulous observation and repeated verification that the diseases reflected by fingernails of both hands have similarities, differences and certain rules. Generally speaking, thumb nails mostly reflect head and neck lesions; The index finger nail reflects the lesions below the head and above the diaphragm (including upper lesions, chest, heart, lungs, etc.). ); The middle nail reflects the lesions from the diaphragm to the umbilicus (middle jiao, liver, gallbladder, spleen, stomach, etc.). ); Anonymous nail reflects lesions (lower coke, kidney, bladder, intestine, etc.). ) Umbilical to the second yin area; Small nails reflect the lesions below the second yin and lower limbs (second yin, lower limbs, etc. ) nails represent the whole body, and some people call them nail embryos ("holograms"). When shaking hands, the body parts represented by five fingernails add up, just like an embryonic baby.
Besides different nails representing different body parts and organs, people also find that different parts of each nail also reflect the situation of different parts of the human body. Each nail is divided into five areas, representing different parts of the body. Limited to space, I won't elaborate here.
Nail diagnosis method
edit
Candidates should wash their nails, and those with nails should be stained. Under the natural light, make the examinee reach out naturally, palm down and lie flat on the table. Inspectors carefully check the deck, half-moon arc, nail bed, nail fold, etc. And pay attention to the changes of nail color, thickness, unevenness, patches, lines and other shapes.
Deck: Pay attention to its transparency, color, luster, size, thickness, flatness, unevenness, softness, hardness, brittleness, smoothness or rough texture.
Half Moon Arc: Observe its size and color.
Nail bed: press the deck and check the shape, markings, petechiae, color and collateral dynamics of the nail bed through the nail layer.
Nailfold: Pay attention to its shape, color, dynamic collaterals, whether the combination with the deck is regular and whether there are defects.
Nails are pink, shiny, moderate in thickness and hardness, not easy to break and smooth in surface. A healthy circle (half moon at the bottom of the nail) accounts for one-fifth of the length of the nail (preferably all five nails) is a sign of health. If the color is light yellow, cyan, black, dull, too thick or too thin, too soft or too hard, easy to break, rough and dull surface with concave grooves, vertical stripes, white spots and abnormal proportion of healthy circles, it is a sign of poor physical fitness.
Pale fingers indicate deficiency of both qi and blood, and purple indicates blood stasis. Fingers are prone to lithiasis. Spoon refers to the constitution of yin deficiency and yang hyperactivity, which is prone to stroke, chest obstruction, thirst and other diseases. When some hypertensive patients reach out their fingers, their fingers tilt to the thumb side.
Nails should be healthy, mallet nails are incompetent, white nails are deficient in both qi and blood, black nails are serious, and yellow nails are fumigated with damp heat. According to the basic color, it is blood stasis and hands are relaxed, but its color will not accumulate into blood deficiency and qi stagnation for a long time. Patients with leukoplakia often have parasites, fatigue or long-term constipation. Most people with large health circle are hyperactivity of liver yang and stroke; Too young are mostly gout, cough and asthma, gastroenteritis, digestive tract ulcer and encephalomalacia (which can become obscure after stroke); Those who have no healthy circle are mostly deficient in both qi and blood; There are many scars and grooves on the nail surface, which are parasites, spleen deficiency, and if it happens in the thumb, it is exhausted; Skin diseases that occur on the index finger are prone to occur; Most of what happens in the middle finger is flaccid; Those that happen on the ring finger are prone to cough and eye diseases; Those who happen in the little finger are prone to throat diseases, wind arthralgia, damp-heat yellowing.
Too weak nails are yin deficiency and fire flourishing; Thin and soft is liver blood deficiency; Atrophy is mostly due to deficiency of both heart and spleen; The longitudinal stripes are weak; Easy-to-break people are depressed; A flat nail is weak and sickly, and a warped nail is deficient in both qi and blood; Triceratops is prone to stroke; Most people with talons or irregularities are qi stagnation and blood stasis, chest obstruction and wind obstruction, and twinning of tendons and veins; Cylindrical people often have carbuncle and furuncle, which is prone to some kind of tumor; Long claw nails are weak; Nail pits are mostly kidney deficiency. Fan-shaped embedded Donphan is prone to stroke because of liver transverse deficiency, yin deficiency and yang hyperactivity; If the side of the nail drops sharply, it is easy to have heart blood stasis; There is a deep ditch on the nail body, which indicates that he was seriously ill or suffered a mental shock not long ago; Most people who eat nails have a weak temper; Nails are obviously narrow and easy to get dirty and dry; People with long and narrow nails are prone to rheumatism; Most patients with sharp, broad and bluish colors are qi deficiency and blood stasis; People with dull nails and obvious longitudinal stripes mostly cough and gasp; Shortness of nails is mostly due to guilty conscience and chest pain (especially without a healthy circle); Most of them are gynecological diseases and joint pain (if they lack luster, they are mostly infertility); Very short people cough and wheeze easily.
Nail color discrimination
edit
White: the nail bed is pale, suggesting that there is insufficient blood. White moist is mild, white withered is dull and rough, and it is seriously ill. Pale nails are seen in anemia, malnutrition, liver cirrhosis, chronic colitis, nail biting, Raynaud's disease, pulseless disease and so on. Part of leukonychia can be seen in tuberculosis, nephritis, lymphosarcoma and cancer. Spotted white nails (one or several white spots or white clouds or white sheep of different sizes appear on the deck), which are manifested as digestive system diseases, malnutrition, zinc deficiency, syphilis and so on.
Red: the nail bed is red, indicating qi-blood heat syndrome. Those who are ruddy are slightly ill, and those who are red and withered are seriously ill. Bleeding of nail bed also belongs to red nails. If there is spindle-shaped longitudinal linear bleeding on the free edge of the nail, it can be seen in coagulation dysfunction, drug allergy, subacute endocarditis and so on.
Yellow: the color of nail bed is yellow, suggesting damp-heat fumigation. Huang Liang suggested that the illness was mild and the course of disease was short. Dark yellow indicates a serious illness and a long course of disease. Yellow nails can be seen in hepatobiliary diseases, hemolysis, hypothyroidism, chronic adrenal insufficiency, nephrotic syndrome and carotene anemia.
Cyan: blue nail bed, suggesting cold syndrome, blood stasis, pain syndrome and convulsion. Found in hypoxia or using adipine and phenolphthalein. Long-term cyanosis and withering indicate that liver qi will fail and the prognosis is poor.
Black: The nail bed is black, indicating cold syndrome, blood stasis and pain syndrome. After a long illness, black nails appear and wither, suggesting that kidney qi will be exhausted and the disease is dangerous. One or several thin black vertical lines appear on the nail surface, suggesting endocrine disorders, which can be seen in menstrual disorders, dysmenorrhea, malignant tumors, radiation sickness and so on. After receiving radiotherapy and chemotherapy for cancer, each course of treatment can form a black mark on the nail, and each course of treatment has a circle record.
Blue: indicates that the liver is affected by pathogenic factors and blocked by blood stasis. Modern research has found that oral chloroquine, hexadiazepine, hemochromatosis, hepatolenticular degeneration, nitrite poisoning and hypoxia can lead to cyanosis.
Brown nail: common in acanthosis nigricans, adrenal hypofunction, or oral phenolphthalein, antimalarial drugs, etc.
Red and white nail: the distal nail is reddish brown, and the proximal deck is glassy white with clear boundaries, which is common in azotemia of liver cirrhosis.
