Nail diagnosis is a method to diagnose the degree of disease or lesion by observing the blood gas shape and color change of index finger.
Nails are divided into deck and nail bed.
The deck is a horny plate covering the back of the fingertip, with a slightly curved quadrangle, and the length and width are basically the same as those of the fingertip.
The front part of the finger end of deck accessories is called nail bed.
The nail bed and deck are closely connected with each other. The nail bed is rich in capillaries, and the meridians also run through it.
The growth of deck depends on the blood supply of nail bed.
The deck is divided into distal end and nail root, the former is the free front edge of the deck, and the latter is the hidden part of the rear edge of the deck in the depths of the skin. Except for the free distal part, the skin around the other three sides of the deck is warped and raised, which is called nail wall.
The groove between nail wall and nail bed is called nail groove. The inside of the deck is called the spare side and the outside is called the tooth side.
On both sides, between the nail groove and the nail wall, near the nail root, there is a white half-moon area called fox shadow, also called nail half-moon, health circle, safety circle and so on.
The color of fox shadow depends on the thickness of cell layer. When it is old and thick, the capillary network in the nail bed is almost completely impermeable, so it appears white.
The nail bed under the nail root is particularly thick, which is called the nail bottom. Its cells proliferate actively, and the growth of nails depends on the growth of methyl.
No. 1 let's get to know a first.
Normal people's nails are mostly in proportion to the length and width of fingers, generally rectangular, with an aspect ratio of four to three, or slightly square or trapezoidal, pink, which is due to the color formed by the blood vessels in the nail bed passing through the deck. The middle part of the nail is slightly plump, smooth and shiny, moving up and down under strong light, with shiny reflections, spots, lines and silt spots. After releasing the front edge of the deck by hand, the color of nails quickly returned from pale to pink. Normal nails are not easy to break, but they are not too soft, and the deck thickness is uniform. If you carefully observe the surface of the deck, you will find traces of nails growing outward.
People with long nails are gentle and not impatient, so diseases caused by mental factors are rare in them. However, due to their weak innate constitution and poor immune system, acute inflammatory diseases, such as upper respiratory tract infection, gastroenteritis, brain and chest diseases, are prone to occur.
People with short nails belong to a more impatient and impulsive personality. This kind of people's heart function is relatively weak, and they are more prone to diseases from the abdomen to the waist and legs.
If the nail tip is flat and embedded in the meat, it is more prone to diseases such as neuralgia and rheumatism.
The length and width of this nail are connected, that is, they are directly close to a square. These people are in poor health and often don't practice. Although there are no obvious serious diseases, they can easily become patients with many genetic diseases. If women have such nails, they should be alert to problems in the uterus and ovaries.
Nails are long, with obvious protrusions in the middle and curved around, shaped like lily leaves. This kind of nail is more common in women, and the shape of this paper is the most beautiful. However, most people with this kind of nails get sick from childhood, especially the digestive system, and they are more prone to diseases of the blood system.
This kind of nail is narrow under the nail and wide on the nail. Most people with bent fingers and fan-shaped nails are naturally strong. Good organization and strong tolerance, but they tend to ignore their own health, and are more likely to suffer from duodenal ulcer, cholecystitis and even liver disease in adulthood or old age.
The owner of round nails seems to be very strong and seldom gets sick. These people are very insensitive to diseases, and it is difficult to consciously identify the abnormal shape of their bodies, so once they get sick, they are often very heavy. The most likely things to happen to them are ulcers, bleeding, pancreatitis, heart function, dysfunction, and even cancer.
There are protrusions on the smooth nails, and the morphological changes of the protrusions are different, indicating that there are different lesions, but in general, mutation means that there are compensatory lesions such as chronic inflammation and hypertrophy of tissues and organs in the body.
There is a protruding stripe on the nail, indicating that some tissues and organs of the body have chronic inflammation. Chain-like refers to the intermittent mutation on the nail, which looks like a chain, so it is called chain-like change, indicating that an organ has recurrent inflammation.
One or more protrusions on the nail are comma-like, which is called comma-like change. It shows that there is an acute small lesion in a tissue or organ in the body. When the small lesion is cured, another lesion appears, and then it becomes a comma, and one picture after another appears.
There are one or two or three horizontal or arc-shaped protrusions on the nail, which look like waves, which is called lateral mutation, indicating that there are large lesions in the body. With the different nutritional status, treatment and physical rest, the condition will change from time to time and persist.
A healthy nail print needs eight crescent moons at the root of both hands, commonly known as the little sun. From the thumb to the ring finger, the crescent moon is arranged from big to small, and the little finger can be absent. The size of the nail print should be about 2mm from the nail root to the nail edge (the thumb can be 2-3 mm, and the rest will be reduced to about 2mm in turn). The edges of nail prints are neat and clear, and the middle part is full. This kind of nail print is more common in healthy people, indicating that qi and blood are harmonious and the viscera and yin and yang are relatively balanced. Compared with normal nail prints, the increase or decrease of nail print index is not equal to all fingers. , known as abnormal nail prints.
If the crescent moon is rare, even only the thumb has it, and the other four fingers have none, or it is relatively small, which belongs to cold nail prints. This shows that the body is in a state of yang deficiency, and the yang is weak and the yin is cold, which is a manifestation that the yang can not reach the ends of the limbs.
The viscera function of these patients is low, which leads to the invasion or spontaneous generation of cold pathogens. Cold will slow down the movement of qi and blood, causing more diseases such as tumors, lumps or cysts, and fibroids. Some studies have found that 80% of cancer patients, mainly malignant tumor patients, have cold nail marks, indicating that most malignant tumor patients are deficient in cold constitution. Of course, people with deficiency and cold constitution may not all get sick, and people with strong constitution may not all get sick.
-depends on the nature of evil, and secondly depends on the strength of righteousness (that is, the power generated in the body to fight against this evil).
But it needs to be clear that people with deficiency-cold constitution are more likely to get tumors than people with other types of constitutions. Knowing this, people with deficiency-cold constitution can reduce the occurrence of malignant swelling and pain by taking medicine or exercising by themselves, and even if they are sick, they can relieve symptoms, which is very meaningful for nip in the bud and early treatment.
In a large number of clinical cases, cold nail marks account for the majority, almost 70% to 80%. This is also one of the reasons why I attach importance to the important role of Yang in treatment and emphasize "supporting Yang".
If the crescent moon becomes larger or the nail mark index increases, it belongs to hot nail marks. Heat-type fingernail print is a manifestation of exuberant yang and visceral function in the body. The bigger the fingernail prints of normal people. Explain that the better physical fitness (it should also be related to other physical conditions). In the case of disease, it refers to the excess of yang and the relative deficiency of yin, which is empirical, or yin deficiency is due to the excess of yang for a long time, which is a mixture of excess and deficiency. Compared with cold fingernail prints, treatment is more effective.
