Tongue coating is a TCM term. In the theory of traditional Chinese medicine, because the tongue coating is caused by stomach qi, and the five zang-fu organs are all qi in the stomach, the change of tongue coating can reflect the deficiency of cold and heat in the five zang-fu organs, the nature of pathogenic factors and the depth of the disease. Traditional Chinese medicine also often treats patients through tongue diagnosis.
The common manifestations of tongue coating are white coating, yellow coating, gray coating and black coating.
Generally speaking, the tongue coating of normal people is thin, white and moist;
If the tongue coating is thin, yellow and dry, or the coating is yellow, dry and prickly, it means that the internal heat is abundant and the body fluid is damaged. Thick and greasy tongue coating is mostly caused by phlegm-heat, food retention or damp heat. The tongue coating is yellow and smooth, showing yang deficiency;
If there is gray coating, the tongue coating is thin and slippery, which is mostly caused by cold and dampness. The fur is gray and dry, which is a fever or a fire of yin deficiency.
For black fur, it is mostly transformed from yellow fur or gray fur, and the appearance of black fur often indicates serious illness. Black and dry fur is caused by insufficient heat and body fluid. The tip of the tongue is black and dry, full of heart fire. The coating is black and slippery, and it is extremely rich in yang deficiency and yin cold. In addition to the serious illness, if there is black moss, it may also be caused by excessive use of antibiotics or poor oral hygiene. The decoction of Rhizoma Coptidis 10g can be applied to black moss several times a day. If the black fur becomes shorter and softer, and the color becomes lighter or disappears, it means that the black fur is caused by poor oral hygiene, otherwise we should find out the reason.
Some professionals say that tongue coating refers to a thin layer of dirt covering the surface of the tongue, which is an important content of tongue diagnosis in traditional Chinese medicine. By observing the texture and color of tongue coating, doctors can infer the deficiency and deficiency of patients' viscera function, distinguish the strength of digestive function and reflect the depth and nature of diseases.
Normal people's tongue coating should be thin and white. If there is something wrong with the body, the thickness of the tongue coating will change. For example, the coating of the tongue turns from thin to thick, indicating that the disease is from the outside to the inside, accompanied by symptoms such as indigestion, abdominal distension and nausea. The tongue coating is greasy and rotten, which may be due to phlegm dampness or food accumulation in the body. In addition, the tongue coating becomes thick and greasy, which may also be due to loss of appetite after illness, frequent eating of soft food and liquid, which reduces the mechanical friction effect of the tongue, or because of fever and dehydration, saliva secretion is reduced, and cleaning effect is reduced, which affects the self-cleaning effect of the tongue and accumulates exudates on the tongue surface.
Therefore, once the tongue coating becomes thick and greasy, or the color is black and smelly, you must not scrape off the abnormal tongue coating to save face, but go to the hospital first to prevent it from affecting the doctor's diagnosis.

Of course. If you want to clean the tongue surface in your life, you can use some simple methods, such as brushing the tongue surface lightly with a special soft brush, or gargling with salt water or clear water, but you must not scratch the tongue surface with sharp or hard objects. Don't scrape the surface of the tongue often, because it may damage the nipple of the tongue, cause loss of appetite and be harmful to human health.
Tongue coating is a thin layer of white tongue coating that grows on the surface of tongue. Because the tongue body is red, the healthy tongue coating is white and red, not thick or greasy, not dry or chapped or peeled.
Life Road Public Health believes that tongue diagnosis is one of the characteristics of traditional Chinese medicine, called looking at the tongue, which has a long history.
It is one of the important methods to understand the physiological function and pathological changes of the body by observing the changes of tongue images. Observe the tongue in the order of "tip of tongue-middle of tongue-base of tongue-side of tongue". First look at the tongue body and then look at the tongue coating, about 30 seconds. Generally speaking, it depends on the color and shape of the tongue (old and tender, fat and thin, etc. ), the state of the tongue (tremor and toughness, etc.). ), sublingual collaterals, etc.
If the tongue can't be seen clearly at one time, the patient can rest for 3~5 minutes and then observe.
The sublingual collaterals are short and thin, the peripheral small collaterals are not obvious, and the tongue color is pale, which is mostly caused by insufficient blood and veins. Thick swelling of sublingual collaterals, or blue, crimson, crimson, purple-black, or varicose sublingual collaterals such as purple beaded nodules of different sizes are all signs of blood stasis.
This requires long-term observation and practice, and sometimes the tongue is red and the fur is thin and white at the initial stage of exogenous exterior syndrome and when the internal injury is light and shallow.
The tongue is red, the coating is thin and white, and the tongue is normal.
Thick coating is food accumulation and phlegm-dampness, while little coating without coating is yin injury; White fur is cold and yellow fur is hot; Dry fur is dry and greasy fur is wet.
The most important point: what you see is the result, and the etiology and pathogenesis may be much more complicated, so you need to infer it carefully.
"Who is cold, who is hot and who is cold" belongs to a relatively primary stage.
Thin: the tongue can be seen vaguely through the tongue coating;
H: No, the tongue coating is moist, and the humidity is moderate and normal.
If there is too much water, the tongue will drip into a slippery moss;
Too little water will dry the tongue coating.
Fine white hair is normal;
Pure white is white fur, yellow is yellow fur, and yellow fur can be divided into light yellow, dark yellow and brown according to different colors.
Tongue coating turns from white to yellow, or yellow and white alternate with each other, mostly due to exogenous pathogens entering the interior, both in the exterior and the interior.
As long as people are healthy, the tongue coating is naturally healthy. It is not tongue coating that determines health, but physical health that determines the color of tongue coating. If you don't like the color of tongue coating, ask a doctor.
