In the process of disease occurrence and development, the tongue changes rapidly and obviously, just like a mirror of internal organs, which can reflect the occurrence, development and prognosis of the disease. Tongue diagnosis has formed a unique diagnostic method in modern medicine. Observing the tongue to diagnose diseases has the following significance: ① It can judge the functional state of human body. If the tongue is reddish, soft and elastic, and the coating is thin, white and moist, it means that it is healthy and disease-free. ② Determine the location and nature of the disease. If the tongue is normal, the coating is thin and white, and the disease is superficial, it is a mild disease: the tongue is crimson and the coating is thick and Huang Gan, and the disease is deep in the stomach, and the condition is serious. ③ To judge the severity, advance and retreat and prognosis of the disease. It is best to observe the tongue in the sun. The tongue naturally extends out of the mouth, and both sides are flattened to fully expose the tongue body. Observe the changes of tongue quality and tongue coating carefully and test the condition yourself. 1. Tongue color is normal. The tongue is reddish, moist, soft and elastic, and changes when it is sick. With different diseases, the color of the tongue will also change, and the following tongue colors can often be seen. (1) pale white tongue. That is, the color of the tongue is lighter than normal, which is a manifestation of deficiency of qi and blood, indicating that qi and blood cannot be superior to the tongue. Clinically, people with chronic diseases and low physical function are more common, such as anemia, malnutrition and chronic nephritis. There are also many symptoms such as dizziness, fatigue, palpitation and shortness of breath. 2 red tongue. That is, the tongue color is redder than normal, which is caused by fever. It is formed by strong blood flow in the tongue and congestion of blood vessels. If the tongue is red and dry and has a tingling sensation on the tongue surface, it is more common in severe patients with persistent high fever, such as lobar pneumonia, viral pneumonia and Japanese encephalitis. If the tip of the tongue is red, it is more common in patients with insomnia and fatigue; Red tongue edge, more common in hypertension and hyperthyroidism. 3 crimson tongue. That is, crimson tongue, generally evolved from red tongue. The tongue is crimson and dry, with thorns and cracks on the surface, and macula can be seen. The patient was delirious and upset. Crimson tongue is more common in acute severe patients, such as sepsis, encephalitis, abdominal abscess and so on. 4 blue and purple tongue. That is, the tongue is blue, or blue and purple ecchymosis. It is caused by yin injury caused by fever, excessive dehydration and stagnation of blood flow in blood vessels of the tongue. Patients may have symptoms such as listlessness, pallor and cold hands and feet. Violent tongue is more common in critically ill patients with poor prognosis. 2. Observing the shape of the tongue This is a method to diagnose diseases by observing the abnormal changes of the shape of the tongue. Tongue shape is the shape of the tongue, which will change when you are sick. (1) The tongue coating is tender. That is, the tongue is delicate in color, which is common in patients with chronic nephritis and chronic deficiency-cold syndrome. ② The tongue is thick and old. That is, the tongue is rough, hard and dry, which is common in acute fever. 3 thin and thin tongue. It is mainly caused by malnutrition and atrophy of tongue muscle and tongue epithelium, and it is more common in chronic wasting diseases, such as diabetes and cancer. 4 fat tongue. The edema and hypertrophy of tongue body are mainly evidence of deficiency of spleen and kidney yang. Such as chronic colitis, diarrhea and pancreatitis. ⑤ The tip of the tongue stings. That is, the papilla of the tongue is hypertrophic and spiny, which is more common in red tongue, high fever pneumonia and acute fever. 3. Observe the tongue picture ① The tongue is stiff. That is, the tongue is difficult to move, which is more common in coma patients, such as Japanese encephalitis, hepatic coma, cerebral hemorrhage, brain contusion and laceration. ② The tongue is skewed. That is, tongue body deviation, such as cerebral hemorrhage, cerebral infarction, intracranial tumor and so on. 3 tongue weakness. That is, weakness of the tongue is mostly caused by myasthenia gravis and nervous system diseases. 4 tongue wars. In other words, the tongue body can't vibrate spontaneously, which is seen in chronic illness, which is deficiency of both qi and blood and dystrophy of tendons and veins. For example, fever with excessive liver wind is a harbinger of impending convulsion; It can also be seen in hyperthyroidism and severe neurasthenia. 5 the tip of the tongue is exposed. The tongue stretches and relaxes, vomits when it is exposed, closes when it is extended, or licks around the lips, which is common in children with mental retardation and hypothyroidism. ⑥ Tongue shortening. That is, the contraction of the tongue cannot extend out of the mouth, which is common in acute myocardial infarction, hepatic coma, encephalopathy coma and so on. 4. Observe that the tongue coating of people with normal tongue coating is thin and uniform, and the humidity is moderate. When there is a disease, the color and quality of fur will change, which can reflect the severity and location of the disease. 1 moss color. That is, the color of tongue coating, due to different diseases or different periods of diseases, the color of tongue coating changes, that is, from the original thin white coating to white coating, yellow coating, black coating and so on. White fur is more common in upper respiratory tract infections with early onset, mild illness and good prognosis. Yellow fur indicates that there are heat diseases, such as lobar pneumonia, bronchopneumonia, pulmonary heart disease, urinary tract infection and so on. Gray moss and black moss have the same properties, but black moss is more serious than gray moss, which is developed from yellow moss. The patient's body fluid consumption is serious, and at the same time, he may have fever, redness, thirst for cold drinks, yellow stools, delirium and delirium. Black moss can also be seen in advanced diseases such as lung cancer and digestive tract cancer. 2 moss. It is a method to diagnose internal diseases by observing the abnormal changes of tongue coating characteristics. Generally, the following conditions can be seen: thickness. Thin tongue coating means that the tongue coating can be seen vaguely through the surface of the tongue coating, indicating that the onset is early and mild; Thick fur means that you can't see your tongue through the fur surface, which indicates that your condition is serious. If the tongue coating changes from thin to thick. Indicates that the condition has developed; On the contrary, it is a good sign of improvement. Moisten dryness. Moistening means that there is more body fluid lubrication on the surface of the film, indicating that saliva can still be secreted continuously and body fluid still exists; Dry coating refers to dry coating surface and insufficient body fluid, indicating that body fluid is damaged and saliva secretion is damaged. Rotten. Greasy coating refers to fine particles and sticky coating surface, which is more common in constipation, chronic diarrhea, dyspepsia, nephritis and other diseases; Rot moss, that is, the moss particles are large and loose, as thick as rotten residue, which is more common in children's indigestion and intestinal obstruction. Flakiness of flowers means incomplete peeling of tongue coating, which is more common in children with malnutrition and partial eclipse; Tongue coating falls off completely to form mirror tongue, which is more common in disease crisis, such as septicemia, cor pulmonale, gastric cancer and so on. Roots have no roots. Hair root means that the tongue coating is firm and firm, and scraping off is the expression of stomach qi, which can be seen in excess syndrome and heat syndrome; No tongue root coating, tongue coating floating on the tongue, immediately scraped off, is the performance of stomach gas injury, seen in deficiency syndrome and cold syndrome. Tongue coating (2009-05-22 09:56:39) Label: Miscellaneous talk Classification: The tongue coating cured without disease and medicine is thin and clean, evenly distributed on the tongue, moist, moderately moist, not thick or greasy, not slippery or dry. White tongue coating: White tongue coating indicates that there is cold in the body. Whether you eat cold food or catch cold, your tongue coating will turn white. Nowadays, most people have white hair, which is mainly caused by eating too much cold food or gluttony for iced food. Only by eating less cold food and avoiding catching cold can we reduce the influence of cold on the body. If there is less cold in the body, the tongue coating will not turn white obviously. The tongue coating is very white and moist, and it seems that the reflection is enhanced, indicating that the body is not only cold but also wet. This kind of person is prone to edema and phlegm. When the tongue coating is white and excessively wet, you must stop all fruits, stop cold food, never drink iced drinks again, get rid of cold and dampness, and eat more warm food. After the cold and dampness in the body are reduced, the edema is relieved and subsided, and the sputum is obviously reduced. Some people have white tongue coating, but it is dry. This situation shows that this person not only has cold in his body, but also has hot and dry blood in his body. People who encounter this situation should first find out the cause of the cold in his body and eliminate the cause as soon as possible. Second, they shouldn't eat spicy and warm food, such as eating ginger to dispel the cold, which is not appropriate here, because eating these things will aggravate the dryness and heat. So, how can these people get rid of cold and dampness? As long as you don't eat cold food, you won't catch cold. At the same time, we should eat all kinds of foods that are easy to digest, slowly replenish blood and make it moist. If you persist in this way, the tongue coating will not continue to turn white, and the tongue will be moist because of the nourishment of blood. When the tongue is not dry, smoke the whole body with moxa sticks to dispel cold and dredge meridians, and the dry fire will naturally fade. Yellow tongue coating: Yellow tongue coating represents heat in the body, which can be divided into excess heat and deficiency heat. If the tongue coating is yellow and the tongue is red, it means that there is heat in the body, which means that you have eaten too much warm and high-energy food during this time, and the food can not be fully digested and absorbed, which will cause the tongue coating to be yellow. At this time, as long as you eat less high-energy food, eat some radish and hawthorn to help digest and dissolve stasis, eat light food, drink more water and exercise more, the yellow fur will soon fade. If the tongue coating is yellow and the color of the tongue is normal or white, it means that the digestive function in the body is weak and the body is cold, and the high-energy food eaten cannot be transported and absorbed. In this case, you can eat some spicy food to help transport. For example, if you eat hot pot, the yellow clothes will obviously fade away. Thick greasy fur: thick greasy fur is white and yellow. Thick and greasy means poor digestion and absorption ability of gastrointestinal tract, that is, poor gastrointestinal motility and inability to transport food. In view of the thick and greasy tongue coating, you can eat more spicy and warm food, which can raise the temperature and help the spleen and stomach transport; Thick and greasy tongue coating can refer to the method of yellow tongue coating introduced in the above part, and it can be treated according to the quality of tongue. Black tongue coating: What does black tongue coating mean? It shows that the organ function in the body is low, and the dirty and corrupt gas is already very heavy. Most people with this color of tongue coating have poor gastrointestinal function, and foods that cannot be digested and absorbed cannot be excreted at any time and accumulated in the intestines. The toxin after putrefaction diffuses into the body, which is also reflected in the color of the tongue. There are many patients with malignant tumors with black tongue coating in the late stage of the disease, which shows that in the late stage of cancer, the organs are close to corruption and necrosis, and the dirty gas is strong. The color on the tongue clearly records the degree of the patient's illness. Black tongue coating is actually reminding patients that your health is already very dangerous. Patients with terminal cancer and dying can only adjust their bodies slowly and carefully. A dying patient is like a dying fire. Anyone who has used a stove knows that a dying fire can't be turned around. Turn it around and it will probably go out. You can't sprinkle water. Even a small amount of water may put out this weak flame. What should I do at this time? You can only use hay, or smash wood into sawdust, or plane it into shavings, smash coal into pulverized coal, sprinkle it on the fire bit by bit, and then sprinkle these combustible fuels slowly a few times, and the fire will have the strength to burn slowly. When the fire grows stronger, gently poke the stove. At this time, the fire will not be extinguished, but it is more conducive to the combustion of fuel. At this time, with some wood and coal, the fire will burn very brightly. By the same token, we should treat dying patients and patients with advanced cancer with the same caution as dying fire. Fire fighting is the same as treating serious patients. When the patient is extremely weak, many health care methods suitable for normal people cannot be used, such as not exercising, not promoting blood circulation, doing massage as little as possible, and only letting the patient rest quietly; You can't "sprinkle water", that is, you can't eat all kinds of cold and wet foods, including melons and fruits, and you can't cool down from the inside of your body. Then you can mash all kinds of nutritious food and give it to patients. You should also pay attention to your diet. You should feed the patient half a bowl and half a bowl slowly many times. When the energy in the patient's body is slowly and continuously replenished, some massage and a small amount of activities can be properly combined to dredge the meridians. These auxiliary means are more conducive to the digestion, absorption and utilization of food, but when the body grows stronger and stronger, it is not necessary to eat thin, mushy food, but solid food, so that people's physical condition and mental condition will be improved step by step, and many diseases will be alleviated or cured. agree
