In Chinese medicine, there are people who look at health from their tongues. What do you think? From the tip of the tongue, both sides, the root of the tongue and the middle, who can help me answer it? How to observe and analyze the tongue picture? You can learn to stick out your tongue. Stick out your tongue naturally, with your tongue flat, the tip of your tongue slightly downward, and your mouth as wide as possible (but not too hard) to fully expose your tongue. If the tongue is stretched too hard, or the tongue is tense and curled, it will affect the blood circulation of the tongue, causing the change of tongue color or the change of tongue dryness and wetness. Look at the tongue in order. Generally, look at the tip of the tongue first, then at the middle and side of the tongue, and finally at the root of the tongue. At the same time, look at the color of the tongue body (tongue substance), the thickness and color of the tongue coating. Observe two key points of tongue diagnosis, mainly observing the changes of tongue body and tongue coating. What color is the tongue? Is the shape fat or thin? Is the texture shiny or dry? Is the activity flexible? Tongue coating-Is the tongue coating thick or thin, wet or dry? Is the moss white, yellow or brown? The characteristics of normal tongue picture Normal tongue picture can be summarized as "red tongue with thin white coating". Specifically, the tongue is reddish and bright, the tongue is moist, the tongue body is moderate in size, soft and elastic, and the tongue coating is even, thin and white. Generally speaking, the tongue coating changes from thin to thick for disease progression, and from thick to thin for disease regression. The common tongue images of patients with gastropathy are: thin white coating-the disease begins at the beginning, the condition is mild, and the stomach gas is not hurt; The tongue coating turns from thin to thick, the color turns from white to a little yellow, the tip of the tongue turns from pale red to red, and there are teeth marks on the tongue-the condition is aggravated, suggesting indigestion, gastrointestinal stagnation, and so on; The tongue coating turns from white to yellow, and the edge of the tongue is red-there is a heat image; The tongue coating turns from yellow to brown, or from brown to black, and it is dry and less fluid, and the tip of the tongue turns dark red-hot, often accompanied by dry stool; The tongue coating is thick and greasy, and there is a layer of white mucus on the tongue surface-phlegm dampness; The tongue coating is thick and greasy, and the tip of the tongue is red and hot; The tip of the tongue is crimson, even purple-blood in the sputum; Red tongue without coating, smooth as a mirror-stomach yin deficiency; Tongue coating peeling, pale tongue-deficiency of both qi and yin. According to the above different tongue images, combined with other diagnostic methods such as smell, questioning and pulse-taking, TCM can make comprehensive analysis and treat according to syndrome differentiation. Abnormal tongue picture that can be nursed back to health by itself, with thick tongue coating and breath. If a person has a thick tongue coating and breath all the year round, it generally means that there is something wrong with the stomach. If there are no other uncomfortable feelings at present, you can start with diet and daily life. Keep a regular life, feel comfortable and happy, eat digestible food, eat more vegetables and fruits, eat less greasy and fried food, and it is best not to drink or smoke. After a period of nursed back to health, abnormal tongue coating and breath are expected to heal themselves. The tongue coating is black and sticky. If you only see this abnormal tongue coating, the tip of the tongue is normal and reddish, and there is no other obvious discomfort, sometimes it belongs to the phenomenon of "staining". The patient may have eaten some colored food or taken some drugs. For example, taking "Julie Dole" will lead to black fur and black stool; When taking antibiotics, sometimes there will be black moss. The above situation is not morbid, so don't be nervous. However, patients with severe stomach diseases should also be vigilant when observing black moss. If the tip of the tongue is crimson or even blue, it means that the condition is getting worse and you should go to the hospital in time. Some people have irregular "map-like" changes in tongue coating, some places are thin and some places are smooth without coating. This is called "map tongue". If people with this tongue picture don't feel any discomfort, it's mostly physiological changes and don't need treatment. If you have stomach trouble or other chronic diseases for a long time, you must have never seen such a tongue picture before. If you have a "map tongue", it is mostly a manifestation of yin deficiency. While treating the primary disease, you can drink American ginseng tea (9 grams per day, brewed with boiling water and frequently drunk) to promote self-healing. People with cracks also have many "cracks" on their tongues, and most of them have no tongue coating, which is called "cracked tongue". If there is no discomfort, it is also physiological and does not need treatment. For example, after a serious illness, there is a cleft tongue, red tongue without coating, and discomfort, which also belongs to yin deficiency and needs medical treatment. Some people with teeth marks on the tongue are fat, and the tongue body is also fat. There are teeth marks on the tongue and the tongue coating is thin and white. If there is no obvious discomfort, it is too fat. According to the theory of traditional Chinese medicine, "Fat people are full of phlegm and dampness", and the spleen and stomach transport function of fat people is relatively insufficient, so the digestion and absorption of food are prone to obstacles. These people should eat less greasy and indigestible food, eat more vegetables and fruits and light food, and exercise properly. If the tongue coating is thick and greasy, there are teeth marks on the edge of the tongue, you don't want to eat, abdominal distension is full, and loose stool is thin, which belongs to excessive phlegm and dampness. You should cooperate with drug treatment and eat light and digestible food at the same time. Some people with red tongue, thick coating and constipation don't understand the stool for a few days. Bad breath, thick coating, red tongue edge and yellow urine belong to stomach fire. The stomach is full of fiery heat, and the turbid gas rushes up and fumigates the mouth and tongue, so bad breath, yellow tongue coating, heat injury to body fluid and intestinal disharmony lead to dry stool. At this time, you can take rhubarb, coptis root, scutellaria root, gardenia and other traditional Chinese medicines for clearing away heat and purging fire. In diet, avoid alcohol and spicy food, such as pepper and mutton, eat more vegetables, fruits and light food, and drink more water.
