Red is the fire of the spleen and stomach at the root of the tongue, the fire of the heart at the tip of the tongue and the fire of the liver and gallbladder on both sides. Pale white with red, usually accompanied by virtual fire. Tongue redness is common in fever cases and some chronic consumptive diseases, such as epidemic hemorrhagic fever, Japanese encephalitis, septicemia, cholecystitis, bacterial endometritis, heatstroke during fever or fever reduction, and also in the process of long-term consumptive low fever, such as tuberculosis and cancer.
The tongue is uncoated and smooth as a mirror. Mild cases indicate malnutrition or lack of iron or vitamin B2. In severe cases, the body fluid is insufficient and the condition is serious. If the patient's mirror tongue is dark red for a long time, sepsis should be prevented.
If the old man's tongue is as smooth as a mirror and the two veins under his tongue become thicker and longer, it indicates that he has pulmonary heart disease.
There are many red thorns sticking out from the surface of the tongue, just like the fruit of grass mold. Spikes on the tip of the tongue or the edge of the tongue indicate overheating, which can be seen in patients with various febrile infectious diseases or extensive burns.
The tingling of the tip of the tongue is mainly due to excessive heat toxicity or heat entering the blood, which is easy to shock and coma. Insomnia, constipation or night work stress, as well as vitamin deficiency, malnutrition and cerebral cortex dysfunction.
There are scattered purple-black ecchymosis or ecchymosis on the tip of the tongue or the edge of the tongue, indicating that there is "stasis" in the body. For people with blood stasis, the blood flow in the body is relatively slow, and even the blood flow may stop completely in some parts. People bite the edges and tips of their tongues when eating. When a person is sick, the fragility of blood vessels will increase, and sometimes the blood vessels on the tongue will break unconsciously.
Attention should be paid to all the above situations.
