Can you judge whether you are healthy by looking at your tongue coating?

Hello. Judging the health status of the body by the appearance of tongue coating and inferring the cause are all commonly used methods in clinical practice of traditional Chinese medicine. It is generally believed that the tongue coating is white, thick and dry, indicating that dampness, turbidity and heat damage body fluids. The tongue coating is white, smooth and sticky, which is found in people with phlegm-dampness or dampness trapped in the spleen. Because the average person lacks judgment experience, it is recommended to go to a local medical institution for treatment.
