Tongue coating is a term in traditional Chinese medicine, which refers to a thin, white and moist coating on the back of the tongue of a normal person. Because the tongue coating is produced by the stomach qi, and all the internal organs receive qi from the stomach, changes in the tongue coating can reflect the coldness, heat, deficiency or excess of the internal organs, the nature of the pathogenic factors and the depth of the disease. Observation of the tongue coating includes two parts: observing its color and its texture. Coating color: the color of the tongue coating. Pathological coating colors mainly include white coating, yellow coating, and gray-black coating. Sometimes green tongue coating (mostly transformed from white tongue coating, common in epidemic febrile diseases and damp-heat diseases, a sign of damp-heat stagnation) and moldy tongue coating (tongue coating with black and yellow colors in the middle, common in heatstroke caused by overeating or long-term internal heat, and a sign of prolonged damp-heat disease) may also occur.
