Thick, greasy and slightly yellow tongue coating usually represents the presence of damp-heat, summer-dampness and other pathogens. Jaundice that is characterized by dampness-heat may be characterized by yellowing of the body and eyes, heaviness of the head and sleepiness of the body, fullness of the chest and epigastrium (stomach distension and discomfort), loss of appetite, nausea and vomiting, which may be accompanied by a thick, greasy and slightly yellowish tongue coating. Such patients can be treated by clearing heat and eliminating dampness (removing heat and dampness from the body). Patients who feel heat-dampness may also have a thick, greasy and slightly yellow tongue coating, and may also have high fever, irritable thirst, excessive sweating, short urine, stomach and epigastric fullness, and a heavy body. Such patients need to be treated with methods of eliminating heatstroke and resolving dampness. It should be noted that if the above symptoms occur, it is recommended to seek medical treatment in time to prevent delay. In addition, you should reduce the intake of spicy and greasy food, pay attention to increase exercise and regular rest and relaxation.
