Tongue fire should be adjusted according to the specific situation. If the tongue is painful and red in color, the first thing to consider is whether it is related to the recent consumption of more spicy food, and should stop eating fire-inducing fried food, and change to a light, easy-to-digest diet. If the tip of the tongue is red, accompanied by pain, it should be considered that there is fire in the heart and liver, and medicines that drain the fire and heat from the heart and liver should be given internally, such as Guanchi San or Longdian Diarrhea Liver Pill. If the tongue is red and the moss is yellow and thick, it should be considered that the stomach is on fire, which is often accompanied by the symptoms of grain consumption and hunger, and it is recommended to give the treatment of clearing the fire in the spleen and stomach, and the medicine can be chosen as Huanglian Shangqing Tablets. If the tongue fire is accompanied by intestinal tinnitus and diarrhea, loose stools, burning and other signs of gastrointestinal damp-heat, it is recommended to take Pueraria lobata and Lian Lian Tang to clear the intestinal damp-heat and improve the symptoms.
