Chinese medicine distinguishes the true and false of internal heat

Traditional Chinese medicine divides "fire" into real fire and false heat. The treatment of real fire is to use purgative methods to clear away heat and detoxify, and to treat false heat is to use tonic methods. How do you know whether you have real fire or false heat? Look at your urine. If the urine is yellow in color and has a strong taste, and your tongue is red, it is real fire; if the urine is light and clear in color, it means your body is cold, and it is false heat. Looking at the bowel movements, if the stools are dry and hard and the tongue is red, it indicates real fire; if the stools are dry and hard, the tongue is pale and the tongue coating is white, it indicates false heat; if the stools are sticky and soft or there is diarrhea, it indicates that the body is cold and it is false heat.
