The symptoms of stomach fire can be divided into three categories: 1. Gastrointestinal symptoms are mainly related to relieving hunger, namely, hunger, large appetite, difficulty in digestion, constipation, red tongue and thick coating. 2. If the stomach fire is upward, there will be breath, swollen gums, acid regurgitation, heartburn, etc. 3. When the stomach fire goes down, there will be yellow and red urine, burning sensation in the anus, more exhaust, etc. When there is a big stomach fire, we should pay equal attention to treatment and recuperation, and we can use drugs to clear stomach fire. Conditioning is more important. For example, drinking more water, eating a light diet, not eating fat and sweet food, living a regular life, not overeating, reducing staying up late, and maintaining emotional stability will be good for reducing stomach fire. It is best not to do this through recuperation, but when it happens, you can take Chinese medicine to clear heat, detoxify and lower the heat at the same time.
