The theory of traditional Chinese medicine can be divided into actual fire and virtual fire. Real fire means excessive yang. For example, a person always has a bad temper. If he is irritated by something, he will get angry immediately and then curse. His mouth will be dry and even drinking water will not relieve it. In this case, you can take medicine to purge the fire. What you have is a deficiency of fire and a constitution of yin deficiency. It may be caused by staying up late or insufficient Qi and blood due to illness. Just like the water in your body is already low, using cold purgative gunpowder will make the water less and less. The less water will only increase the momentum of fire. So you are still angry. Therefore, you should eat foods that nourish yin, such as pears, white fungus, and lilies. Just eating this is not enough. Find a reliable traditional Chinese medicine doctor and he or she will prescribe some yin-nourishing medicine for you. It will take a long time to adjust the constitution of yin deficiency, so you have to be patient. Then as for daily life rules, don’t stay up late, don’t eat ice cream, don’t eat cold things, including pork in meat, and try not to eat it.
