If a person has a dry and sore throat, red eyes, hot nasal cavity, dry mouth, sore tongue, rotten mouth, nosebleed, toothache, etc., Chinese medicine considers it as “fire”. How does “fire” arise? First, the human body is directly attacked by the natural “fire and heat of the evil” and cause “fire” symptoms; second is the existence of the invisible “fire” in the human body to promote life activities, that is, due to the imbalance of Yin and Yang The second is the presence of the invisible “fire” in the body that drives life activities, i.e., the symptoms of “fire” due to the imbalance of Yin and Yang. There are many specific factors that can cause “fire”. For example, excessive mood swings, cold, wind, addiction to alcohol and tobacco, as well as excessive consumption of spicy products such as onions, ginger, garlic, chili peppers, greed for fatty products such as mutton and dog meat, and lack of sleep can be “on fire”. In Chinese medicine, symptoms in the upper part of the body, such as dizziness and sore throat, are called “upper jiao fire”; symptoms in the middle part of the body, such as irritability and thirst and stomach pain, are called “middle jiao fire”; and symptoms in the lower part of the body, such as constipation and red urine, are called “lower jiao fire The symptoms in the lower part of the body, such as constipation and red urine, are called “lower jiao fire. In addition, according to the opening of the internal organs, the redness and swelling of the eyes are called “liver fire”, nasal fan and asthma are called “lung fire”, mouth and tongue sores are called “heart fire” and so on. Combined with the internal situation, these fires can also be divided into two categories of “virtual and real”. Those with heavy symptoms and fierce onset are real fires; those with mild symptoms and long duration with fever in the hands and feet, hot flashes and night sweats are deficiency fires. This classification is to provide the basis for treatment with medicine. To treat “fire”, we should pay attention to the Chinese medicine theory of evidence-based treatment. For example, for the treatment of “middle-jiao fire”, it is advisable to use Qingzhi San, for the treatment of “heart fire”, and for the treatment of “real fire”, it is advisable to use Sanhuang tablets, Niuhuang detoxification tablets, etc. to release the fire. Therefore, patients should not use their own medicine to treat “fire”, if you do not know how to identify the Chinese medicine, see the “fire” on the use of three yellow tablets and so on, sometimes it does not work, but misunderstood. Experts suggest that the treatment of “fire” is best carried out under the guidance of an herbalist.
