Patient Wang has cough, sticky phlegm, bitter taste, thirst, red tongue tip and yellow greasy fur.
Natural wind, cold, wind and heat enter the human body through the skin, nose and mouth, which leads to diseases. Wind-heat invades the human body through the nose and mouth. If it enters the lungs and disturbs the respiratory function of the lungs, it can lead to a series of respiratory symptoms. Wind and heat invade the lungs, breathing is not smooth, and cough will occur. Hot air burns the lungs, consumes the body fluid in the lungs, and refines the fluid into phlegm, which may lead to sticky phlegm or yellow phlegm, dry mouth and thirst, and yellow and greasy tongue coating.
The lung is in the upper part of the human body, which controls the breathing movement, and promotes the blood circulation of the human body by absorbing and conveying the natural clear gas to the human body downwards. The liver is in the lower part of the human body, just like the wind wheel of the human body. By pushing the qi and blood in the lower part of the human body upwards, the qi and blood in the lower part of the human body can be handed over to the upper part of the human body. Therefore, the functions of the liver and the lungs are ascending and descending, and complement each other to ensure the smooth circulation of qi and blood in the human body. This patient feels wind-heat, which invades the lung, and the respiratory function of the lung is not smooth, which will naturally affect the coordinated operation of the function between the lung and the liver.
Therefore, the liver will also have problems when it is involved, resulting in bitter taste of disharmony between liver and gallbladder. The disharmony between liver and gallbladder was called "disharmony between shaoyang and the ancients". The ancients said that the typical manifestations of disharmony between shaoyang and the disease were: cold and heat, bitter chest and hypochondrium, silent reluctance to eat, upset and vomiting, bitter mouth, dry throat and dizziness. And "but see a card, you don't have to know everything." That is to say, as long as you see one of the symptoms of "cold and hot exchanges, full chest and hypochondrium, silent desire to eat, upset and vomiting, bitter mouth, dry throat and dizziness", you can conclude that this person is not harmonious with Yang. Patient Wang has a bitter taste, which is one of the typical manifestations of shaoyang disharmony, so it can be judged that this person has committed shaoyang disharmony, that is, disharmony between liver and gallbladder.
Therefore, comprehensively speaking, the pathogenesis of this patient is that the patient feels wind and heat, and wind and heat invade the lungs, while the lungs affect the liver and gallbladder, resulting in disharmony between liver and gallbladder.
Therefore, on the one hand, the wind and heat in the lungs should be driven out of the body, on the other hand, the liver and gallbladder function should be adjusted.
Therefore, Maxing Shigan Decoction was prescribed to clear away heat and spread the lung, so as to get rid of the heat evil in the lung, restore the respiratory function of the lung, and relieve the symptoms of cough, dry mouth, sticky phlegm and yellow greasy tongue coating. At the same time, Huanglian Wendan Decoction is used to regulate the liver, gallbladder, spleen and stomach. The patient's tongue is red and the coating is yellow and greasy, indicating that the phlegm in the body is heavy. Adding Danxing Gualou Fritillaria and Scutellaria baicalensis to enhance the effect of clearing away heat and resolving phlegm, and adding Platycodon grandiflorum and Fructus Aurantii to announce the decline of lung qi and enhance the function of restoring the decline of lung qi. Finally, the patient recovered after taking a pair of medicine.
When the human body feels the evil of wind and heat, wind and heat enter the human body through the skin, nose and mouth, and invade along the respiratory tract. If it invades the throat, it will cause dry throat, itching and cough, and if it invades the lungs, it will cause cough, cough and asthma, phlegm and dry mouth, etc. Different prescriptions will be given according to the different symptoms of patients.
