Asthma is an episodic asthma disease caused by phlegm in the lungs, which is triggered by triggers or pathogens, resulting in phlegm blocking the airway, lung failure to descend, and phlegm and qi fighting. During an attack, there is wheezing in the throat, difficulty in breathing, and even inability to lie flat due to wheezing. Asthma is one of the common diseases in internal medicine, which is more common in northern my country. It is generally believed that the incidence of this disease accounts for about 2% of the population. Traditional Chinese medicine has accumulated rich experience in the treatment of this disease, with various methods and significant efficacy. It can not only relieve the symptoms during the attack, but also achieve the purpose of eliminating the root cause and controlling recurrence through strengthening the body. Although there is no name of asthma in the "Inner Canon of Medicine", there are records such as "wheezing" and "enough", which are similar to the characteristics of the attack of this disease. According to the definition and clinical manifestations of this disease, this disease is equivalent to bronchial asthma in Western medicine. Asthma caused by asthmatic bronchitis in Western medicine or other acute pulmonary allergic diseases can refer to the syndrome differentiation and treatment of this disease.
