Bronchial asthma is a common respiratory disease, which is clinically divided into exogenous and endogenous. Exogenous asthma usually develops in early childhood and is associated with various allergens such as pollen, dust mites, pet hair, etc. This type of asthma is usually more likely to flare up in the spring and autumn seasons, when allergen concentrations are highest. Endogenous asthma usually begins in adulthood, has a long course of illness, and tends to flare up perennially. This type of asthma is usually associated with lung diseases such as chronic bronchitis and emphysema, and may also be associated with long-term exposure to environmental factors such as irritating gases and smoke. The causes of bronchial asthma are complex, and in addition to allergens and environmental factors, they are also related to individual genetics, immunity and other factors. In addition, seasonal climate changes, respiratory infections, occupational exposure allergies, drug allergies, overwork, and emotional agitation can also trigger asthma attacks. It is important to note that exogenous asthma and endogenous asthma can interact with each other and coexist in the course of the onset. Some patients may have exposure to both allergens and the presence of lung disease. Therefore, in the case of asthma, it is necessary to comprehensively consider the specific situation of the patient and formulate a personalized plan. Because bronchial asthma is often reversed, prolonged and difficult to heal, it is necessary to follow the principle of "the disease is real, the body is weak", "the disease should be treated when it occurs, and the deficiency is treated at ordinary times". That is, the treatment of the disease is emphasized at the time of attack, and the remission period focuses on regulating the body, improving the patient's immunity and resistance, so as to reduce the attack of asthma. 
Its ** principle is:
Adjust your lungs
Asthma is often induced by external evils, so the attack is often accompanied by the loss of the surface of the body, so the clinical ** is mostly used to promote lung scattering products. However, asthma has many roots, and there are many people who are not solid for a long time, and the lung qi is damaged due to the damage caused by the loss of opening and closing, but it cannot achieve the best effect.
Expectoration and turbidity
From the point of view of the onset of asthma, it is the dysfunction of lung qi dispersion and suppression, but the root cause of asthma is still phlegm turbidity. Because phlegm is turbid in the lungs, combined with external sensations, diet, emotion, fatigue and other factors, phlegm obstructs the airway, and the lung qi is reversed, so asthma occurs. And every time this disease has a cough, although the cough is stopped, the cough is always difficult.
Those who see cough and stop coughing do not stop coughing, but the cause of their cough has not been removed, so the ancients had"There is no way to cough".The ring, and the clouds:
"The lungs are like hanging bells, they don't knock or ring, the evil of external sensations will sound when they knock, the phlegm is turbid and the inside is overwhelming, and the upper is against the lungs."
The lungs have an upper mouth, but no lower mouth, and phlegm accumulates in the airways, and with wheezing and breathing, it becomes phlegm. Keeping the airway open is the key to the success or failure of respiratory diseases. Therefore, removing phlegm and turbidity, clearing airway obstructions, and keeping breathing smooth are the main links of asthma.
Desensitized cough
Because there are many mucous membrane allergies such as itching, sneezing, runny nose or cough before the onset of asthma, or there are symptoms of upper respiratory tract infection such as persistent cough and bronchitis, desensitization and cough suppression are also one of the common methods of asthma.
When asthma does not occur, the emphasis is on treating people, that is, when remission, it is mainly to strengthen the kidney, strengthen the spleen and invigorate qi, and it is required to treat the patient according to his age, physique and length of disease.
Pediatric asthma is mostly allergic, and usually eats more, so it is mainly to strengthen the spleen, and often add spleen and antimicrobial products such as prince ginseng, atractylodes, Chuanpu, and tangerine peel on the basis of adjusting lung qi. Middle-aged and elderly people with long-term illness and kidneys, so on the basis of adjusting lung qi, they should be warmed and replenished by the broken paper, dodder seeds, wolfberry, walnut clips, cordyceps, aconite, spirit magnet, etc.
