Asthma is mostly due to congenital deficiencies or recurrent respiratory infections, combined with misdiagnosis and mismanagement, resulting in coughing that does not heal and recurrent attacks, which gradually become persistent over time. When there is a sudden change in climate or other factors stimulate the cough and induce asthma. Western medicine is called allergic asthma, which mainly manifests as extensive bronchial spasm and airway hyperresponsiveness, and is treated mainly with hormone inhalation and bronchial antispasmodic drugs. However, most patients have fear of hormones and cannot adhere to the medication, which often leads to medication failure. Some patients are not diagnosed in time and apply antibiotics for a long time, which is even more harmful. Chinese medicine has a history of several thousand years and has accumulated rich experience in the treatment of asthma, with little toxic side effects, safe medication, long-lasting efficacy, and not easy to relapse. It is believed that the root of the disease is the deficiency of lung, spleen and kidney, and the internal volatile of phlegm and drinks, and that external evil (wind, cold, dryness, odor, pollen, dust, diet, labor, mental stimulation, etc.) is the main factor of asthma attack. Therefore, the key to the treatment of asthma is to avoid the stimulation of external evil and to regulate the functions of lung, spleen and kidney to make them return to normal. Our department has received good results in the treatment of asthma using a combination of Chinese and Western medicine and internal and external treatment. Chinese medicine believes that asthma can be cured, and this was also confirmed by the research of modern medicine in 2009. However, if not actively treated, repeated asthma attacks can also cause structural changes in the airways, which can develop into irreversible emphysema, pulmonary heart disease, heart failure, and straight to respiratory failure. Therefore, if you have asthma, you must go to a regular hospital to get a clear diagnosis and implement the right treatment plan early to avoid structural changes in the airway.
