asthma
Asthma is a bronchial hypersensitive disorder characterized by reversible airway obstruction caused by a combination of mucosal edema, constriction of the bronchial musculature and excessive secretion of viscid mucus. In asthma, there is a continuous state of hyperreactivity of the bronchi, during which exposure to a wide variety of bronchial irritants will precipitate an asthmatic attack. In normal subjects, inhalation of histamine or carbachol may cause a little increase in airway resistance. By contrast, the bronchi of the patients with asthma are highly reactive and show marked bronchoconstriction in response to these substances. This phenomenon is termed bronchial hyperreactivity. I suggest that you should consult to expert for health advice. A TCM service platform for public health which may help to solve your problems is recommended to you.
