We often refer to asthma as bronchial asthma, which, whether it is cough variant asthma, allergic asthma, or caused by other factors, has not yet a cure found to date. It is now generally believed that bronchial asthma can be controlled, which means that as long as patients with bronchial asthma receive standardized treatment in reputable hospitals, most can be controlled and will not suffer from recurrent attacks. So far, there is no cure found, and all advertisements using Traditional Chinese Medicine or ancient secret remedies or any other means claiming that asthma can be cured are false. These are not to be trusted, and many asthma patients often suffer because they take some medications containing oral corticosteroids under these false beliefs. While these might control asthma in the short term, they are detrimental to the long-term management of asthma, and prolonged use of such non-standard corticosteroid treatments can lead to many adverse reactions, such as drug-induced Cushing's syndrome and medication-induced diabetes, among others.
