Since autumn, the number of asthma patients has increased significantly. It is especially important for patients and their families to know some knowledge about asthma prevention and control. 1, try to avoid allergen contact: common allergens are pollen, dust, dust mites, pet dander, certain foods such as crab, shrimp, sea fish, mold, certain drugs such as aspirin, certain chemicals such as paint, cosmetics, etc. 2, Quit smoking and avoid passive smoking (such as in the chess room). 3.Exercise properly, avoid getting cold in the morning and evening, and prevent respiratory tract infection. 4.Receive regular treatment. Under the guidance of respiratory specialists and using inhalation and other therapies, asthma has been able to be effectively controlled and asthma patients are able to work, study and live like normal people. Unfortunately, there are still some patients who have doubts about this and would rather believe in mail-order so-called asthma “special medicine” which is illegal and prohibited by the state. In fact, these so-called “pure Chinese medicine” are mixed with hormones and other western medicine ingredients, and the ingredients and dose are difficult to control, and long-term use is extremely harmful. 5. Chinese medicine treats asthma according to the method of identification, with the characteristics of individualized treatment and attention to the remission period. The use of winter “paste” can adjust immunity and prevent attacks, and it is easy to take. The combination of Chinese and Western medicine is more effective in preventing and treating asthma.
