For asthma, generally speaking, western medicine mainly uses inhaled sex hormones, such as budesonide and seretide. This medicine actually has certain effects, such as quick response. However, the more serious the dose is, the longer the hormone is used, the more dependent the human body will be. For example, after a month or a period of time, your condition is under control and someone will stop taking hormones, so maybe a few days later, there will be strong side effects. However, if inhaled sex hormones are used for a long time according to the doctor's dose, the danger should still be controllable. Traditional Chinese medicine has some effective drugs for asthma, such as buckwheat tablets, which are more effective for asthma, but the effect is slow, usually taking about a week. But if you don't take the medicine for a long time, there are no side effects, and it is a plant, which may hurt the spleen and stomach for a long time. In addition, some folk remedies are also effective for asthma, for your reference: 1, kill a black-bone chicken, wash it, and ginger. Avoid spicy food, leeks and mutton. 2. Dry cough (caused by cold or allergy): raw black sesame 3 yuan (about half a tablespoon), and mashed rock sugar. Make half a bowl of soup with boiling water, take it on an empty stomach in the morning and recover in 3 days. Avoid eating fish and salty food. 3. Cough with phlegm (including acute bronchitis, bronchitis and tracheitis in children): Use two or two white radishes and two or two pears each time, chop them up together, add a bowl of water to cook them, and put a proper amount of crystal sugar to eat them twice a day for three days to relieve cough and eliminate phlegm. Avoid eating fish. Finally, I suggest you go to the hospital to check your allergens. Cough variant asthma is allergic cough. You've been in poor health for a long time, and you probably haven't removed your allergens. You'd better check whether it is allergic rhinitis. If it is allergic rhinitis, there are many remedies that can be cured and are harmless to people. If it is other allergens, as long as you leave the allergens, you will naturally not make the mistake of looking at your situation again today. Add some points: 1. Variant cough is allergic cough. You should be clear about this. Hospitals can check allergens, but there are still many allergens that can't be found. You can write a life diary for a period of time, record in detail what you eat, use and touch every day, and look for allergens. This record should be adhered to. 2, try different environments, some people are allergic in wet areas, just like in dry areas, and so on. If you can change the environment for a few days, you should also record whether there is any difference. 3, check whether there is allergic rhinitis, many variant coughs are caused by allergic rhinitis. You said you cough when you lie down, and it's worse when it rains. It may be that mites are allergic to mold. Bedding should be washed with hot water above 50 degrees, and then exposed to the sun. The room should be airy and dry. It is recommended to pay attention to what your cough looks like when it is dry and ventilated outdoors and humid and fresh indoor air. Judging from your current situation, I can only analyze so much. If you have any further information, I can consider it.
