When the weather gets cold, I have a cough and phlegm. What’s going on?

I think we need to understand why we cough first. For example, someone smoking at home or a pungent smell can cause coughing. This kind of short-term stimulation caused by the outside world, coughing is a defensive response of the human body, and its function is to expel foreign matter, and generally does not require treatment. Continuous coughing will cause strong irritation to the throat, causing the secretory glands in the throat to increase secretion and produce sputum, which will eventually fall into wet cough. If you suffer from phlegm cough, you need to rely on some antitussive and expectorant drugs for relief and treatment. For example, Mushu Tudan Oral Liquid can dissolve and thin phlegm and promote the discharge of phlegm, which can expel the dirt accumulated in the airway. .
