Remedies for cough do not have a curative effect. Cough can be seen in a variety of diseases, including infectious diseases (such as bronchitis, pneumonia) and non-infectious diseases (such as gastroesophageal reflux, lung cancer, cardiac insufficiency, etc.). The treatment needs to be tailored to the cause and symptoms of different diseases, and there is no prescription that can directly treat a cough. If the symptoms of cough worsen or long time to cure, or to consult a doctor in time, according to the doctor’s advice to identify the cause to be symptomatic treatment, do not blindly listen to folk remedies.
