Dry and itchy throat and cough are considered to be upper respiratory tract infections due to laryngitis caused by viruses or bacteria from the cold. Anti-inflammatory and anti-viral treatment is very important to relieve the symptoms of dry and itchy throat and cough. In addition, you can also take cough and phlegm medicines, such as cough syrup or lung power cough syrup, or fresh bamboo liquid, which are also effective. If there is pus in the throat or coughing yellow sputum, it means there is a bacterial infection, so you need to take antibiotics at the same time.
