Itchy throat and cough with non-stop phlegm are clinically considered as acute pharyngitis caused by upper respiratory tract infection. These diseases are usually viral infections, so you can take oral Chinese medicines with anti-viral effects, such as Pudilan Oral Liquid or Four Seasons Anti-Viral Oral Liquid, and you can also take some cough and phlegm medicines such as Chuanbei Loquat Paste or Licorice Tablets, Lung Power Cough Compound, etc. These medicines can effectively relieve the symptoms of cough and phlegm. If the symptoms do not improve significantly after the above treatment, routine blood and C-reactive protein tests should be completed to see if the blood picture and C-reactive protein are elevated, and if the elevation is clearly combined with bacterial infection, oral anti-inflammatory drugs should also be taken at this time.
