Influenza is an infectious acute respiratory disease caused by influenza virus.Although there is no corresponding word “flu” in Chinese medicine,it belongs to the category of generalized typhoid fever.The most common causes are exogenous pathogenic factors such as wind,cold,heat,dampness,dryness and fire,and six exogenous pathogenic factors such as epidemic pathogenic factors.As for different types of influenza infection,there are two types in the pathogenesis of Chinese medicine:typhoid and fever.By observing the patients infected with different pathogenic influenza viruses in Beijing,we found the differences of traditional Chinese medicine (TCM) syndromes after different pathogenic influenza viruses invaded the human body.Therefore,it is necessary to combine disease differentiation with syndrome differentiation in TCM treatment.This paper summarized Professor Liu Qingquan's clinical experience in treating influenza and provides ideas for the prevention and treatment of influenza with traditional Chinese medicine.
