Traditional Chinese medicines as effective agents against influenza virus-induced pneumonia

Influenza virus-induced pneumonia (IVP) is a high morbidity and contagiousness pulmonary infectious disease caused by invasion of the influenza virus into the lower respiratory tract. Currently, the treatment of IVP is mainly based on an anti-influenza virus infection strategy, which includes the use of anti-influenza vaccines and drugs. However, the clinical use of these treatment options is limited as the influenza virus has a high level of variability and drug resistance may occur. Traditional Chinese medicines (TCMs) for the treatment of IVP have unique advantages, a variety of precise curative effects and have been widely used in clinical practice in China both historically and in the present day. However, there are only few literature reviews on the prevention and treatment of IVP using TCMs. Therefore, we conducted a review of relevant literature from the past 10 years and a comprehensive analysis of various databases containing reports on TCMs used for IVP prevention and treatment to provide basic data for future research and development of drugs against IVP. Herein, we summarize research progress on the pathogenesis of IVP, the TCMs effective in prevention or treatment of IVP, their underlying molecular mechanisms and active components. Overall, we provide a theoretical basis for the clinical use of TCM in the prevention and treatment of IVP. Furthermore, we provide a reference for the development of new multi-component, multi-target, low-toxicity drugs, which is of great academic and clinical significance.
