Antiviral effects and mechanism of Qi pi pill against influenza viruses.

ABSTRACT:

Background

Qi pi pill (QPP), which contains Renshen, Baizhu, Fuling, Gancao, Chenpi, Shanyao, Lianzi, Shanzha, Liushenqu, Maiya, and Zexie, was recommended for preventing and treating COVID-19 in Shandong Province (China). However, the mechanism by which QPP treats infectious diseases remains unclear. This study aims to investigate the therapeutic effect of QPP in vitro and on acute influenza infection in mice, exploring its mechanism of action against influenza A virus (IAV).

Methods

The in vitro activity of QPP was assessed using dose-response curve analysis and titer reduction assay, and its antiviral mechanism was identified in vitro by real-time polymerase chain reaction (PCR), time-of-addition, and enzymatic assays. The antiviral efficacy of QPP was further evaluated i
