Antiviral effects and mechanism of Qi pi pill against influenza viruses.
Article in Animal models and experimental medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundQi 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).
methodsThe 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 in vivo using BALB/c mice infected with IAV. At the same time, each single Chinese herbal medicine in QPP was evaluated to preliminarily identify those with antiviral effects.
resultsIn vitro results showed that QPP exhibited a higher potency antiviral effect against both influenza A and B viruses, inhibiting viral RNA replication and release by targeting RNA-dependent RNA polymerase and neuraminidase. Additionally, QPP significantly decreased the expression of inflammatory cytokines in A549 cells. In vivo study revealed that QPP significantly reduced the lung index and viral load in lung tissue of mice infected with IAV. Renshen, Gancao, Zexie, and Lianzi were the Chinese herbal medicines from QPP that showed anti-IAV activity.
conclusionThe antiviral activity of QPP targets IAV replication and release, cytokine modulation in host cells, and provides protection in mice with acute influenza infection.
