Artemisia annua L. leaf extracts suppress influenza virus infection by targeting the viral nucleoprotein and blocking mitochondria-mediated apoptosis.
Article in Virologica Sinica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Artemisia annua L. is a medicinal herb with multiple therapeutic applications, whereas its anti-influenza A virus (IAV) efficiency and mechanism of action are still unclear. Here, we investigated the inhibition activity and mechanism of A. annua leaf methanol extracts (AALME) against IAV in vitro and in vivo. Our results revealed that AALME exhibits potent anti-IAV activity by interacting with IAV particles. Mechanistically, AALME directly targets the IAV nucleoprotein (NP) protein and abolishes the nuclear import of IAV NP. AALME profoundly suppresses IAV-induced mitochondrial apoptosis via suppressing ROS-mediated AIF-dependent pathways. More importantly, we found that AALME plays a crucial role in protecting mice from IAV infection and mitigating IAV pathogenicity. This current work provides mechanistic insight into the mechanism by which AALME controls IAV infection in vitro and in vivo, potentially contributing to the development of antiviral treatments for IAV infection.
