## Contribution

The paper provides a comprehensive overview of recent findings on natural products' antiviral effects against swine enteric viruses.

## Key findings

- Natural products show inhibitory effects against major swine enteric viruses like PEDV and PDCoV.
- Traditional Chinese medicine and herbal extracts demonstrate potential as antiviral agents for swine.
- The review highlights new strategies for medicine discovery in the swine industry.

## Abstract

Major swine enteric viruses (SEVs), including porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), transmissible gastroenteritis virus (TGEV), swine acute diarrhea syndrome coronavirus (SADS‐CoV), and porcine rotavirus (PoRV), cause severe gastrointestinal diseases in pigs, leading to huge economic losses to the swine industry around the world. In the absence of specific drugs and vaccines for controlling SEVs in the pig production, this review summarizes the inhibitory effects of natural products against these major porcine enteric viruses. Specifically, it focuses on recent studies regarding the anti‐SEVS activities of traditional Chinese medicine (TCM) compound formulas, herbal extracts, pharmaceutical monomers, and natural metabolites. The review elaborates on how these natural products exert antiviral activities against SEVs, highlighting their potential as alternative or complementary agents for controlling porcine enteric viral infections. Overall, this work provides a comprehensive overview of the research progress in natural products against porcine enteric viruses and demonstrates the new strategies for medicine discovery, which will be helpful for further development of effective antiviral strategies in the swine industry.
