This invention discloses the application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against porcine reproductive and respiratory syndrome virus (PRRSV). This invention explores the regulatory effect of *Gynostemma pentaphyllum* polysaccharide on PRRSV replication, and for the first time discovers that *Gynostemma pentaphyllum* polysaccharide can effectively inhibit PRRSV replication in Marc-145 cells. Based on this, this invention proposes a new application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against PRRSV, preferably with a concentration of 12.5 μg / mL to 100 μg / mL. This invention enriches the research on the antiviral activity of *Gynostemma pentaphyllum* polysaccharide and also provides a new technical means for the research and clinical application of anti-PRRSV drugs.
