Abstract:Pneumonia, as a highly prevalent global respiratory disease, generally requires treatment strategies formulated based on its type and severity, including dietary control, moderate exercise, and medication administration. The pathogenic factors of pneumonia are complex, and traditional treatments face challenges of drug resistance. Increasing research indicates that natural products have become a research hotspot in anti-pneumonia studies due to their natural multi-target effects and safety advantages. This article systematically reviews the active anti-pneumonia components in natural products (such as flavonoids, alkaloids, polysaccharides, and organosulfur compounds) and their mechanisms of action, explores their potential applications in pneumonia treatment, and lays a theoretical foundation for the research and development of functional foods with anti-pneumonia properties.
