The Role of Ginseng as an Anti-Asthmatic Agent

Ginseng is one of the most commonly used herbal medicines in Asia owing to its anti-inflammatory, cognitive, and immune effects. Many of these properties can be attributed to the ginsenosides, major pharmacological agents of ginseng. Ginsenosides influence the innate and humoral immune responses, and previous studies have described ginsenosides as potential therapeutic agents for respiratory disorders. Asthma affects over 300 million people worldwide and is underdiagnosed and undertreated, despite the availability of diagnostic tools and therapies. This review summarizes current studies on ginseng as an anti-asthmatic agent in murine models. PubMed, EMBASE, and Cochrane databases were used to conduct a systematic search of published literature until March 29, 2023. Eight full-text articles that examined the association between ginseng and asthma were reviewed. The findings of this study demonstrate that Korean red ginseng, Korean white ginseng, and ginsenosides exert an anti-asthmatic effect, primarily through reduction in mucus cell hypersecretion, inflammatory cell infiltration, Th2 cytokines, and inhibition of inflammatory NFB and COX2 pathways. We suggest that ginseng has a therapeutic potential for the treatment of asthma. As this analysis utilized murine models, the anti-asthmatic effects of ginseng must be further supported by laboratory studies and clinical trials.
