Ginsenosides and gut microbiota: differential effects on healthy individuals and irritable bowel syndrome subtypes.

BACKGROUND

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder with poorly understood mechanisms. Variations in gut microbiota composition are observed in different IBS subtypes. Ginsenosides have shown potential in alleviating IBS symptoms, but their interactions with gut microbiota in different IBS subtypes are not well studied.

METHODS

In this study, we investigated the effects of ginsenosides on the gut microbiota of both healthy participants and participants suffering from IBS characterized by diarrhea (IBS-D) or constipation (IBS-C), using fermentation alongside 16S rRNA sequencing and bioinformatics analyses.

RESULTS

The analysis demonstrated that there were no statistically significant alterations in α- or β-diversity between the ginsenosides-treated and control groups across all models. However, the microbial composition assessment revealed the presence of 51 shared genera, with notable variations in composition and a significant enrichment of specific taxa. Specifically, the LEfSe analysis revealed that, following ginsenosides treatment, the healthy model groups exhibited significant enrichment of and , while the IBS-D model groups demonstrated significant enrichment of and .

CONCLUSIONS

The results elucidate the distinctive microbial signatures associated with ginsenosides treatment across both healthy and IBS-D groups, underscoring the potential therapeutic efficacy of ginsenosides in modulating gut microbiota. This study highlights the necessity for further investigation into targeted microbiome therapies for IBS, which may facilitate the development of more personalized and efficacious treatment strategies for gastrointestinal health.
