Gut microbiome–immune system relationships in older adults and how a traditional botanical was evaluated for potential immune-modulating effects.

Key Takeaways
- Specific gut bacterial taxa were associated with altered circulating immune cell proportions in community-dwelling older adults.
- Polygonatum odoratum treatment modulated immune markers and shifted microbiota composition in experimental assays.
- The study links microbiome variation with immune aging and presents Polygonatum odoratum as a candidate modulator for further testing.
