The Study
Effects of flavonoids on senescence-associated secretory phenotype formation from bleomycin-induced senescence in BJ fibroblasts.
This study tested if certain plant chemicals called flavonoids can calm down angry aging cells in a dish and in rats. It found they might help, but it didn't test this in people. So we can't say these chemicals will help humans feel better.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
As cells age, they leak inflammatory chemicals that harm nearby tissues. This study tested if natural plant chemicals can stop this leak without killing the cells.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — reducing these inflammatory signals could help slow age-related diseases like arthritis or kidney damage.
- 2Apigenin (a plant chemical) reduced inflammatory signals like IL-6 by over 50% in aging human cells and in aged rat kidneys.
- 3Only apigenin and kaempferol worked among 66 tested compounds.

Of 66 natural compounds tested, only apigenin reduced the gene expression pattern linked to cellular aging without killing the aged cells.
Apigenin reduces the release of inflammatory signaling molecules IL-6, IL-8, and CXCL10 from aged, non-dividing cells.
When aged rats are given apigenin by mouth, the levels of specific inflammatory messenger molecules in their kidneys decrease.
Apigenin and kaempferol reduce the inflammatory signals released by aged human skin cells without stopping the cells from being aged.
Flavonoids with hydroxyl groups at specific positions on their molecular structure directly inhibit the production of SASP, a set of molecules linked to cellular aging.
Apigenin and kaempferol decrease the production of inflammatory proteins IL-6, IL-8, IL-1β, and MMP-3 in aged human skin cells by inhibiting NF-κB p65 and IκBζ.
