Preliminary Data on the Senolytic Effects of

Summary: As we age, our immune system accumulates "senescent" cells—often called "zombie cells"—that stop working properly and contribute to aging. Researchers in Japan investigated whether an extract from the plant Agrimonia pilosa (APE), specifically a compound called agrimol, could clear these cells out. They studied 110 middle-aged adults (40–59) who already showed signs of immune aging. For eight weeks, half the group took the supplement and the other half took a placebo.

The results were mixed. When looking at the entire group of men and women combined, the supplement didn't make a significant difference in reducing zombie cells compared to the placebo. However, when the researchers looked at the data for men specifically, they found a reduction in senescent CD8+ T cells (a type of immune warrior). While this suggests the extract might have potential as an anti-aging aid for men, more research is needed to confirm these preliminary findings.
