Slowing aging is a widely shared goal. Plant-derived polyphenols, which are found in commonly consumed food plants such
as tea, cocoa, blueberry and grape, have been proposed to have many health benefits, including slowing aging. In-vivo studies have demonstrated
the lifespan-extending ability of six polyphenol-containing plants. These include five widely consumed foods (tea, blueberry,
cocoa, apple, pomegranate) and a flower commonly used as a folk medicine (betony). These and multiple other plant polyphenols have
been shown to have beneficial effects on aging-associated changes across a variety of organisms from worm and fly to rodent and human.
