Apigenin: a natural molecule at the intersection of sleep and aging

Researchers summarized earlier studies of apigenin, a plant chemical found in chamomile, parsley, and celery. The evidence included experiments in cells, animals, and a small amount of human research, rather than one new human trial. Some studies suggest apigenin may affect brain signals involved in sleep and reduce inflammation, an immune reaction linked with many diseases. The research does not show that apigenin helps people live longer or reliably sleep better.

What this means for you: This article is not strong evidence that buying apigenin supplements will improve sleep or slow aging. You can treat the claims as promising but unproven, especially because much of the research was not in humans.
