Herbal extract boosts fruit fly lifespan by nearly 25 percent, UCI study finds
Date:6/18/2013

cules in the fly mitochondria and protected both flies and cultured human cells against oxidative stress.

Jafari and Schriner, an assistant project scientist in Jafari's laboratory, are not claiming that Rhodiola supplements will enable humans to live longer, but their discovery is enhancing scientific understanding of how supplements believed to promote longevity actually work in the body.

Rhodiola has already shown possible health benefits in humans, such as decreasing fatigue, anxiety and depression; boosting mood, memory and stamina; and preventing altitude sickness. Grown in cold climates at high elevations, the herb has been used for centuries by Scandinavians and Russians to reduce stress. It's also thought to have antioxidant properties.

Jafari's research group is currently exploring the plant's potential to kill cancer cells, improve Alzheimer's disease and help stem cells grow.

Rhodiola is readily available online and in health food stores. Jafari, though, has analyzed several commercial products and found them to not contain sufficient amounts of the reputed active compounds such as rosavin and salidroside that characterize high-quality products.
