Californian academics have confirmed golden root (Rhodiola rosea) DOES increase lifespan by 24 percent (well, in fruit flies anyway, and hopefully in humans).
From The Siberian Times: Researchers surmise that the Siberian herb golden root—known in Russia for countering depression, lessening stress, and as an aphrodisiac that works especially well for women—could encourage long life in humans.
“Potentially, humans—healthy or not—could live longer by consuming this root,” said Professor Mahtab Jafari of the department of pharmaceutical sciences at the University of California-Irvine last year. “So far, we’ve only seen the effect in flies, worms, and yeast. But nothing quite like this has been observed before.”
This special herb, which grows in the Arctic and the Altai Mountains, has been lauded in Siberia for centuries, with Russians discovering its strengths from native peoples. Starting in the 1940s, Soviet researchers studied its impact on athletes and later on cosmonauts. It is served as a tea in Siberia and more recently it has been used in “power drinks” and by Clarins in an anti-ageing product.
Professor Jafari stressed: “Although this study does not present clinical evidence that Rhodiola can extend human life, the finding that it does extend the lifespan of a model organism, combined with its known health benefits in humans, make this herb a promising candidate for further anti-aging research.”
The results, Jafari said, “reveal that Rhodiola is worthy of continued study, and we are now investigating why this herb works to increase lifespan.”
Researchers supplemented the diet of adult fruit flies with four herbs known for their anti-aging properties, which were each mixed into a yeast paste. The flies ate this mix for the duration of their lives. Three of the herbs—known by their Chinese names as Lu Duo Wei, Bu Zhong Yi Qi Tang, and San Zhi Pian—were found to have no effect on fruit fly longevity. But Rhodiola was found to “significantly reduce mortality,” reported Biotech Week.
“On average, Rhodiola increased survival 3.5 days in males and 3.2 days in females.” The average lifespan of a fruit fly is about a month to 50 days.
