The root extract of Rhodiola rosea, also known as the golden root, has been widely used in traditional and integrative medical practices in Europe and Asia, where it has been purported to mediate a variety of beneficial effects in humans, such as improved mood, improved physical and mental stamina, and enhanced protection against high altitude sickness [1]. The extract has also been reported to protect against tumor progression in mice, improve endurance in rats, improve blood glucose profiles in diabetic mice, and protect snail eggs against oxidative stress, heat, and heavy metals [2]–[5]. Our group has previously reported that R. rosea can extend the lifespan of the fruit fly, Drosophila melanogaster, protect flies and human cultured cells against oxidative stress, and decrease the production of reactive oxygen species in isolated fly mitochondria [6]–[8]. In addition to the fly, the extract has also been shown to extend lifespan in the worm, Caenorhabditis elegans [9], and in the yeast, Saccharomyces cerevisiae[10]. These observations demonstrate that R. rosea lifespan-extending properties are not limited to the fly, and suggest that it may be a viable treatment to slow aging and abrogate age-related diseases in a range of species, potentially including humans.
