The Impact of Rosemary and Ginger Extracts on Aging and Healthspan in Drosophila.
Article in Aging and disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aging leads to a decline in physiological functions and increased risk of mortality, yet therapeutic avenues are limited. Dietary phytochemicals provide an attractive approach to counteract age-related health decline. Here, we have examined the impact of feeding extracts of rosemary and ginger, prepared via three different extraction methods, on markers of aging and healthspan in the fruit fly Drosophila. We observed that certain, but not all, extracts of ginger produce modest prolongevity effects. Feeding extracts of rosemary, produced via the three different methods, each produced prolongevity effects. We observe that feeding combinations of both rosemary and ginger extracts leads to robust lifespan extension. We find that the prolongevity effects of rosemary and ginger extracts are linked to improved intestinal barrier function in aged flies. Importantly, we show that the anti-aging effects observed are not linked to reduced food intake. Interestingly, we observe several instances where the combination of rosemary plus ginger produces effects which are more pronounced or not seen for either extract alone. In terms of cellular hallmarks of aging, rosemary plus ginger feeding leads to AMPK activation and improved markers of autophagy and proteostasis in aged flies. Furthermore, feeding the combination of rosemary plus ginger feeding improves cognitive function in aged flies. Our results demonstrate that rosemary and ginger extracts can counteract aging and prolong healthspan in flies.
