Clove (Syzygium aromaticum) is a popular medicinal plant which has been traditionally used in India as spice and medicine to counter various ailments. However, the stress modulatory and antiaging potential of this plant is yet to be characterized. Therefore, the present study evaluates the effect of clove oil (CO) on oxidative stress, lifespan, mobility, and the expression of aging-related proteins using Caenorhabditis elegans model system. The CO (10 ppm) was found to extend mean lifespan in worms by 21.4% (p < 0.001) under normal and by 63% (p < 0.0001) under juglone-induced oxidative stress conditions. The extension of mean lifespan in mev-1 mutant and elevated expression of gst-4 and sod-3 confirmed stress modulatory effects of CO. Additionally, the CO reduced intracellular ROS and Aβ₁–₄₂ proteotoxicity. Altogether, the present study unravels the anti-aging and stress modulatory potential of CO and suggests CO as a potential pharmaceutical entity in modulating aging process.
