Stress is closely linked by its biological mechanisms to inflammation and by its consequences to accelerated aging. Stress triggers a hormonal response along the hypothalamus-pituitary-adrenal (HPA) axis, which can disrupt the ortho/parasympathetic balance essential for a harmonious life. Proper nutrition, adequate physical activity, and limiting the harmful influence of stress play important roles in avoiding the development of disease and promoting healthy aging. d-Limonene, a monoterpene shown to reduce inflammatory parameters in several pre-clinical and clinical models, could also produce an anti-stress action by altering ortho/parasympathetic parameters as well as central neurotransmitter functions. Here we report on a rat model, where a functional observational battery (FOB) was performed by submitting animals to non-pathological stress. d-Limonene or its metabolite perillyl alcohol (POH) were administered per os at a dose of 10 mg/kg. FOB tests were performed 1 hr before gavage and then at 60, 120, and 180 min. These tests confirmed the stressed status of control rats fed vehicle. Conversely, a series of parameters were significantly less disturbed in treated rats, who retained a better activity and displayed less signs of stress. These effects were more pronounced and sustained after ingestion of d-limonene than POH, suggesting the role of endogeneous metabolization of the terpene. These studies show that d-limonene exerts, through its metabolite POH, a significant anti-stress action measurable by behavioral and physiologic parameters under the influence of the nervous system. In addition to its anti-inflammatory effects, a beneficial role as an anti-stress substance could thus be claimed for d-limonene used as a dietary supplement.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
