Skin Repair Properties of d-Limonene and Perillyl Alcohol in Murine Models
The orange-peel derived terpene d-Limonene, probably through its metabolite, perillyl alcohol (POH), has been reported to have tissue-repair properties. Two murine models of respectively 12-O-Tetradecanoylphorbol-13-Acetate (TPA)-induced dermatitis and mechanical skin lesion were used here to assess the efficacy of d-Limonene or POH applied topically. Macroscopic and microscopic evaluation of skin lesions was performed as well as that of P-selectin expression, together with measurements of serum concentrations of IL-1β, IL-6 and TNF-αin the first model.

Anti-stress effects of d-Limonene and its metabolite perillyl alcohol
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, liable to disrupt the ortho / parasympathetic balance essential for a harmonious life. Proper nutrition and adequate physical activity, by limiting the harmful influence of stress, play important roles to avoid developing disease and to promote healthy aging. d-Limonene, a monoterpene shown to reduce inflammatory parameters in several pre-clinical and clinical models, could
