The primary objective of this study was to assess the influences exerted by essential oils derived from thyme (Thymus vulgaris) and oregano (Origanum vulgare) via a comprehensive multi-omics approach within a gnotobiotic murine model featuring colonic microbiotaacquired from patients diagnosed with coronary artery disease (CAD) and type-2 diabetes mellitus(T2DM). Our findings demonstrated prebiotic and potential antioxidant effects elicited by theseessential oils. We observed a substantial increase in the relative abundance of the Lactobacillus genusin the gut microbiota, accompanied by higher levels of short-chain fatty acids and a reduction intrimethylamine N-oxide levels and protein oxidation in the plasma. Moreover, functional enrichmentanalysis of the cardiac tissue proteome unveiled an over-representation of pathways related to mitochondrial function, oxidative stress, and cardiac contraction. These findings provide compelling evidence of the prebiotic and antioxidant actions of thyme- and oregano-derived essential oils, whichextend to cardiac function. These results encourage further investigation into the promising utility ofessential oils derived from herbs commonly used in the Mediterranean diet as potential nutraceuticalinterventions for mitigating chronic diseases linked to CAD and T2DM.
