(Poly)phenolic-rich Mediterranean plants such as Thymbra spicata have been associated with several health-promoting effects. The nutritional value, as well as physiological interaction of T. spicata with the gastrointestinal tract, has not been investigated before. The nutritional composition of T. spicata leaves was here characterized by standard analytical methods. T. spicata leaves were subjected to ethanolic extraction, simulated gastrointestinal digestion, and anaerobic microbial gut fermentation. Phenols/flavonoid contents and radical scavenging activity were assessed by colorimetric methods. The volatile organic compounds (VOCs) were detected by gas chromatography coupled with mass spectrometry. The effect on intestinal integrity was evaluated using a Caco-2 monolayers mounted in a Ussing chamber. T. spicata contains a high amount of fiber (12.3%) and unsaturated fatty acids (76% of total fat). A positive change in VOCs including short-chain fatty acids was observed without significant change in viable microbe. T. spicata and carvacrol (main phenolic compound) enhanced ionic currents in a concentration-dependent manner without compromising the Caco-2 monolayer’s integrity. These effects were partially lost upon simulated digestion and completely abolished after colonic fermentation in line with polyphenols and carvacrol content. Conclusion: T. spicata represents a promising nutrient for the modulation of gut microbiota and the gut barrier. Further studies must better define its mechanisms of action.

Arsenic is a toxic environmental pollutant heavy metal, and one of its critical target tissues in the body is the liver. Carvacrol is a natural phytocompound that stands out with its antioxidant, anti‐inflammatory, and antiapoptotic properties. The current study aims to investigate the protective feature of carvacrol against sodium arsenite‐induced liver toxicity. Thirty‐five Sprague‐Dawley male rats were divided into five groups: Control, Sodium arsenite (SA), CRV, SA + CRV25, and SA + CRV50. Sodium arsenite was administered via oral gavage at a dose of 10 mg/kg for 14 days, and 30 min later, CRV 25 or 50 mg/kg was administered via oral gavage. Oxidative stress, inflammation, apoptosis, autophagy damage pathways parameters, and liver tissue integrity were analyzed using biochemical, molecular, western blot, histological, and immunohistological methods. Carvacrol decreased sodium arsenite‐induced oxidative stress by suppressing malondialdehyde levels and increasing superoxide dismutase, catalase, glutathione peroxidase activities, and glutathione levels. Carvacrol reduced inflammation damage by reducing sodium arsenite‐induced increased levels of NF‐κB and the cytokines (TNF‐α, IL‐1β, IL‐6, RAGE, and NLRP3) it stimulates. Carvacrol also reduced sodium arsenite‐induced autophagic (Beclin‐1, LC3A, and LC3B) and apoptotic (P53, Apaf‐1, Casp‐3, Casp‐6, Casp‐9, and Bax) parameters. Carvacrol preserved sodium arsenite‐induced impaired liver tissue structure. Carvacrol alleviated toxic damage by reducing sodium arsenite‐induced increases in oxidative stress, inflammation, apoptosis, and autophagic damage parameters in rat liver tissues. Carvacrol was also beneficial in preserving liver tissue integrity.

Mercuric chloride (HgCl2) is extremely toxic to both humans and animals. It could be absorbed via ingestion, inhalation, and skin contact. Exposure to HgCl2 can cause severe health effects, including damages to the gastrointestinal, respiratory, and central nervous systems. The purpose of this work was to explore if carvacrol (CRV) could protect rats lungs from damage caused by HgCl2. Intraperitoneal injections of HgCl2 at a dose of 1.23 mg/kg body weight were given either alone or in conjunction with oral CRV administration at doses of 25 and 50 mg/kg body weight for 7 days. The study included biochemical and histological techniques to examine the lung tissue's oxidative stress, apoptosis, inflammation, and autophagy processes. HgCl2‐induced reductions in GSH levels and antioxidant enzymes (SOD, CAT, and GPx) activity were enhanced by CRV co‐administration. Furthermore, MDA levels were lowered by CRV. The inflammatory mediators NF‐κB, IκB, NLRP3, TNF‐α, IL‐1β, IL6, COX‐2, and iNOS were all reduced by CRV. When exposed to HgCl2, the levels of apoptotic Bax, caspase‐3, Apaf1, p53, caspase‐6, and caspase‐9 increased, but the levels of antiapoptotic Bcl‐2 reduced after CRV treatment. CRV decreased levels of Beclin‐1, LC3A, and LC3B, which in turn decreased HgCl2‐induced autophagy damage. After HgCl2 treatment, higher pathological damage was observed in terms of alveolar septal thickening, congestion, edema, and inflammatory cell infiltration compared to the control group while CRV ameliorated these effects. Consequently, by preventing HgCl2‐induced increases in oxidative stress and the corresponding inflammation, autophagy, apoptosis, and disturbance of tissue integrity in lung tissues, CRV might be seen as a useful therapeutic alternative.
