Background:

  • Diet and gut microbiota significantly influence non-alcoholic steatohepatitis (NASH) progression.
  • High-fat diets (HFDs) induce gut dysbiosis and intestinal barrier dysfunction, leading to liver inflammation via lipopolysaccharides (LPS).
  • Existing NASH therapies have side effects, highlighting the need for alternative hepatoprotective strategies like dietary supplements.

Purpose of the Study:

  • To investigate the efficacy of ginger essential oil (GEO) in preventing NASH.
  • To evaluate GEO's effects on gut microbiota composition and liver inflammation in a murine NASH model.

Main Methods:

  • A murine model of NASH was induced using high-fat diets and LPS injection.
  • The effects of ginger essential oil (GEO) were assessed on liver enzymes, inflammatory markers, antioxidant levels, and gut microbiota.

Main Results:

  • GEO significantly reduced liver damage markers (alanine aminotransferase) and hepatic pro-inflammatory cytokines.
  • GEO increased antioxidant levels (catalase, glutathione reductase, glutathione) and modulated gut microbiota, favoring beneficial bacteria.
  • GEO alleviated hepatic inflammation by inhibiting NLRP3 inflammasome and LPS/TLR4 signaling pathways.

Conclusions:

  • Ginger essential oil (GEO) demonstrates potent NASH-preventive effects.
  • GEO's benefits are linked to gut microbiota modulation and inhibition of the LPS/TLR4/NF-κB pathway.
  • GEO holds promise as a dietary supplement for preventing NASH progression.
