How it works

Oregano oil is primarily utilized for its potent antimicrobial and antifungal properties, specifically carvacrol and thymol. While human clinical trials are limited, evidence suggests efficacy in managing Small Intestinal Bacterial Overgrowth (SIBO) and enteric parasites.

Carvacrol and thymol disrupt the structural integrity of bacterial and fungal cell membranes, leading to cell lysis and death.

Safety

  • May cause significant gastrointestinal distress or heartburn if taken on an empty stomach.
  • Long-term daily use may negatively impact beneficial gut microbiota diversity.
  • Avoid use during pregnancy due to potential emmenagogue effects.
