The Active Ingredient Is: Oregano Oil (Origanum vulgare) Extract

Oregano oil extract is a rich essential oil extracted from Origanum vulgare and is paired with a carrier oil, usually olive oil. This preparation provides an intensified herbal component that is commonly used within dietary supplements for its bioactive constituents.

This mixture focuses on oregano oil extract as the main ingredient, with the olive oil carrier aiding stability and delivery. It is designed for inclusion as a nutrient-packed botanical extract in a supplement context.

What Does Oregano Oil Do?

Oregano oil acts as an antioxidant and contributes to broad-spectrum antimicrobial activity, supporting normal digestive tract function and overall digestive health. Scientific understanding suggests these mechanisms may help in maintaining a balanced microbial environment in the gut.

Dr. Marchese of the University of Bari found that oregano oil constituents like carvacrol and thymol contribute to antioxidant effects and antimicrobial properties, underpinning oregano oil's traditional use in supporting gastrointestinal health.
