About this item

  • WILDCRAFTED MEDITERRANEAN OREGANO: Steam-distilled from wild oregano (Origanum vulgare) harvested in unspoiled Mediterranean mountain regions, standardized to 75% carvacrol - the compound most closely tied to oregano oil's antioxidant activity.
  • 8.33MG OF STANDARDIZED CARVACROL PER DROP: Every drop delivers a consistent, lab-verified 75% carvacrol standardization (8.33mg) - a way to know exactly how potent each dose is, unlike unstandardized oregano oils.
  • SUSPENDED IN AN MCT OIL BASE: This formula uses medium chain triglycerides (from coconut) rather than olive oil, which is more prone to oxidizing from light and heat exposure.
  • AN ANTIOXIDANT SOURCE: Oil of Oregano is a source of antioxidants, helping to counter everyday oxidative stress as part of a balanced wellness routine.
  • PRECISE DROPPER DOSING: Each 15ml bottle delivers approximately 450 drops, providing roughly a 112-day supply at the 4-drop adult dose - dispensed with an easy-to-use glass dropper.
