What is Oregano Oil? Acquired from blending the essential oil of oregano obtained by steam distillation and cold pressing with our natural extra virgin olive oil of high polyphenol value. The carvacrol rate is 80%. Each bottle contains 5-6ml of carvacrol. This oil has Anti-Viral properties. No aroma is used. How should I use it? Since essential oils will lose their properties when exposed to heat, they are more suitable for use before service. We recommend using it for marinating before cooking or as an Olive Oil-based Sauce on raw vegetables, greens and vegetable salads. Ingredients Extra Virgin Olive Oil, Thyme Essence
