Our wildgrown Oregano oil is 70.66% Carvacrol. Please do note, it’s not just about carvacrol! One could get carvacrol on its own, and it would not be as effective. It is the combination of all constituents in an essential oil which makes it do what it does. EVERY scientific study comparing what scientists think is the ‘active’ ingredient in an essential oil, comparing it to the whole oil itself for the given application (ie. antimicrobial) shows the whole oil to be more effective.
