Answer
60% or higher
The medicinal potency and therapeutic consistency of commercially sourced oregano essential oils depend heavily on the quality of the source material and the rigor of the extraction process. To ensure that an oil provides reliable therapeutic action, quality standards dictate that these oils should ideally be standardized to contain a high percentage of the active constituent, carvacrol. The commonly cited benchmark for ensuring therapeutic consistency in these concentrated oils is a standardization level of 60% carvacrol or greater.
