Our Oil of Wild Oregano is not standardized and never will be! Standardization includes the adulteration and/or the alteration of a product. To standardize Oregano Oil, a constituent must be added or taken away, and this does not benefit the consumer as the 3 main chemical constituents work synergistically together to provide the therapeutic qualities of Oil of Wild Oregano, not on their own. Many studies have shown that the main chemical constituent; Carvacrol, a great antibiotic, does not work on its own. Tests have shown that pure Carvacrol is not as effective as pure Oil of Wild Oregano4. Whether it is increasing the Carvacrol by fractioning the essential oil after distillation by boiling off other natural components to increase the Carvacrol content; or adding Carvacrol to the water during distillation or afterwards; or even removing whole parts of the plant's makeup, it puts the natural synergy of the active constituents out of balance. We would rather give you what nature provided, that has naturally high Carvacrol vs. the highly over claimed products on the market.
