North American Herb & Spice was the first company to introduce edible oil of oregano to the North American market which led to the health improvement of countless numbers of people. It is handpicked in pristine, and unpolluted remote mountains. There is no substitute for Super Strength Oreganol P73, the original, truly wild, organic, oregano oil that is produced by old-fashioned steam distillation. Our P73 daily use formula is the only, truly unprocessed, full-spectrum wild oregano oil available. As a natural product our carvacrol levels vary from 65% to 84% while our blended oregano species creates a synergistic balance of over 30 phytochemicals. The low thymol content in our oil is a sign of quality and a higher safety profile. However, the difference between super strength and regular strength is that the ratio of olive oil to oregano oil is considerably different, by nearly 3-fold. Because it is so potent you can benefit from every-other-day use.
