Our P73 daily use formula is the only, truly unprocessed, full-spectrum wild oregano oil available. The low thymol content in our oil is a sign of quality and a higher safety profile. Oreganol P73 regular strength is 50 mg per serving of total weight. SuperStrength is the same. 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.
