Oreganol P73 is the true wild oregano oil P73, a blend of edible species of wild oregano grown on natural, mineral-rich soil. This growing condition, along with our dedication to chemical-and-alcohol free extraction, is the reason P73 Oreganol oil has a unique chemical profile, which is ideal for human consumption. This same oregano species can be grown elsewhere and not have the same effect as the P73; it is truly one of a kind. Oreganol P73 can be used either internally or topically. Safe for everyday use.
