This is the true wild oregano oil P73, a blend of edible species of wild oregano grown on natural mineral rich soils. This growing condition along with our dedication to a 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 of the P73, it is truly one of a kind. Oreganol P73 can be used either internally or topically. Safe for everyday use.
