North American Herb & Spice Super Strength Oreganol Caps is the triple strength oregano in an easy to take softgel. P73 is 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. The same oregano species can be grown elsewhere and would not have the same effect of the P73, it is truly one of a kind. Super Strength gelcaps are ideal for those who take the oil internally.
