CAOH oregano oil: Why USDA Certified Organic? Important: Why is it important that our oregano oil be certified organic? First, it guarantees that you are getting a product free of additives, chemicals, and preservatives. Secondly, buying certified organic oregano oil ensures you get real oregano oil. We have been selling oregano oil since 2004, and since the recent media focus on oregano oil, it has increased in popularity. It has also increased the number of oregano oil products on the market, and many of them are not pure oregano oil or may not even contain oregano oil. Certified organic oregano oil ensures you are buying the real thing at its best! Oregano Oil immediately impacts acute germ infiltration and has been used as a natural, topical antibiotic for centuries. It is safe to use daily or as needed for a fast immune boost. Carvacrol is the active component in Oregano Oil. Our pure organic oregano oil is standardized to a Carvacrol content of 69% without artificial additives, making it the most naturally potent available. Higher amounts would require artificial boosting - thus, claims of natural Carvacrol above 69% are misleading. Quality Control: Produced in a USA FDA-registered laboratory that follows GMP (Good Manufacturing Procedures) and is Certified Organic. Each batch is third-party tested to verify potency and safety.
