1, compositional differences: the chemical composition of natural oregano oil is produced by the plant itself, containing a variety of active ingredients, such as eugenol, eugenic acid, geraniol and so on. These components may have a variety of effects on the human body, such as antibacterial, anti-inflammatory, analgesic and so on. Synthetic oregano oil, on the other hand, is manufactured through chemical synthesis methods, and its composition may differ from that of natural oregano oil, and may not fully mimic the complex combination of components in natural oregano oil.

2. Aroma and flavor: Natural oregano oil has a strong aroma and distinctive flavor, and is often used in flavors and fragrances. Synthetic oregano oil may not be able to fully restore the aroma and flavor of natural oregano oil, and there may be some differences.

3. Effect and efficacy: Natural oregano oil may have a wider range of efficacy and effectiveness due to its natural components. It is widely used in traditional medicine, aromatherapy, food flavoring and other fields. Synthetic oregano oil may be able to mimic the effects of natural oregano oil in some ways, but may not be able to fully replicate its natural biological activity.
