The study aimed to analyze the chemical composition and antimicrobial and antioxidant activities of four oregano essential oils (EOs) from Poland, Europe, Turkey, and the USA. The main component of all tested EOs was carvacrol, with the highest content in the Polish OEO (85.70%). The EOs showed strong antimicrobial resistance, particularly against fungi (MIC = 0.06–0.25 mg/mL), and high antioxidant activity (71.42–80.44%). The antimicrobial activity was influenced by the presence of carvacrol, thymol, and other compounds, with some components showing synergistic effects. The study highlights the potential of OEOs as natural alternatives to antibiotics, especially in the context of increasing antimicrobial resistance. Further research is needed to identify specific fractions and components responsible for their antimicrobial and antioxidant activities.The study aimed to analyze the chemical composition and antimicrobial and antioxidant activities of four oregano essential oils (EOs) from Poland, Europe, Turkey, and the USA.
