Oregano oil is an essential oil derived from the leaves of the oregano plant, known scientifically as Origanum vulgare. It is commonly used for its potential health benefits, including its antibacterial and antifungal properties. The oil is rich in compounds like carvacrol and thymol, which are believed to contribute to its effectiveness against various pathogens. In addition to its medicinal uses, oregano oil is often used in cooking to enhance flavor. It can be found in various forms, including capsules, liquid extracts, and as a topical application. However, it is important to use it with caution, as it can be potent and may cause irritation if applied directly to the skin.
