Oregano oil is extracted from the leaves of the Oregano plant, typically Origanum vulgare. It has a strong, warm, and spicy aroma and is known for its strong antiseptic, anti-inflammatory, and antioxidant properties. It is often used as a natural remedy for respiratory conditions, such as colds and flu, and for skin conditions such as eczema and psoriasis. Oregano oil is also used as a natural preservative in food and as a food flavoring. It is generally considered safe when used topically or internally in small doses, but it should be used with caution as it may cause skin irritation and it is not recommended during pregnancy. Consult a healthcare professional before using it internally or if you have any health concerns.
