Herb oil is a concentrated liquid extracted from various plants, often used for culinary, medicinal, or aromatic purposes. These oils are typically made by infusing carrier oils, like olive or coconut oil, with herbs such as basil, rosemary, or thyme. The process captures the essential flavors and properties of the herbs, making them versatile for cooking or natural remedies. In addition to culinary uses, herb oils can also be utilized in aromatherapy and skincare. They may provide therapeutic benefits, such as relaxation or improved mood, when used in diffusers or massage oils. Popular examples include peppermint oil and lavender oil, known for their soothing effects.
