Thyme oil is typically acquired from the leaves and flowers of Thymus vulgaris via a steam distillation process. The first distillation produces red thyme essential oil, which is a heady, dark oil with a spicy scent. Red thyme oil is often used as a middle note in perfumery. Thyme oil has antifungal, anti-inflammatory, and antibacterial properties. It's commonly used as a preservative in foods, cosmetics, and toiletries. It can also be found as an ingredient in mouthwash.
