NOW Foods White Thyme Oil is a 100% pure essential oil steam-distilled from Thymus vulgaris — the steam-distilled, milder version of thyme oil that has a lower phenol content than red thyme, making it more suitable for aromatherapy use with less risk of skin sensitization. White thyme retains the warm, herbaceous, medicinal aroma of thyme along with its antimicrobial and respiratory-supporting properties, while being less harsh than the phenol-rich red thyme. In aromatherapy, it is energizing and clarifying — supporting mental focus, respiratory comfort, and immune-supportive atmosphere during diffusion. Its antimicrobial activity makes it popular in natural cleaning formulations. NOW Foods tests this oil via GC/MS to verify identity and composition. Dilute well in carrier oil before topical use. Not for internal use.
