A generally non-toxic essential oil, the main component in Thyme oil is Thymol, a powerful antiseptic that can be toxic if used improperly and has history of irritating the skin in undiluted use. A small amount should always be tested first for sensitivity or allergic reaction and careful measurement of dosage is required for topical, aromatherapy, and internal uses. Avoid use if you are pregnant or have high blood pressure.
