Thyme Oil is water & steam-distilled from the partially dried wild herb, Thymus Vulgaris. Distillation is mainly undertaken in Spain, but also occurs elsewhere in the Mediterranean region. There are many different species of Thyme & within Thymus Vulgaris there are a variety of chemotypes that change the constituent make-up of the oil significantly. The most common chemotypes are " Thymol" & " Carvacrol", which contain high levels of toxic Phenols (up to 60% Thymol & Carvacrol). Absolute Aromas offers " Sweet Thyme", which is sweeter, less toxic & less irritant than the Thymol & Carvacrol types, with a maximum 3% concentration of these components. Try adding 1 drop each of Thyme, Lemon & Rosemary to the water in an oil burner to help create a 'germ-free zone' during times of family ills. Blend 2 drops of Thyme, 3 drops of Geranium & 1 drop of Palmarosa in a teaspoon of Peach Kernel oil. Use a body massage oil to help you get back on your feet after illness or if you are feeling run-down. Do not use Sweet Thyme during pregnancy. Using Thyme in the bath may irritate those with sensitive skin.
