dōTERRA PastTense Roll-On Blend | 10 ml

Often called the king of essential oils. It is obtained by scoring the bark of trees grown in semi-desert country, then distilling the dried resin that beads from the cut. Its scent combines woody, resinous and faintly citrus notes. Used in ancient Egypt for perfumes and balms, it gives the blend its depth.

The best-known oil in the world, and probably the oldest: the Romans already scented their baths with it, which is where its name comes from. Its linalool and linalyl acetate form that soft floral aroma, recognisable at once. It is the heart of every blend it enters.

A natural hybrid of water mint and spearmint, peppermint is grown for its high menthol and menthone content. Menthol is what produces the immediate sensation of freshness, whether the oil is diffused or applied to the skin.

A Mediterranean shrub with needle-like leaves, held sacred by the Greeks, the Romans and the Egyptians. Its 1,8-cineole and camphor give a bright, herbaceous scent, almost resinous. It cuts through the sweetness of the spices and keeps the blend from turning into a dessert.

This is not an essential oil but a carrier oil. It is called fractionated because the longest fatty acids have been removed, which keeps it permanently liquid and odourless. It is what makes it possible to apply the blend directly to the skin, with no stain and no greasy feel.
