dōTERRA InTune 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.

Depending on whether it is distilled or cold-pressed, one and the same lime yields two oils of very different character. Its scent, sharper and greener than lemon, stands clearly apart. It brings the blend its most direct note.

A herbaceous plant from South-East Asia whose leaves must ferment before distillation, as tea does. This ageing develops its musky, sweet scent, which keeps asserting itself over the years in the bottle. It gives the blend its staying power and its earthy depth.

A low-growing little plant once nicknamed the physician of plants, because it seemed to benefit its neighbours in the garden. Its angelate esters give a fruity aroma, surprisingly close to ripe apple. It softens the whole without weighing it down.

Harvested in sustainably managed Hawaiian forests, this tree needs decades before it can be distilled. Its santalols give a creamy, velvety scent with remarkable staying power. It is what gives the blend its depth and its length.

Its star-shaped yellow flowers, picked by hand early in the morning, have been used in South-East Asian ceremonies for centuries. Rich in benzyl benzoate, its scent is intensely floral, almost heady. It is a signature you recognise the moment the bottle is opened.
