Lavender essential oil is perhaps the most recognized and widely used oil in all of aroma-therapy -- and for good reason. Its calming effects have been appreciated for generations, while modern research continues to explore how this remarkably gentle oil influences the nervous system, relaxation response and sleep.

Though Lavender is often spoken about casually, the truth is that Lavandula angustifolia is one of the more thoroughly researched essential oils available today. Its effects upon stress, anxiety, restlessness and nervous tension have been investigated repeatedly, helping bridge traditional aromatic use with measurable physiological response.

And interestingly, Lavender appears to work through multiple pathways simultaneously -- aroma, inhalation, skin absorption and direct nervous system influence all seem to contribute to its effects.

Lavender Oil in Traditional Application: Shirodhara

One particularly fascinating study examined Lavender essential oil within the context of an Ayurvedic treatment known as Shirodhara -- a traditional practice involving the steady pouring of warm oil, commonly sesame oil, across the forehead.

Researchers evaluated the effects of adding Lavandula angustifolia essential oil to the treatment oil and found significantly enhanced relaxation responses compared to plain oil alone.

Participants receiving the Lavender-infused preparation demonstrated reductions in reported anxiety levels along with measurable physiological changes involving:

-- heart rate
-- skin temperature
-- psychophysiological state
-- reported relaxation response

Interestingly, the study suggested that Lavender’s effects may arise through several overlapping mechanisms, including olfactory signaling, transdermal absorption and neurological responses associated with sustained sensory stimulation.

This helps illustrate an important point about aroma-therapy: the effects of essential oils are not always limited to simple fragrance perception alone.

The Chemistry Behind Lavender

Much of Lavender’s calming reputation is associated with one of its primary naturally occurring constituents: linalool.

Linalool is found in a number of aromatic plants, though high-quality Lavandula angustifolia oils -- particularly those produced in high-elevation growing regions -- are often especially valued for their balanced aromatic profile and chemistry.

A second study examined inhaled linalool independently from the complete essential oil. Researchers observed measurable sedative effects, including:

-- increased sleep duration
-- reduced locomotor activity
-- lowered body temperature

Interestingly, motor coordination remained largely unaffected, suggesting a calming or sedative effect without the degree of impairment commonly associated with stronger pharmaceutical sedatives.

Findings such as these help explain why Lavender essential oil is so frequently used for relaxation and sleep preparation within aroma-therapy practice.

What This Means in Practice

Lavender essential oil is commonly used for:

-- relaxation and stress support
-- nervous-system balance
-- sleep preparation
-- calming periods of tension or overstimulation

Inhalation remains one of the most effective and traditional methods of use. Diffusion, vaporization and direct aromatic inhalation are all commonly employed depending upon the situation.

A properly functioning nebulizing diffuser, for example, is capable of dispersing sufficient quantities of Lavender oil into the air to create a noticeable aromatic and physiological effect.

And while Lavender is certainly gentle, its effects should not be mistaken for weakness. The oil is remarkably active despite its soft and familiar aroma.

Whole Essential Oil vs. Isolated Compounds

One important distinction should also be made.

While isolated compounds such as linalool clearly demonstrate measurable activity on their own, the complete essential oil represents a far more complex natural material. Lavender oil contains numerous constituents working together simultaneously, contributing not only to its physiological effects, but also to its uniquely soft, balanced and harmonizing aroma.

This synergy between constituents is one of the reasons whole essential oils continue to hold such fascination among both researchers and aromatherapists alike.

Lavender remains one of the true classics of aroma-therapy -- gentle, much-researched and remarkably versatile.

Very nice.
