The science of scent and memory: Sandalwood as frequency

Have you ever caught a scent in passing and instantly been taken somewhere else?

A place. A person. A feeling.

You notice it in your body first. Your breath shifts. Your heart rate changes. Something activates before you understand why.

This happens because scent goes directly to the limbic system, the part of the brain that processes emotion and memory.

First the body responds.
Then the mind catches up.

At NEH, we often refer to this as frequency.

Everything carries it: people, places, environments, and scents.

And when you become aware of it, you begin to notice how different inputs influence how you feel, think, and move through life.

Scent becomes more than something you wear. It becomes something you experience.

A way to access your inner state and, from there, influence how you move through your outer world.

Sandalwood as frequency

Research suggests that the sandalwood aroma may be associated with a calmer nervous system and increased parasympathetic activity, the state linked to rest, recovery, and regulation.

Because of this, sandalwood has historically been used in traditional medicine and aromatherapy to support individuals experiencing overstimulation, restlessness, and difficulty settling.

Not as a treatment, but as a sensory input that supports the body's natural ability to down-regulate.

Just like rose, the aromatic compounds bind to receptors in the nose and activate the olfactory system, which sends signals directly to the limbic system, the brain region responsible for emotion, memory, and instinctive response.

This pathway helps explain why scent can influence internal states before conscious awareness catches up.

With sandalwood, the effect is not emotional activation, but a reduction in internal activity.

Less urgency. Less mental movement. Less reactivity.

Breathing naturally becomes slower and more stable and shifts the body out of heightened alertness and into a more regulated baseline state.

Sandalwood through history

For thousands of years, sandalwood has been valued in practices requiring stillness, focus, and presence.

In ancient India, it was applied in rituals, meditation practices, and as a cooling paste on the skin to support calm and concentration.

In Buddhist traditions, sandalwood incense was burned to encourage sustained attention during meditation.

In traditional Chinese practices, it became associated with balance and internal regulation.

Across cultures, its role has remained remarkably consistent.

Not to stimulate the system.

But to reduce noise within it.

Not through activation.

Through stillness.

What neuroscience now describes as autonomic nervous system regulation was, for centuries, approached through ritual, repetition, and sensory experience.

The NEH Ritual

At NEH, scent is used as a way to influence your inner state and, from there, the way you move through your outer world.

With sandalwood, the practice is centered around grounding and slowing down the system.

The ritual:

• Apply the fragrance with an intention.

• Pause and allow the scent to settle.

• Play the frequency music created for the fragrance.

• Read the affirmation slowly and notice how your body responds.

• Take a deeper breath and allow the nervous system to slow down.

With sandalwood, this ritual can be especially supportive during moments of overstimulation, mental fatigue, or when attention feels scattered.

Over time, the body begins to associate sandalwood with a state of regulation.

And through repetition, that response often becomes easier to access.

The Fragrances

Sandalwood can be found in:

The Opening – a creamy, smoky sandalwood that invites you into possibility, curiosity, and new beginnings.

The Vibration – a luminous blend of rose and sandalwood that serves as a reminder that love is not something we need to seek outside ourselves, but something we can always return to within.

Created to create you.
