Olfaction, Emotion & Well-Being

The Art and Science of the Olfactive Setting

Fragrance is usually discussed in terms of beauty.

We speak of flowers and woods, texture and diffusion, elegance and sensuality, memory and place. Yet beneath the artistry of perfume lies something more fundamental.

Olfaction is part of the way we experience ourselves and the world around us.

An aroma can bring forward a place we thought we had forgotten. It can change the character of a room. It can make something feel familiar, intimate, distant, invigorating, or still. Sometimes that response seems to occur before we have even found words to describe what we are smelling.

My work brings together two disciplines that have shaped me: perfumery and lifestyle medicine.

Perfume is not medicine, and fragrance should not be presented as a treatment for disease. But both disciplines raise a shared question:

How does the environment we create around ourselves influence the way we experience our lives within it?

An Earlier Question: Dr. Edward Bach

Nearly a century ago, physician Edward Bach explored the relationship between emotional state and well-being.

Trained in conventional medicine, Bach later developed a philosophy centered on emotional harmony and individual experience. He created a system of 38 flower remedies associated with different emotional states. His writings include Heal Thyself, Free Thyself, and The Twelve Healers and Other Remedies.

Bach’s ideas remain historically and philosophically significant, particularly his attention to emotional experience and well-being. It is also worth noting that the placebo-controlled trials summarized in systematic reviews largely examined defined, standardized outcomes, including examination anxiety and ADHD-related behavior or performance. Those studies did not show effects beyond placebo for the endpoints tested. They were not designed, however, to evaluate every dimension of subjective experience that interested Bach.

However, the underlying question remains relevant:

Do emotional states influence our experience of well-being?

Where Bach Ends and Evidence Begins

Modern research does not support Bach flower remedies as medical treatments. Contemporary neuroscience and psychology do, however, support something important:

Emotion, memory, and sensory perception are deeply interconnected.

The Emotional Sense

Olfactory processing has close anatomical and functional relationships with brain systems involved in emotion, memory, and associative learning. The relationship is reciprocal: odors can influence mood and emotion, while expectation, context, and emotional state can shape odor perception.

We are not passive recipients of scent—we participate in it.

Memory Has an Aroma

Odors can be powerful cues for autobiographical memory. Odor-evoked memories may feel unusually vivid and emotionally engaging, although comparisons with visual, verbal, or auditory cues vary with the way memories are elicited and studied.

This intimate relationship between scent and recollection is often called the “Proust phenomenon.” A fragrance can become inseparable from a moment in life.

The memory is not in the perfume. We place it there.

The Individual Completes the Perfume

There is no simple, universal emotional language of scent. While individual responses vary, population-level patterns do exist in how odors are perceived. At the same time, memory, culture, context, expectation, preference, and personal history help shape what a fragrance means to a particular person.

The same perfume can therefore carry a different meaning for each individual.

From Aromatherapy to Aromachology

Aromachology is a term used for the study of the psychological and behavioral effects of odor. It overlaps with research in olfaction, psychology, neuroscience, and consumer science.

Researchers ask how scent may influence mood, cognition, and perception under controlled conditions. The literature remains complex, and findings often depend on the odor, its intensity and pleasantness, the method of delivery, the setting, and the individual.

Fragrance does not function as a simple emotional switch.

Aroma and the Body

Studies have measured odor-related changes in cardiac activity, skin conductance, respiration, and brain activity. These findings demonstrate interaction between scent, perception, and the nervous system. They do not, by themselves, establish therapeutic efficacy or predictable health benefits.

Lavender as an Example

Lavender preparations have been studied in relation to relaxation and anxiety, but the studies use very different formulations and routes of administration, including inhaled essential oil, massage, and standardized oral preparations. These should not be treated as interchangeable with one another—or with fine fragrance.

Some findings are promising, but reviews also identify substantial variation in study quality, delivery method, and outcome. The evidence does not justify a claim that lavender perfume treats anxiety.

A Developing Science

Research continues to explore how aroma exposure may influence mood, cognition, and perception. Outcomes can depend on concentration, duration, delivery method, context, expectation, preference, culture, and individual differences.

This is a field of complexity, not certainty.

From Perception to Composition

Emerging research is also beginning to examine something especially relevant to perfumery: how the perceptual character of individual odorants relates to our experience of a complex mixture.

A 2026 study published in the Proceedings of the National Academy of Sciences found that models incorporating semantic descriptions of odor, the qualities and associations we use to describe what something smells like, were particularly effective in predicting perceptual relationships between complex odor mixtures.

By combining psychophysical data with machine-learning models, this work can identify population-level patterns in how complex odor mixtures are perceived; it does not predict the emotional response of any particular individual.

This does not mean that the experience of a perfume can be reduced to an equation. But it suggests that the perceptual qualities of individual materials contain meaningful information about the character of the larger olfactory whole.

For me, this is particularly compelling because I often work in the opposite direction. Before beginning a formula, I write the setting I intend to create, sometimes at considerable length. The place, atmosphere, movement, temperature, emotional character, even the imagined light are considered before the materials are chosen.

The formula then becomes a way of working backward from that imagined perceptual world toward the materials capable of creating it.

This is where emerging olfactory science and the art of perfumery begin to have a particularly interesting conversation.

The Olfactive Setting

I describe my approach as the creation of an Olfactive Setting.

An Olfactive Setting is an intentionally composed aromatic environment designed to support a quality of experience. It is not therapy, and it does not prescribe an emotional outcome. Instead, it creates conditions that may invite experiences such as:

  • Stillness
  • Focus
  • Intimacy
  • Transition
  • Recollection
  • Vitality

The perfumer creates the setting. The individual brings a lifetime to it.

Perfume as Ritual

Applying fragrance is a small but intentional act. Through repetition and association, it can become connected with moments, transitions, and states of being.

Perfume becomes part of the architecture of daily life.

Returning to Edward Bach

Bach’s attention to emotional experience remains conceptually interesting. Contemporary science gives us a more rigorous way to explore relationships among smell, memory, emotion, context, and expectation. My own work enters that conversation through the Olfactive Setting: fragrance constructed to invite experience, never to prescribe it.

Fragrance matters—not as medicine, but as experience.

A Different Purpose for Fragrance

This work is not about “healing perfumes.” It is about creating intentional sensory experiences. Fragrance can invite reflection, recollection, presence, and attention.

The experience is not dictated by the perfumer. It is completed by the individual.

Important Note

Pictura Fragrans fragrances are artistic compositions. They are not intended to diagnose, treat, cure, or prevent any disease, and they are not a substitute for professional medical care. Individual responses to fragrance vary widely.
