    ability to pursue objectives without the individual's conscious awareness (p. 237) .  The olfactory system's connection to the brain's primitive centers suggests that scents could subtly influence these unconscious goals, steering emotions, preferences, and behaviors.  The idea that the nasal cycle allows the unconscious mind to selectively examine scents by preferentially directing scent data to either the right or left hemisphere is intriguing (p. 238). www.drbonci.com 120
  78. Addressing Unconscious Needs Scent wields an almost ethereal power capable

    of transcending the boundaries of conscious thought to touch the deepest parts of our being (p. 239) .  The unconscious mind sifts through our past experiences, hopes, fears, and desires to influence our behavior in ways that are sometimes mysterious to our conscious selves (p. 240).  Floral scents can subtly influence our behavior by aligning with our unconscious needs and desires (pp. 241- 242). www.drbonci.com 122
  79. Unconscious Scent-Seeking Many report craving the smell of certain foods,

    flowers, or other natural elements when ill, a behavior that could be rooted in an instinctive search for comfort or healing (p. 248) .  Similarly, people might seek out scents associated with positive memories during times of stress or sadness, unconsciously leveraging the power of scent to evoke a sense of safety or nostalgia.  The basal ganglia governs unconscious goal setting, orchestrating a complex interplay between motivation, emotion, and action (pp. 278-279). www.drbonci.com 123
  80. Olfaction-Basal Ganglia Axis Olfaction is believed to be conveyed through

    the olfactory tubercle and amygdala to the basal ganglia (BG) via the ventral striatum.  At the heart of reward-based learning lies the dopamine system, intricately connected with the BG— a set of subcortical structures crucial for movement and decision-making (pp. 279-280). www.drbonci.com 124

    all them teeth and no toothbrush.” ~ Bobby Boucher ~ www.drbonci.com 126
  83. Client Interview The journey begins with an in-depth consultation, where

    the aromatherapist invites the client to share their concerns and challenges (pp. 310-311) .  The act of voicing concerns aloud helps clarify the client's situation for the aromatherapist and allows clients to acknowledge and prioritize their issues, often bringing subconscious worries into the light.  As clients articulate their concerns, their subconscious priorities emerge, guiding the therapeutic process. www.drbonci.com 127
  84. Avoid Information Overload With the vast array of essential oils

    available, each boasting different health benefits and aromatic profiles, the potential for information overload is significant (pp. 286-287) .    Unconscious goal setting acts as a protective filter, prioritizing scents that align with an individual's intrinsic needs and previous positive outcomes. www.drbonci.com 128
  85. Subconscious Scent Selection When selecting a floral essential oil, the

    limbic system plays a pivotal role by assessing the emotional significance of each scent (pp. 284-285) .  This primal part of the brain processes the emotional valence of the aromatic compounds, triggering memories and emotions associated with similar scents.  The basal ganglia integrate this emotional feedback, prioritizing actions—like choosing a particular essential oil—that align with internal goals, such as seeking relaxation or stimulation. www.drbonci.com 129
  86. Curated Selection Armed with insights from the client's history, the

    aromatherapist curates a selection of five floral essential oils that resonate with the client's emotional and physical state (p. 311) .  This personalized collection is thoughtfully presented on test strips, minimizing external distractions and focusing the client's attention on the olfactory experience.  As the client samples each fragrance, their subconscious reactions—mediated by their innate preferences and emotional responses—come to the fore. www.drbonci.com 130
  87. Micro-Expressions "Emotions Revealed" by Paul Ekman (2003) is a groundbreaking

    book that delves into the complex world of human emotions and their expressions (p. 295) .  Micro-expressions are subtle, rapid, and involuntary facial expressions that occur as fleeting responses to emotional stimuli, lasting typically less than half a second (p. 297).    Happy, sad, fear, anger, surprise, disgust, and contempt. www.drbonci.com 132
  88. Reading Emotional Responses Observing the client's immediate reactions to each

    fragrance is the key to identifying the optimal scent (p. 312) .  Positive micro-expressions, such as a subtle smile or a relaxed posture, signal a deep emotional resonance with a particular scent.  These involuntary cues offer invaluable insights into the client's subconscious preferences, highlighting the fragrances that align with their current emotional and physiological needs. www.drbonci.com 133
  89. Spectrum of Happiness As understood through Ekman's research, happiness is

    not a monolithic emotion but a spectrum that captures many positive emotional states (p. 300) .  Each point on this spectrum—from the serene satisfaction of contentment to the exhilarating heights of ecstasy—offers a unique blend of feelings, all contributing to the overarching experience of happiness.  This diversity acknowledges that happiness is experienced subjectively and can manifest in myriad ways depending on the individual, the context, and the intensity of the emotion. www.drbonci.com 134
  90. A Note on Surprise A client may experience a moment

    of surprise upon encountering a floral fragrance triggered by the unexpected beauty or intensity of the scent (pp. 306- 307) .  While short-lived, this initial surprise reaction opens the door to a more nuanced emotional response, quickly giving way to the relevant micro-expression that signifies the underlying emotional impact of the scent. www.drbonci.com 136
  91. The Final Selection The scent that elicits the most favorable

    response from the client, marked by positive micro- expressions and a sense of emotional affinity, is deemed the most suitable choice (p. 312) .  This fragrance, selected not just by the client's conscious preference but by their entire nervous system and emotional landscape, becomes the cornerstone of their aromatherapy journey.  It embodies the client's ideal pathway to enhanced well- being, encapsulating the therapeutic power of scent to harmonize mind, body, and spirit. www.drbonci.com 138
