DIY Calming Aromatherapy Spray: Supporting the Limbic System
The limbic system, often referred to as the emotional center of the brain, plays a key role in regulating mood, memory, and emotional balance. For women, this part of the brain can often feel "busier," due to a combination of biological, hormonal, and societal influences. A groundbreaking study published in the Journal of Alzheimer’s Disease sheds light on this phenomenon, providing valuable insights into how gender-based differences in brain activity may affect emotional well-being—and why tools like aromatherapy can offer meaningful support.
What the Research Says About Women’s Limbic Brains
In the largest functional brain imaging study to date, researchers at the Amen Clinics compared over 46,000 brain SPECT imaging studies to identify specific brain differences between men and women. The study found that women’s brains were significantly more active in many areas, particularly in the prefrontal cortex (responsible for focus, impulse control, and decision-making) and the limbic system (associated with mood, anxiety, and emotional regulation).
This increased limbic activity may explain why women tend to excel in empathy, intuition, collaboration, and self-control. However, it also makes them more vulnerable to conditions like anxiety, depression, insomnia, and eating disorders, as well as Alzheimer’s disease.
Lead researcher Dr. Daniel G. Amen highlighted the importance of these findings: “This is a very important study to help understand gender-based brain differences. The quantifiable differences we identified... are important for understanding gender-based risk for brain disorders.”
By understanding these differences, tailoring strategies can help women better regulate their emotions and calm an overactive limbic system. One such accessible tool is aromatherapy, which directly interacts with the limbic system through the sense of smell.
Why Aromatherapy Works for the Limbic System
The sense of smell has a unique and direct pathway to the limbic system, bypassing the brain's relay center (the thalamus). This is why aromatherapy has such a profound impact on emotions and stress regulation.
Dr. Daniel G. Amen explains: “Brain messages from all the other senses [sight, hearing, touch, and taste] are sent to a ‘relay station’ before zooming to their final destination in different parts of the brain. Because your sense of smell (via the nose) goes directly to the LS, it’s easy to understand why aroma has such a profound impact on emotions.”
But why is this connection so powerful?
Direct Link to Emotion and Memory: The limbic system houses the amygdala (the brain’s emotional processing center) and the hippocampus (which organizes memories). Smells can activate the amygdala, influencing emotions like calmness or anxiety. At the same time, they can evoke vivid emotional memories through the hippocampus, explaining why certain scents feel nostalgic or comforting.
Immediate Biochemical Effects: Aromas can trigger the release of neurotransmitters like serotonin (associated with happiness) or GABA (which calms the brain). For example, linalool in lavender has been shown to reduce anxiety, while limonene in citrus oils, like bergamot boosts mood and energy.
Evolutionary Roots: Smell evolved as one of the earliest senses to help humans detect danger (e.g., spoiled food, predators) and find safe environments. This deep-rooted survival mechanism explains why smells strongly influence emotions even today.
By leveraging the power of scent, aromatherapy provides a natural, immediate way to calm an overactive limbic system and restore emotional balance. Essential oils like lavender, bergamot, and frankincense directly support this process, offering a soothing and uplifting experience for both mind and body.
Lavender: Known for its ability to calm anxiety and improve sleep.
Frankincense: Grounds the mind and supports emotional resilience.
Bergamot: Uplifts mood and alleviates feelings of sadness or overwhelm.

Combine the rose hydrosol, distilled water, and witch hazel in a small spray bottle.
Add the essential oils, and shake well to mix.
Shake before each use and spray into the air or onto your skin to enjoy its calming effects.
How Aromatherapy Complements Brain Care
The findings from the Amen Clinics study suggest that women’s greater limbic system activity can make them more sensitive to emotional and social cues but also more susceptible to stress-related conditions. This aromatherapy spray is one way to promote calmness and balance, working directly with the limbic system.
However, aromatherapy works best when used as part of a comprehensive toolkit for emotional regulation. Practices like mindfulness, deep breathing, and regular physical activity as well as supplements containing Omega-3 fatty acids and fish oils, containing a higher amount of EPA also support the limbic system and promote resilience against stress.
