Continuous Inhalation of Essential Oil Increases Gray Matter Volume
August 30, 2024
Aromatherapy is one of the traditional remedies that uses essential oils extracted from plants based on their scent effects and is currently used in many fields. Aromatherapy is based on the theory that inhaling or absorbing essential oils causes changes within the limbic system, the part of the brain associated with memory and emotion. Aromatherapy stimulates physiological responses in the nervous, endocrine, or immune systems and can affect heart rate, blood pressure, breathing, brain wave activity, and the release of various hormones throughout the body. The limbic system comprises subcortical (amygdala, hippocampus) and cortical structures (parahippocampal cortex, cingulate cortex, etc.) and plays a central role in emotional regulation and memory.
