In summary, essential oils are believed to have therapeutic effects by stimulating the olfactory system, which is connected to the limbic system of the brain, the part of the brain that controls functions such as breathing, heart rate, blood pressure, memory, stress levels and hormone balance. When you smell essential oils, the body can respond by releasing chemicals into the body. For example, serotonin helps calm the body, endorphins that help it relax by releasing tension in the muscles. Aromatherapy is the practice of using essential oils for therapeutic benefits.
Aromatherapy has been used for centuries. When inhaled, the aromatic molecules of essential oils travel from the olfactory nerves directly to the brain and especially affect the amygdala, the emotional center of the brain. Numerous studies have shown that essential oils affect our emotions. In fact, according to the National Cancer Institute (PDQ), “Studies have consistently shown that odors can produce specific effects on human neuropsychological and autonomic function and that odors can influence mood, health perception, and arousal.
These studies suggest that odors may have therapeutic applications in the context of stressful and adverse psychological conditions. Smithii) essential oil when coughing or inhaling peppermint essential oil (Mentha piperita) to reduce fatigue or nausea. Therefore, it is essential that we selectively pay attention to information relevant to the target while inhibiting irrelevant or distracting information. The amplitudes of P300 in C4, P3 and Oz were significantly higher in the NP condition than in the control condition for the “no essential oil” group.
In terpenes, monoterpenes are the most abundant molecules of essential oils (about 90%) with a wide variety of structures. Therefore, the objective of this study was to use ERP to find out how blended essential oil affected the performance of humans in the task of selective attention. The PLV analysis showed that essential oils induced stronger intracerebral functional connections during the performance of the selective attention task. The potential event-related technique was used to examine the brain mechanisms underlying the effects of blended essential oils on human selective attention.
Several studies have shown that the effects of various fragrances on mood, physiology and behavior are due to the direct and intrinsic ability of the fragrance to interact and affect the central nervous system. They found that the increase in reaction time was significantly lower with lavender than with control, suggesting that lavender essential oil helps to curb a decline in vigilance or, in other words, to maintain sustained attention on long-term surveillance tasks. The results showed that during the inhalation of San-Jo-In essential oil, the EEG spectrum values of fast alpha waves increased by 50%, suggesting that the essential oil was able to alter the activity of the EEG and has positive effects on mood and cognitive functions of the brain. The results of research on the effect of essential oils on short-term human image and numerical memory have been described.
The author found that prolonged inhalation of fragrances affects the parameters of the autonomic nervous system and the states of the brain. Common examples include applying a mixture containing essential oil of black pepper (Piper nigrum) or ginger (Zinziber officinalis) to reduce arthritis pain and improve flexibility, or applying German chamomile essential oil (Matricaria recutita) to treat eczema. The data confirmed that the inhalation of essential oils affected a different subjective sensitivity of the fragrance depending on the type of work. .
