Essential oils in the emotional part of the brain II

Essential oils in the emotional part of the brain II ;

In the first blog, I discussed the biochemical, physiological, psychological and actions of essential oils. In this blog, I’ll dig deeper in some studies that demonstrate the power of essential oils and aromatherapy mood.

In a review article of 2006, “Aromatherapy in the treatment of psychiatric disorders: clinical perspectives and neuropharmacological” the authors highlight several clinical trials and tests in vitro mechanisms in the dual nature of ” indirect “and” “psychoaromatherapy. “Direct effect discussed” aroma. Specifically, this means that the emotional aspect of smell (direct), together with the effects of biochemical constituents (indirect) mood much impact.

For example, in my first blog, I talked about how odors modulate emotions just by our inhalation. However, beyond the sense of smell, the different constituents present in essential oils have been shown in vitro to modulate specific pathways in the brain related to the balance of neurotransmitters and other psychological effects. Moreover, several intriguing clinical trials with Alzheimer’s patients showed impressive improvement in performance, with certain essential oils, especially lemon balm and lavender (chemotype was not specified) in this review. The authors concluded:

conclude that aromatherapy provides a potentially effective treatment for a variety of psychiatric disorders. Moreover, taking into account the information available on the safety, aromatherapy appears to be no adverse effects of many conventional psychotropic drugs. Investment in clinical and scientific research is clearly justified . 1

In another review of sixteen clinical trials related to the use of essential oils and anxiety, the authors stated:

The results are based on 16 randomized controlled trials that examine the anxiolytic effects of aromatherapy among people with anxiety symptoms. Most studies indicated positive effects to ease anxiety. No adverse events were reported. 2

different effects for different oils

Beyond biochemistry and preference of individual odors, as mentioned in the part I, the essential oil can modulate mood differently depending on their effect on the nervous system. In a study of 43 healthy women, various essential oils were tested for their effect on the tone of the nervous system. The authors evaluated the differences between the various essential oils that are inhaled into a ball of cotton verses placebo unscented. blood pressure and spending blood catecholamines, chemical signaling molecules that are made by stress were measured.

According to the study, the following results were found:

  • Black pepper, fennel, tarragon oil, grapefruit and caused a 1.5 to 2.5-fold increase in blood pressure, it is indicating an increase in the activity of the sympathetic nervous system, the part of the nervous system involved in the excitation.
  • rose and patchouli oil decreased activity of the sympathetic nervous system by 40%.
  • pepper oil caused a 1.7-fold increase in measurements of adrenaline in plasma.
  • Rose oil showed lower adrenaline levels by 30 percent. 3

Another way to determine the response of the nervous oils system is proving its impact on work stress by subjective measures of their response, such as heart rate, blood pressure, and measures of heart rate variability (HRV). A Japanese study what he did. The researchers assessed the impact of essential oil of bergamot, used as aromatherapy spray inhaled for 10 minutes, in these parameters in fifty-four primary school teachers in a high stress working population in Taiwan. Measurements evaluated five minutes before and after application of the spray. Interestingly, the authors reported subgroups based on different effects. Specifically, they found positive results for all groups measures degree of moderate and high anxiety; whereas, substitute teachers and degree of light anxiety groups do not appear to show the same amount of modulation. The authors stated,

This study also found that aromatherapy was effective for groups of moderate to severe anxiety. However, there was no statistically significant effect for the group of anxiety light, which was stable for the autonomic nervous activity. aromatherapy function is to drive the autonomic nervous activity toward a steady state; Therefore, not merely physiological change after an aromatherapy treatment . [Emphasis added] 4

Finally, some studies evaluated brain wave patterns after inhalation of essential oils to determine the effects on mood and the central nervous system.

A 2013 study showed both psychological and physiological effects, with jasmine oil. In this test 20 skilful subjects were recruited (several studies have shown that wave activity effects laterality of the brain) to assess the effect of this essential oil on the activities of emotion and brain waves through measurement using an EEG (electroencephalogram). Importantly, the authors also recognized and controlled by the role of “pleasantness of a smell”, which can affect the function of the nervous system, as mentioned.

The results were impressive. Jasmine oil caused an increase in the energy of the beta waves (indicating increased alertness) in the anterior and posterior left brain. Those who inhaled jasmine oil also reported a greater sense of well being and decreased sleepiness compared to the idle condition and control (almond oil.) 5

In another trial with 20 subjects, researchers also evaluated EEG recordings with the skin temperature, heart rate, breathing rate, blood pressure, and evaluations of the moods of the subjects in the pre, during the treatment and post-inhaling rosemary periods and the results compared with control conditions. The results showed a significant increase in blood pressure, heart rate and respiratory rate after inhaling rosemary oil indicating its effect on alertness and sympathetic stimulation. 6

Another psychological and physiological effects of essential oils can be demonstrated in practice forest bath. The smell of volatile compounds trees, phytoncides, has not only been shown to decrease the concentrations of adrenaline in the urine, but also stimulate natural killer cells and substances that promote immune. 7-10

mood and cognition

not only essential oils can modulate mood and affect various biochemical pathways, which have also been studied for cognition.

A randomized study showed the impact of the aroma of essential oils on cognition and mood in healthy individuals. 144 subjects were randomized to evaluate the cognitive impact of any aroma ylang-ylang, mint aroma, or any fragrance (control) using the battery computerized assessment Cognitive Drug Research, 11 tool validated cognitive test, completed with the state of mind the scales and cognitive tests before after 12 researchers found that peppermint improves memory and alertness of subjects .; whereas, ylang-ylang and decreased need peace of mind. The authors conclude:

These results provide support for the claim that the aromas of essential oils can produce significant and idiosyncratic effects on both subjective and objective aspects of human behavior evaluations. They are discussed with reference to possible pharmacological and psychological modes of influence. 11

Other studies have also demonstrated the stimulant properties of peppermint 13-15 One study also supported that peppermint can be exhilarating .; while lavender, as expected, was calming down. 13

Conclusion:

essential oils have effects on the mind and body in forms of synergy and powerful. It is important to use therapeutic essential oils when it comes to achieve not only balance mood, but the positive effects on cognition and physical parameters.
