Essential oils in the emotional brain Part I ;
Unlike other senses, our sense of smell has direct emotional processing centers in the brain, including the amygdala neuronal pathways, the hippocampus and orbitofrontal cortex (OFO). This makes detection of odor intricately related to emotions. 03.01
Many people have experienced firsthand how pleasant or unpleasant odors affect your mood. However, it is also important to note our mood can actually affect our detection fragrances as well!
Indeed, a small study examined odor processing (using the olfactory emotional trial, which assesses whether the person found the pleasant aroma, and odor detection tasks) in relation to the stimuli of anxiety to evoke. They also used a functional magnetic resonance imaging (fMRI) to measure brain response in subjects to stimuli and aromas. They found that by inducing a state of anxiety in the volunteers, the smell of the previous neutral odor became unpleasant and difficult to detect when participants were afraid. The authors summarize the importance of environmental context rich as follows:
Furthermore, sensory (particularly smell) perception does not occur in a vacuum but in a rich context of physiological and psychological internal (; Barsalou, 2008; Barrett and Bar, 2009 Cabanac, 1979) states. 1
Moreover, there is no evidence that the smell of a perfume may be something that can trigger a fear response or calm, in connection with the connections within brain. In fact, a rodent study in 2013 showed how an environmental stimulus induced fear (shock delivery) associated with the smell of peppermint oil in rodents mamma created the same fear response in Peppermint in their small, rodents scared baby. 2.3 (This may be why some people just do not like certain smells and may have no conscious recollection why.)
Interestingly, one study showed positive effects odors welcome. Researchers measured the physiological markers, such as an immune signaling molecule (IL-2) and heart rate in relation to the “nostalgic smells” and found beneficial effects. 4
This literally means that an aromatic oil could calm a person while triggering another. For example, if a person attributes the scent of a generally recognized soothing oil, lavender, so unpleasant, they can get watered smell. Therefore, although generalizations can be made with most essential oils such as lavender has a pleasant and relaxing effect, the preference of the person should also be considered.
In my previous article , I spoke of the various considerations for choosing an essential oil therapeutic quality. These secondary metabolites of powerful herbs contain powerful health and immune modulating properties have been verified in vitro and some clinical trials. 09.05 This means that not only the smell of essential oils evoke emotional effects, but also produce physiological effects beyond odor. This is due to the transfer of molecules in the bloodstream after inhalation.
According to The therapeutic benefits of essential oils, Nutrition, Health and Wellness, essential oils can act biochemically, physiologically, and psychologically. These modes of action can be explained as follows: 10
An example is the interaction of components of essential oil citral, geraniol, nerol, eugenol with estrogen receptors in high concentrations, but not at low concentrations. This study suggests that the dose is an in vitro effects of essential oils factor. 11
However, it is also important to consider the effect of modulation of phytoestrogens. Specifically, it has been found that phytoestrogens are modulators selective estrogen receptor (SERMs), with to greater preference for beta estrogen receptor (ER-B) of estrogen receptor alpha (ER -to). This has an effect of estrogen balance generally by blocking the estrogen receptors potent. Phytoestrogens may also modulate aromatase, increase sex hormone binding globulin, and the effect of other enzymatic pathways. 12-14 Therefore, the previous study could exhibit preferential binding due to high concentration.
An example is the effect of the components in the fennel to balance hormones and help with breastfeeding. 15 Other studies have demonstrated the use of essential oils massage, which contain compounds that modulate muscle spasm, stress, circulation and contain phytoestrogens to help in relieving menstrual discomfort. 16-17
it is important to note that a psychological action usually also has a physiological or biochemical impact on the body. For example, hormonal support could be provided to calm the excitement of inhalation, making stress hormones or enzymes, and providing direct result of phytoestrogens that modulate estrogen levels physiological effects, as noted above.
In a study of 22 postmenopausal women in their 50s changes in the concentrations of neurotransmitters, cortisol and thyroid stimulating hormone in relation to inhalation of sage oil were examined. It was found that this oil inhaling 5-hydroxytrptamine (monoamine, serotonin), decreased cortisol, and mood state alleviated increased. 18
In another randomized study of sixty-three healthy postmenopausal women, researchers found that inhalation of essential oil of neroli (bitter orange) excreted positive effects on menopausal symptoms, stress and estrogen levels. 19
As you can see, essential oils have a profound effect on the modulation of mood and emotion in a variety of ways. They can be very powerful to not only affects the welfare, but also the physical markers affected by unbalanced psychological states. The use of essential oils along with the individualization of nutrition, lifestyle, and balance all body systems, as I review in my new book, BreakFree Medicine , can have profound effects.
In the next blog, I’ll go into more detail about the use of essential oils mood.
