Description

EEG induction method using aromatherapy

The present invention relates to a method for inducing EEG, and more particularly, to a method for inducing EEG using aromatherapy.

Aromatherapy means aroma therapy, aroma therapy, aroma therapy, etc. It is a combination of'aroma' meaning scent and therapy meaning therapy. Aromatherapy is known to exhibit psychological, physical, and skin aesthetic effects using essential oils extracted from plants.

Such aromatherapy began with the history of mankind, and the literature shows that the ancient Egyptians extracted essential oils from aromatic medicinal plants and used them throughout the fields of religion, medicine, beauty, and cuisine. Afterwards, it was passed down to Greece to further develop the use of essential oils and ointments, and the ancient Romans brought various plants and oils from conquered countries, used them for beauty, bathing, and medical purposes, and expanded their power to Europe. As a result, various medicinal plants spread to Europe.

In the 20th century, research on the scientific aspect became active as the ingredients of essential oils were identified. French chemist Rene Maurice Gattefosse first used the term'aromatherapy' in 1928 and published a book under the same name in 1973. During the Indochina War (1948-1959), doctor, Valnet Jean, used essential oils to have a great effect on wound healing for soldiers. Robert Tisserand wrote the first English aromatherapy book in 1977, TheArt of Aromatherapy, and since then, it has been rapidly known to many people as numerous books have been written.

Essential oils are extracted by applying steam or pressure to ingredients containing essences such as flowers, fruits, skins, leaves, stems, and roots of aromatic plants, and the essences are contained in trace amounts on the surface of plants or in small oil glands within cells. . These essences are highly concentrated, fat-soluble volatile organic compounds with a unique directionality that can be absorbed into the human body through the skin and olfactory senses. They melt into the sebum of the skin and penetrate into the dermis, which is an internal tissue, circulating throughout the body through capillary blood vessels and lymphatic circulation Maintain body rhythm and balance. Essential oils are inhaled and transmitted to the brain through the limbic system of the cerebrum to affect the brain, but they do not accumulate in the body, and escape from the body in various ways such as urine, feces, sweat, and divergence.

In recent years, a method of relaxing or stabilizing the mind and body by using the efficacy of these essential oils is continuously developed. Prior art literature discloses a fragrance composition that relaxes and stabilizes the mind and body, and discloses an oil extracted from the roots of Angelica gigas L. domestically produced by a supercritical extraction method.

However, recent studies are limited to methods of relaxation of the mind and body or alleviating stress, as in the prior art literature. That is, a method of maximizing the awakening effect and further maximizing the immersion state by aromatherapy has not been actively made yet. Furthermore, in this case, even if a qualitative aromatherapy approach is made, the control of aromatherapy to achieve an awakening effect and an immersion effect accurately by actually analyzing the user's brain waves is not performed as well.

Hereinafter, a method of inducing brain waves using aromatherapy according to an embodiment of the present invention will be described.

First of all, the method of inducing brain waves using aromatherapy according to an embodiment of the present invention includes a first step of preparing essential oil, a second step of exposing the essential oil to a user and inhaling it, and a third step of inducing a target brain wave to the user. Includes steps.

At this time, the essential oil according to the present embodiment was prepared by blending sweet orange (Citrus sinensis), lavender, and amiris. In more detail, after blending sweet orange as a top note, lavender as a middle note, and amyris 1:2:1 as a base note, it was stored refrigerated at 4° C. until use.

The main components of sweet orange are monoterpenes such as limonene, beta-myrcene, and alpha-pinene (Tisserand R. et al., 2014). Monoterpene is the most representative organic molecule constituting essential oil and is contained in most oils. Essential oils with a large amount of monoterpene have a low molecular weight, high volatility, and a light top note scent, and are easily oxidized. Sweet orange is known to be effective in relieving depression, tension, and stress psychologically.

Lavender (Lavandula angustifolia) is. Lavender has grayish green spear-shaped leaves and blue flower spikes. Lavender essential oil is obtained by extracting lavender flowers by steam distillation. The main ingredients of lavender are linalyl acetate, linalool, cis-ocimene, and lavandulyl acetate, which contain more than 100 ingredients. Lavender is also the most commonly applied fragrance in aromatherapy products as it calms the mind, helps to relax and sleep comfortably. Psychologically relieves stress, insomnia, anger, and relieves depression.

Amyris balsamifera is a 3-6 m long stalk family plant that grows all over North, Central and West Indies in South America. Amiris essential oil is extracted from the wood of A.balsamifera through steam distillation and has a soothing effect. The main ingredient is sesquiterpene, such as elemol, beta-eudesmol, and epi-gamma-eudesmol. Sesquiterpene is found primarily in woody, root and asteraceae plants.

As such, it can be seen that all of the essential oils according to the present embodiment are related to sedation and relaxation. However, aromatherapy according to this embodiment basically requires an arousal effect or an immersion effect. Therefore, in this example, the above-described essential oil was blended, and the arousal effect and immersion effect at this time were verified through an induced brain wave analysis.

Electroencephalogram (EEG) is an electrical signal generated by the brain, and scalp EEG is a measurement of the spatial potential difference formed on the surface of the head through electrodes attached to the scalp. Basically, the brain waves are composed of delta waves, theta waves, alpha waves, beta waves, and gamma waves, and a more detailed description will be omitted since it has been sufficiently known.

Referring to FIG. 1, the EEG measurement according to the present embodiment was performed by applying the internationally unified 10-20 method to the electrode attachment site. The length of the head is set at intervals of 10% and 20%, and electrodes are placed symmetrically at intersection points, and additional electrodes can be placed by subdividing between intersection points. F is the frontal lobe, T is the temporal lobe, C is the central, P is the parietal lobe, and O is the occipital lobe. Z means the middle of both sides, odd number means the electrode of the left brain, and even number means the electrode of the right brain. The number increases as the distance from the middle line goes from front to back.
In the experimental examples to be described later, 10 healthy adult males and 10 females in their 20s to 30s without olfactory disease were conducted using the same essential oil, and those who took medicine and had a history of surgery were excluded. For 24 hours before the EEG measurement, caution was given to avoid fatigue by taking adequate sleep and rest without taking cold medicines, alcohol and cigarettes.
At this time, to determine how the blending essential oil containing sweet orange, lavender, and amiris oils affects the EEG, the EEG was measured and analyzed for 1 minute before and after inhaling the blending essential oil with the subject's eyes closed. . For EEG during inhalation, apply a 0.5 cm blending essential oil to one end of a 0.7 cm wide and 13.5 cm long smelling strip, place it at 5 cm from the nose of the subject with eyes closed, and smell the EEG for 1 minute. It was measured.
EEG measurements were conducted in a quiet laboratory with a size of 32.4 m2 maintained at about 24°C and 50% humidity. For EEG electrode attachment, 32 channel EEG electrodes were attached according to the 10-20 international standard electrode attachment method. EEG measurement results were stored in a computer in real time through the Telescan (LXSMD61, Laxtha Co. Ltd. Korea) program, and the EEG device QEEE-64FX (LAXTHA Inc. Daejeon, KOREA) was used, and the EEG index item as an experimental example. Was conducted for 25 items as shown in the following [Table 1].

As described above, the blending oil according to the present embodiment has a statistically significant decrease in the AT indicator in the left frontal lobe area (p <0.05), and the AA indicator is in the left frontal lobe, right frontal lobe, left frontal lobe, right frontal lobe, and frontal lobe. Statistically significant decrease in the central region (p<0.05), ASA indicators were statistically significant in the left frontal lobe, right frontal lobe, left frontal lobe, right frontal lobe, frontal center, left temporal lobe, right temporal lobe, parietal, and right parietal lobe. Decreased (p <0.05) to confirm that the brain was awakened. In addition, the SEF50 indicator, which can confirm arousal status, increases statistically in the left frontal lobe and left frontal lobe (p<0.05), and the SEF90 indicator, which can confirm mental load and arousal status, is statistically significant in the left frontal lobe. It was confirmed that the brain was awakened by increasing (p <0.05).

In addition, while the blending oil according to this embodiment induces an arousal state, AFA indicators are statistically in the left frontal lobe, right frontal lobe, left frontal lobe, right frontal lobe, frontal center, left temporal lobe, right temporal lobe, parietal, and right parietal lobe. Significantly increased (p<0.05), RMB index increased statistically in the left frontal lobe, right frontal lobe, and left frontal lobe (p<0.05), and the RG indicator was statistically significantly increased in the left frontal lobe (p By <0.05), it was confirmed that the brain reached an immersion state.

As such, the blending oil according to the present embodiment induces arousal and immersive EEG, and the AB indicator is statistically significantly reduced in the right frontal lobe, left frontal lobe, and right frontal lobe (p <0.05), and the AHB indicator is the right frontal lobe, The left frontal lobe was statistically significantly decreased (p<0.05), indicating that the stress stress in the brain was reduced.The ASEF indicators were left frontal lobe, right frontal lobe, left frontal lobe, right frontal lobe, frontal center, parietal area, In the right temporal lobe, left parietal lobe, right parietal lobe, left occipital region, and right occipital region, statistically significant increase (p <0.05) showed that the brain reached a comfortable and comfortable state.

As described above, the brainwave inducing method according to the present embodiment has an effect of avoiding the conventional relaxation-oriented aromatherapy and inducing arousal and immersion in a work environment, while simultaneously promoting stress reduction, which is a basic effect of aromatherapy.
