Experimental example 1

Test method Tested with ND-97 digital electroencephalograph (Shanghai Hi-Tech Co., Ltd.)

Principle: Brain waves originate from the dendritic electrical activity of the pyramidal cells in the cerebral cortex. It is generally believed that it is the sum of the electric fields generated by the extracellular currents of many neurons. It has become one of the important indicators for evaluating changes in the central nervous system. In current research, according to the frequency of various rhythms found in brain waves, brain waves are divided into the following four types: delta waves with a frequency of 0.5-3.5 Hz, theta waves with a frequency of 4-7.5 Hz, and 8 waves with a frequency of 8 Hz. Alpha waves at -13.5Hz, beta waves at a frequency of 14-30Hz. Although the mechanism of brain wave generation has not been fully ascertained, studies have shown that human mental factors have a great influence on brain electrical activity, and when a person's mental state changes, we can use the potential observed from the scalp to detect Retrieve information about the source of electrical activity in the brain. Among them, when the mind is tense or emotional, the β rhythm is significantly enhanced, and the β wave can be used as an indicator of emotional stability to reflect changes in people's emotions; when the mood is relaxed and the consciousness is concentrated, the EEG is dominated by the α rhythm, and the α wave Rhythm is the basic rhythm of EEG in normal adults; when the human brain is in a low level of arousal or in subconscious activities such as dreaming, hypnosis, and napping, theta waves will be significantly enhanced; when adults are in sleep, its proportion will be obvious improve. Therefore, brain wave analysis can be used to indirectly evaluate people's mental state and certain psychological activities. This type of research mainly wants to evaluate the tranquilizing and sleep-promoting effect of plant essential oils by analyzing the proportion of θ waves in brain waves. The evaluation method has been widely used in the evaluation of the tranquilizing efficacy of drugs.

60 volunteers were recruited among college students. The electrode heads were placed on the volunteers' heads according to the standard method of instrument operation, and the students were asked to inhale bromine single essential oils and compound essential oils with different concentrations. The instrument automatically recorded the EEG. Changes, by analyzing the proportion of θ waves in brain waves, the best embodiment formulas of essential oils with obvious tranquilizing and sleep-promoting effects have been screened out:

Embodiment 1: 70 parts of lemon essential oils, 15 parts of lavender essential oils, 10 parts of Roman chamomile essential oils, 5 parts of benzoin essential oils;

Embodiment 2: 80 parts of lemon essential oils, 10 parts of lavender essential oils, 5 parts of Roman chamomile essential oils, 5 parts of benzoin essential oils;

Embodiment 3: 50 parts of lemon essential oils, 35 parts of lavender essential oils, 10 parts of Roman chamomile essential oils, 5 parts of benzoin essential oils;

Experimental example 2

For 20 college students who report that their sleep quality is poor or difficult to fall asleep, first count the usual sleep time of each student in the past 3 days, and then let them drop the essential oil of the embodiment of the present invention 1-2 on the pillow before going to bed, 1-10 college students adopt the essential oil of the embodiment of the present invention 1, and 11-20 college students adopt the essential oil of the embodiment of the present invention 2, repeat 3 days, count the sleep time every day, get the average value as the data after the test, then use SPSS statistical software Using the paired sample T-test method in the article, a comparative analysis is carried out before and after using the oil to see if there is a significant difference.

Table 1 uses the statistics (unit: hour) of sleep time before and after the essential oil of the present invention

1 2 3 4 5 6 7 8 9 10 Before using oil 4.0 5.0 3. 5.0 4.0 4.5 2.0 4.0 5.0 5.5 after using oil 6.0 5.0 6.5 6.0 6.5 5.0 4.0 4.0 5.5 7.0 serial number 11 12 13 14 15 16 17 18 19 20 Before using oil 4.0 4.0 5.5 3.0 3.5 3.5 4.0 4.5 5.0 5.0 after using oil 4.0 6.0 8.0 6.0 4.0 4.0 4.0 7.5 6.0 5.0

It can be seen from the above table 1 that after using the essential oil of the embodiment of the present invention, it has the effect of significantly prolonging the sleep time, so the essential oil prepared by the present invention has good drug effect and significant curative effect; the essential oil of the embodiment of the present invention can calm the nerves and reduce stress , relieve tension, promote sleep and meditation, and have obvious effects on prolonging sleep time.

The following uses the paired sample T-test method in the SPSS statistical software to conduct a comparative analysis before and after oil use to see if there is a significant difference:

Table 2 Paired T-test results - paired sample test

Two-tailed test probability P=0.000<0.001, so it can be considered that the sleep time after inhaling bromine compound essential oil is extremely significantly prolonged

As can be seen from Table 2, after the test, it can be considered that the sleep time after inhaling the bromine compound essential oil is extremely significantly extended, and the essential oil of the embodiment of the present invention is suitable for people who have difficulty falling asleep, dreamy, easy to wake up, and poor spirits during the day. environment for use.

While particular embodiments of the invention have been illustrated and described, it should be appreciated that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
