Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an oral hypnotic, a hypnotic food and drink, and a hypnotic diet. More specifically, the present invention is characterized by containing sandalwood essential oil as an active ingredient, and has the effect of promoting sleep and deep sleep for humans and animals who cannot obtain normal sleep due to stress or mental irritability. The resulting oral hypnotics, foods and beverages.

2. Description of the Related Art In recent years, the development of industry and the accompanying changes in the living environment have resulted in physical and psychological stimuli, that is, a lot of stress on animals, including humans and pets, as the term "stress society." ing. As society becomes more complicated, more and more humans have complained of insomnia, such as difficulty falling asleep or not being able to sleep, even though specific lesions such as organic lesions are not found. Is thought to be due to stress.

[0003] When this symptom is severe, that is, as a remedy for insomnia that requires hospital visits, sleep-inducing drugs such as tranquilizers are used. However, these drugs are dramatic and have many drawbacks in that they have many side effects. is there.

[0004] On the other hand, in aromatherapy which has been known for a long time mainly in the European region, a method of eliminating insomnia by various scents of essential oils has been widely reported ("practical aromatherapy": by Charli Price, Takayama Translated by Taro Hayashi, 1987
("Aromatherapy" by Robert Tisland, translated by Rintaro Takayama, 1985).
There have been many reports on the effects of scents on physiological and psychological states. For example, Koga reports on the effects of aromatherapy in terms of brain function (Chemical Technology, 1990
August) (Fragrance Journal, No.86, 1987)
) And a report on the relationship between scents and consciousness by torii gates (Fragrance Journal, No. 77, 16, 1986). It has also been reported that the fragrances of bitter orange essential oil, basil oil, jasmine oil and the like have a sleep-inducing or sleep-promoting effect (JP-A-4-128234, JP-A-4-128234).
149136).

[0005] However, the sedation and sleep-inducing effects of these conventional fragrance therapies are caused by the odor of each essential oil stimulating the olfaction of humans and animals, and the scent of the fragrance is smelled from the nose. Limited to how they are used. This is because it has been conventionally thought that a specific transmission pathway of the brain olfactory pathway is involved in the mechanism of action of the fragrance such as anti-stress and antidepression.

[0006] The limbic system is an organ responsible for controlling instinct, joy, sadness, anger, surprise and the like, and autonomic nervous function. While closely communicating with the hypothalamus, the emotion and related physical reactions are involved. Is deeply involved in The secondary nervous system of the olfactory tract emanating from the mitral cells of the olfactory bulb is directly input to the limbic system, and the stimulus (scent) received by the olfactory sense is related to the control of emotions and autonomic nervous functions. [Stress and aromatherapy, Yoshihiko Koga (Fragrance Journal, No.86, 1
987), Trial of treatment of depression by fragrance-Scientific verification and clinical application, Komori, Fujiwara et al. (Japanese Journal of Neuropsychopharmacology, Vo)
l. 15, 39-42, 1995)].

On the other hand, sensitivity to fragrance and "like
It is also true that there is a clear individual difference in tastes such as “dislike”. When you smell the smell you like, you can get emotional effects such as ease of mood, relief, concentration, etc. On the other hand, smelling the smell you hate may be frustrating or uncomfortable. In addition, it has been reported that emotional and psychological factors based on tastes are greatly related to changes in electroencephalograms centered on α-waves, autonomic nervous functions, etc. Physiological studies, Takami Yagyu (FOOD & FOOD INGREDIENTS JOUR
NAL No.156, 1993), EEG topography, Norio Torii (Fragrance Journal, 15-19, 1992-10)].

Accordingly, a hypnotic effect can be stably expected without being affected by individual sensitivity or taste, etc., and unlike a tranquilizer used conventionally as a sleeping pill, a safe sleep-promoting agent having no side effects, The development of agents is desired.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide an oral hypnotic which contains sandalwood essential oil as an active ingredient and is used orally.

[0010] Another object of the present invention is to provide a hypnotic food and drink and a hypnotic bait characterized by containing sandalwood essential oil.

[0011]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned conventional problems. Unexpectedly, a specific essential oil such as sandalwood essential oil has been used for the conventional olfactory and oral mucosa. It has been found that an excellent hypnotic effect is exhibited by absorption into the body through the gastrointestinal tract by oral ingestion rather than absorption from the lungs.

Although sandalwood essential oil is used for anxiety and antidepressant in the field of aromatherapy (aromatic therapy), it has been reported that its fragrance component can hardly be expected to have a good sleep promoting effect ( JP-A-4-14913
No. 6). Also, because of the aromatic nature of the incense, there is a strong individual difference between likes and dislikes.

[0013] Under these facts, the above findings by the present inventors were just surprising. The present invention has been developed based on this finding.
