Description

A composition for relieving stress including pelargonium graveolens oil}

The present invention relates to a composition for relieving stress including rose geranium essential oil, and more specifically, to a composition capable of improving stress relief and psychological stability effects by increasing brain waves by using rose geranium essential oil.

Stress is a state of psychological/physical tension that you feel when you are in an environment that is difficult to adapt. Long-term stress can lead to physical diseases such as heart disease, stomach ulcers, and high blood pressure, as well as psychological maladjustment such as insomnia, neurosis, and depression.

In an industrial society where conflict and competition are fierce, as society changes structurally or functionally, most of the modern people who have to adapt to it are subjected to a lot of physical/psychological stress.

Appropriate stress is the driving force of life and increases efficiency and productivity, so it can also act as a vital energy booster of life. However, stress can act as an important health risk factor because excessive stress can lead to disease or death.

Therefore, recognizing and managing stress is essential for maintaining and improving health.

Stress relief methods that are currently proven effective include psychological or psychotherapy, biofeedback therapy, progressive relaxation therapy, or exercise therapy.

Although these methods cannot remove external stressors directly, they are ways to allow individuals to correctly recognize the various stresses that constantly come in their lives and to be less susceptible to adverse health effects.

Among these stress relief methods, interest in aromatherapy is increasing, and cases of using fragrance to provide a pleasant environment at work or in public places are increasing.

In particular, it is known that the scent substances of aroma essential oil applied to aroma therapy reduce stress and maintain the balance of the autonomic nervous system, thereby further strengthening the immune function that controls diseases or disharmony of the body.

Aroma is a word that includes the physical components and fragrances of essential oils extracted from plants such as herbs and medicinal herbs, and aromatherapy refers to natural or complementary and alternative therapy using aroma.

Aroma essential oil stimulates the limbic system through the sense of smell, and the limbic system influences the autonomic nervous system and the stress neuroendocrine system through the hypothalamus, thereby relaxing the sympathetic nervous system and stress response. Therefore, aroma therapy has been used as a complementary and alternative therapy for mental and physical relaxation and mood change from stress.

Plant essential oils used in aroma therapy can be applied to the skin or massaged to balance sufficient moisture and lipids to the skin.By performing massage with plant essential oils, in addition to the massage effect of relaxing muscles, activating metabolism, and promoting blood circulation, There may be chemical and pharmacological effects of the absorbed perfume itself.

In addition, plant essential oils often have common features such as antiseptic, sterilization, and pain relief in addition to fragrance, so essential oil components absorbed in the capillaries rotate through the bloodstream and can play the role of antibiotics and sedatives.

Aroma therapy will double the effect by increasing the absorption of essential oil through the skin and adding the mental and physical effects of the massage itself, in addition to the action on the central nervous system of the sense of smell through inhalation of fragrance by combining the massage therapy by hand.

In some studies on stress-related aroma therapy, the effect of reducing stress in the working environment was reported through subjective evaluation before and after according to the inhalation method of several aroma oils.

Accordingly, it is necessary to develop a composition that can be used as an aroma therapy and has excellent stress relief and psychological stability effects.
