The author's purpose is to use 'aromatherapy'
Free from all symptoms

In a city with a lack of natural spaces, we aim to cure all illnesses using 'natural healing', or 'aromatherapy'.
The purpose of this book is to convey the effects of fragrance (aroma) on our body and mind from a medical perspective.
The medical community treats the cause of the disease.
With the goal of ‘eliminating or alleviating the symptoms that appear,’ progress has been made by establishing complementary therapies in oriental medicine.
Cancer, which was once considered incurable, is now becoming a curable disease.
As medical technology advances in the future, many intractable diseases, such as dementia and severe Alzheimer's disease, will become 'curable diseases.'

Aromatherapy is a complementary and alternative medicine for the treatment of various symptoms, and its effectiveness is increasing, and it is being increasingly introduced in many medical institutions around the world.
From now on, I believe that we must quickly work to solidify our position as a leader in integrated medical aromatherapy in Oriental medicine, so that it can lead to improvements and enhancements in patients' quality of life and daily life activities.
The effect of scent on the brain is greater than imagined, and because only a small amount is absorbed by the body, it is known to have fewer side effects on the internal organs or the human body compared to oral medications.

The author says that in today's age of advanced modern medicine, the author wrote this book to make more readers understand that with each passing year, more and more attention is being paid to the effects of 'fragrance (smell)' and expectations are being raised.

Scents act directly on the brain.

You can sense various scents and smells in your daily life.
You can smell freshly brewed coffee, the scent of flowers and plants, and even the scent of water or metal, which should be tasteless and odorless.
So how can we detect different scents and odors? You might say, "Of course we smell with our noses, right?"
That's half true.
You can't detect scents with your nose alone.
You can feel it with your skin and with your various sense organs.
The olfactory field of the brain is responsible for identifying what a smell is.

The human sense of smell is relatively sensitive.
Looking at the time felt by each sense, it is known to be 0.5 seconds for smell, 0.9 seconds for pressure, and 0.1 seconds for hearing.
Fragrance particles delivered to the olfactory field affect memory and emotional states, and in particular, regulate hormonal balance.
This provides evidence that increases the likelihood of physical and emotional healing.
Smelling a fragrant smell makes you feel good, smelling delicious food stimulates your appetite, and smelling a specific smell can enhance your memory by reminding you of the past.

A healthy human sense of smell can distinguish up to 10,000 different scents or odors.
On the one hand, the olfactory organ is designed to tire easily.
For example, in the case of strong smells such as human excrement, such as feces or urine, you become insensitive to them after a few minutes and it doesn't bother you at all.
It is truly a profound mystery of the human body.
Fragrances are small volatile molecules floating in the air, invisible to the naked eye.
There are substances that cannot be detected as smells even though they are the same volatile molecules.
For example, city gas molecules are undetectable by humans.
Because there is no smell, there is a risk that a gas leak may not be noticed and may lead to an accident.
The difference between being able to sense and not being able to sense is whether the olfactory receptors in the olfactory cells can detect it or not.
It is known that there are about 400,000 types of scents discovered by humans so far.

Good news for cancer, the leading cause of death today.
Essential oil components induce natural cell death of cancer cells

Chemotherapy drugs attack cancer cells, inhibit their proliferation, and shrink malignant tumors, but they also attack normal cells.
Chemotherapy drugs are very powerful drugs.
It also attacks normal cells.
Nausea and vomiting, which are representative side effects of anticancer drugs, are physiological defense reactions that expel the foreign substance called anticancer drug from the body.
Additionally, anticancer drugs damage normal cells, causing stomatitis or dermatitis, and sometimes even tissue damage in organs, destroying the body.
In this way, anticancer drugs have significant side effects and ruin the 'quality of life' of cancer patients.
By reducing the dosage of anticancer drugs by combining them with aromatherapy, the pain of cancer patients can be significantly reduced.
Numerous researchers have studied the effects of essential oils on killing cancer cells.

Significant results in improving cognitive function
Create a rhythm of life with fragrance

People with dementia tend to have impaired perception of time and disruption of rhythm.
In a study by Dr. Jimbo and his colleagues, rosemary and lemon essential oils used in the morning were found to stimulate the sympathetic nerves, making the body more active, increasing concentration, and strengthening memory.
Meanwhile, the scent of lavender and sweet orange taken before bed has a calming effect and favors the parasympathetic nervous system, promoting improvement in insomnia and alleviation of anxiety.
Recent research has shown that simply using essential oils that stimulate the sympathetic nervous system during the day can improve dementia symptoms.
When aromatherapy was performed for two hours a day with rosemary, camphor, and lemon in the morning and lavender and sweet orange in the evening, the patient's abstract thinking ability significantly improved during the period.
It was later discovered that when aromatherapy was stopped, the body gradually returned to its original state.
It is believed that essential oils used in the morning stimulate the sympathetic nerves, making the body active, and improving concentration and memory.
Meanwhile, there are reports that essential oils used before going to bed at night have a calming effect and promote the improvement of insomnia and anxiety relief by making the parasympathetic nerves dominant.
Using different essential oils during the day and at night is intended to regulate the circadian rhythm.
Recent research has shown that simply using essential oils that stimulate the sympathetic nervous system can improve dementia symptoms.

The brain is the command center that controls the mind and body.
Fragrance can revive the brain

Not only olfactory, but also visual, auditory, tactile, and gustatory sensory stimuli (the five human senses) are all converted into nerve impulses and transmitted to the brain.
However, the transmission process of smell is relatively short.
The exact reason why the neural transmission process in the sense of smell is shorter than in other senses has not yet been identified.
I think it may be because 'smell' is the thing that animals sense most quickly in order to survive.
For example, weak animals at high risk of being caught and eaten have a highly developed sense of smell.
This is also proven in experiments.
If you give a mouse the scent of a predator, such as a cat or a fox, it will immediately cower and hide.
Also, many animals leave their scent here and there to protect their territory.
Even life-threatening foods, such as those that are spoiled or contain harmful substances, can be identified to some extent by their smell.
Not only do they perceive and avoid danger, but they also determine their reproductive behavior to leave behind offspring based on the pheromones of their partners.
Pheromones are emitted not only by mammals, but also by insects and microorganisms.
When the pheromone emitted by an insect reaches the olfactory receptor, it is sensitive to the sex pheromone like a megaphone and engages in mating.
In contrast, for mammals, smelling does not necessarily lead to behavior.
In particular, smell and memory are closely connected.

If you smell good, you will lose weight.
The scent of grapefruit that controls appetite

Obesity is one of the biggest risk factors for modern people.
Obesity is a major cause of lifestyle-related diseases such as diabetes, high blood pressure, and lipid metabolism disorders.
If left untreated, it can lead to heart disease or cerebrovascular disease.
It is also known that obesity accelerates aging, particularly by promoting oxidation and glycation in the body.
It's not just internal diseases.
Orthopedic conditions such as arthritis and osteoarthritis, as well as knee and back pain, are also caused by obesity.
Obesity has a significant impact on health and lifestyle after middle age.
Citrus essential oils have the effect of activating the sympathetic nervous system.
Therefore, it has been assumed since long ago that the smell of grapefruit has an anti-obesity effect.
A team led by Professor Emeritus Katsuya Nagai of Osaka University (Biochemistry) and Professor Emeritus Akira Niijima of Niigata University (Physiology) discovered the efficacy of grapefruit essential oil through experiments on mice.
The experiment was run for six weeks.
The group that was administered grapefruit essential oil was about 20g lighter than the group that was not administered grapefruit essential oil.
Additionally, mice given grapefruit essential oil ate about 70% less food.
It also had the effect of reducing appetite.
Animal experiments have shown that grapefruit essential oil has a dieting effect.
