Eczema

Prof. Tamura Tatsuji, Keifuku Rehabilitation Center, Japan

“Eczema is used to describe several varieties of skin conditions, which have a number of common features. The exact cause or causes of eczema are not fully understood. In many cases, eczema can be attributed by external irritants.

Let me introduce a patient who recovered from skin disease after consuming the ionized water. This patient suffered 10 years of eczema and could not be cured effectively even under specialist treatment. This patient, who is 70 years of age, is the President of a vehicle spare parts company. After the war, his lower limbs suffer acute eczema, which later became chronic. He was repeatedly treated in a specialist skin hospital.

The left limb responded well to treatment, but not so on the right limb. He suffered severe itchiness, which, when scratched led to bleeding. During the last 10 years, he was seen and treated by many doctors. When I first examined him, his lower limb around the joints was covered with vesicles. Weeping occurred owing to serum exuding from the vesicles.

I advised him to try consuming ionized water. He bought a unit and consumed the ionized water religiously and used the acidic water to bathe the affected areas. After 2 weeks of treatment, the vesicles dried up. The eczema was completely cleared without any relapse after 1 1/2 month.”

Allergy

Prof. Tamura Tatsuji, Keifuku Rehabilitation Center, Japan

“Mr. Yamada, the head of Police Research Institute, suffered from severe allergy. He was treated repeatedly by skin specialist, but with no success. Then he started consuming ionized water. The allergy responded very well and was soon completely cured. No relapse had occurred, although he had taken all kinds of food. He was most grateful and excited about this treatment.

As for myself, I had also suffered severe allergy. Ever since I began to consume ionized water, the allergy has recovered. Since then, I started a research on the effectiveness of ionized water.

I discovered that most allergies is due to acidification of body condition and is also related to consuming too much meat and sugar. In every allergy case, the patient’s antioxidant minerals are excessively low which in turn lower the body resistance significantly. The body becomes overly sensitive and develops allergy easily. To stabilize the sensitivity, calcium solution is injected into the vein. Therefore, it is clear that the ionized water has ionic calcium, which can help alleviate allergy.

The ionic calcium not only enhances the heart, urination, and neutralization of toxins but controls acidity. It also enhances the digestive system and liver function. This will promote natural healing power and hence increase its resistance to allergy. In some special cases of illness, which do not respond to drugs, it is found, it is found to respond well to ionized water.”

Diarrhea

Dr.Testsuji Hokudou, Director of Gastroenterology, National Ohkura Hospital

According to double-blind clinical tests comparing effects against various disorders, alkaline ionized water showed significantly more cases of effective results against chronic diarrhea than clean water group. Alkaline ionized water was effective in 94.1% of the volunteers.

Osteoporosis

Alkaline Ionized water helps promote osteogenesis

Metabolic disorder of calcium is considered to be one of the causes of osteoporosis that has an increasing number of cases these days. Therefore we conducted a series of tests by feeding rats with different amounts of calcium and gave them tap water, calcium lactate solution and alkaline ionized water at leisure. According to examination of their bone and blood composition, osteogenesis rate was found in the ascending order of tap water, calcium lactate solution, and alkaline ionized water.

Especially under the condition of low calcium levels in the feed, alkaline ionized water was considered to great effects on improved osteogenesis.

Constipation

Dr. Testsuji Hokudou, Director of Gastroenterology,
National Ohkura Hospital

Alkaline ionized water and clean water was given to 163 volunteers who suffered from abdominal discomfort at the amount of 500ml per day for four weeks.

Overall rate of improvement was significantly higher for those who were given alkaline ionized water.

As a result of comparative double blind clinical tests, alkaline ionized water was proved to be effective against constipation, and most importantly its’ safety was verified. It is considered a departure for using medication where side effects are unavoidable to a certain extent.

The effectiveness of alkaline ionized water is very high at 80.5%.

Gout / Arthritis

“Many different forms of arthritis and gout are the result of acid accumulation in the joints. Heavy people add more pressure on their joints, thus speeding up wear and tear; however, a young person seems to do fine even if he is heavy. It is the accumulated acid that damages cartilages and irritates the joints. Unfortunately, the joints are where the blood cannot carry out wastes easily.

Gout is the accumulation of uric acid in the joints. According to Webster, gout is a disease resulting from a disturbance of metabolism, characterized by an excess of uric acid in the blood and deposits of uric acid salts in the tissues around the joints, especially of the feet and hands: it causes swelling and severe pain, especially in the big toe.

In today’s medicine, there is no effective treatment for these types of degenerative diseases. Because it is painful, one instinctively takes pain killers; however, aspirin types are acidic and they can further irritate the joints.

The sooner we accept the fact that these diseases are the result of too much acidic waste, the sooner we will find the cure for these problems.” Page 58 of Dr. Sang Whang’s book “Reverse Aging”.

Alkaline Water Dissolves More Uric Acid

Since uric acid is one of the primary contributing factors to the painful symptoms experienced by gout sufferers. Therefore, controlling the production of this substance is key to getting symptoms under control. One of the techniques that are now being used to accomplish this is by changing the pH level of the body in order to manipulate its uric acid production.

pH stands for the power of hydrogen and refers to the acidity level in the body. That is, when the pH levels of the body are raised, it becomes more alkaline, while lowering pH levels makes the body more acidic.

Therefore, by raising the pH levels in your body, you are effectively putting into practice a natural gout treatment. The theory behind this is that by making the body more alkaline, the uric acid levels will be reduced.

This is because uric acid can be diluted by drinking water, and the more alkaline the body is, the more water-soluble uric acid becomes. And so, the higher the ratio of alkaline to acid in the body, that is, the higher the pH level of the body (or the number on the pH scale) the more alkaline your body will be, and the more uric acid will be dissolved into the water you drink.

If the uric acid level of the body is kept below a certain level (6.0mg/dL for men and slightly less than that for women) then gout crystal formation will be much less likely to occur.In order to make your body more alkaline, the most commonly recommended technique is to drink alkaline (ionized) water.This is water that has additional OH oxygen as opposed to O2. You can drink it or cook with it.

Diabetes

The first clinical test conducted in Korea shows that water can control diseases!

3 December 2003: The Natural Medicine Research Institute of Hansuh University had invited 15 patients suffering from diabetes and started a clinical test for them.

The scientists divided the patients into two different groups; they stopped insulin treatment completely for the first group of the patients, and they had them drink the Ionized Water (ARW) instead, and the other group of diabetics had been allowed to continue their hospital treatment as well with receiving insulin as usual.

The blood glucose levels have been lowered on the whole, and the blood glucose levels, which had shown wide variations daily before were being stabilized. But the blood glucose levels for those who had not taken the Ionized Water (ARW) but continued receiving insulin everyday under the hospitalized state continued to show wide variations with their blood glucose level.

7 January 2004: Comparison of blood glucose levels before and after experiment conducted. 5 litters ARW/day administered for the 2nd group of patients.

A significant decrease of blood glucose levels for all patients on AKW. Some examples are:

1. Patient Lee, 14 years old, blood glucose level: 250 After drinking the Reduced Water for 36 days: blood glucose level: 204

2. Patient Hwang, 17 years old, blood glucose level: 254 After drinking the Reduced Water for 36 days: blood glucose level:144

3. Patient Lee2, 9 years old, blood glucose level: 324 After drinking the Reduced Water for 36 days: blood glucose level: 210

4. Patient Lee3: 20 years old, blood glucose level: 400 After drinking the Reduced Water for 36 days: blood glucose level: 168

The experiments indicated that the effectiveness of Ionized Water (ARW) was better than insulin.

Prof. Kuwata Keijiroo, Doctor of Medicine, Japan

“When I was serving in the Fire Insurance Association, I used to examine many diabetic patients. Besides treating them with drugs, I provided them with ionized water. After drinking ionized water for one month, 15 diabetic patients were selected and sent to Tokyo University for further test and observations.

Initially, the more serious patients were a bit apprehensive about the treatment. When the ionized water was consumed for some time, the sugar in the blood and urine ranged from a ratio of 300 mg/l to 2 mg/ dc. There was a time where the patient had undergone 5 to 6 blood tests a day and detected to be within normal range. Results also showed that even 1 1/2 hour after meals, the blood sugar and urine ratio was 100 mg/dc 0 mg/dc. The sugar in the urine has completely disappeared.”

NOTE: More Americans than ever before are suffering from diabetes, with the number of new cases averaging almost 800,000 each year. The disease has steadily increased in the United States since 1980, and in 1998, 16 million Americans were diagnosed with diabetes (10. million diagnosed, 5.4 million undiagnosed) Diabetes is the seventh leading cause of death in the United States, and more than 193,000 died from the disease and its related complication in 1996. The greatest increase-76 percent occurred in people age 30 to 30.

Weight Management

Prof. Hatori Tasutaroo, Head of Akajiuiji Blood Centre, Yokohama Hospital, Faitama District

“Due to a higher standard of living, our eating habits have changed. We consume too much proteins, fats and sugar. The excess fats and carbohydrates are in the body as fats. In the present lifestyles, Americans are more extravagant a food compared to the Japanese. Due to this excessive intake obesity is a significant problem. Normally, one out of five males and one out of four females are obese.

The degree of “burn-out” in food intake largely depends on the amount on intake of vitamins and minerals. When excessive intake of proteins, carbohydrates and fats occurs, the requirement for vitamins and minerals increases. However, there is not much research carried out pertaining to the importance of vitamins and minerals.

Nowadays, many people suffer from acidification that leads to diabetes, heart diseases, cancer, liver and kidney diseases. If our food intake can be completely burned off, then there is no deposition of fats. Obviously, there will be no acidification problem and hence there should not be any sign of obesity.

The ionized water contains an abundance of ionic calcium. This ionic calcium helps in the “burn-off” process. By drinking ionized water, it provides sufficient minerals for our body. As a result, we do not need to watch our diet to stay slim.

Hence, ionized water is a savior for those differing from obesity and many adult diseases, providing good assistance in enhancing hood health.”

High Cholesterol

Prof. Kuninaka Hironage, Head of Kuninaka Hospital

“Too many fats in the diets, which lead to the deposition of cholesterol on the blood vessels, which in turn constrict the blood flow, cause most illnesses such as high blood pressure. In accordance with the theory of Professor Gato of Kyushu University on Vitamin K (because vitamin K enables the blood calcium to increase),or the consumption of more antioxidant water, the effectiveness of the increase in the calcium in high blood pressure is most significant.

The consumption of alkaline antioxidant water for a period of 2 to 3 months, I have observed the blood pressure slowly drop, due to the water’s solvent ability, which dissolves the cholesterol in the blood vessels.”

“For over 10 years of my experience, my concept toward minerals, especially pertaining to ionic calcium in high blood pressure and other diseases is most significant. In accordance to the theory of medical Professor Gato of Kyushu University on Vitamin K (because vitamin K enables the blood calcium to increase), or the consumption of more ionized water, the effectiveness of the increase in the calcium in high blood pressure is most significant.

Too many fats in the diets, which lead to the deposition of cholesterol on the blood vessels, which in turn constrict the blood flow, cause most illnesses such as high blood pressure. By drinking ionized water for a period of 2 to 3 months, the blood pressure should slowly drop, because the ionized water is a good solvent, which dissolves the cholesterol in the blood vessels.”

Anti-cancer Effects

After injecting malignant skin cancer cells into cancer-free laboratory mice, they supplied the mice with Alkaline Reduced Water, and compared the size of the tumour after a lapse of 20 days.

The results showed the mice, which were supplied with the Ionized Water (ARW) showed the growing speed of the tumour and tumour sizes had been notably reduced as compared to those that had not taken ARW.

Colon Cleanse

Dr Hiromi Shinya, Director, Shinya Medical Clinic, New York

His revolutionary “Shinya Method” has become widely used in colonoscopy procedures worldwide.

“It is widely recognized in the medical profession that a healthy and clean colon is one of the most important precursors to good health and that the great majority of body ailments and diseases originate in an acidic and dirty colon. Water is essential for your health. Drinking “good water;” especially hard water which has much calcium and magnesium keeps your body at an optimal alkaline PH.”

Vascular Heart Disease

Prof. Kuwata Keijiroo, Doctor of Medicine, Japan

“In my opinion, the wonder of ionized water is the ability neutralizes toxins, but it is not a medicine. The difference is that the medicine can only apply to each and individual case. Whereas the ionized water can be consumed generally and it’s neutralizing power is something which is very much unexpected. Now, in brief, let me introduce to you a heart disease case and how it was cured. The patient was a 35 years old male suffering from vascular heart disease. For 5 years, his sickness deteriorated. He was in the Setagays Government Hospital for treatment.

During those 5 years, he had been in and out of the hospital 5 to 6 times. He had undergone high tech examinations such as angiogram by injecting VINYL via the vein into the heart. He consulted and sought treatment from many good doctors where later he underwent a major surgical operation. Upon his discharge from the hospital, he quit his job to convalesce. However, each time when his illness relapsed, the attack seemed to be even more severe. Last year, in August, his relatives were in despair and expected he would not live much longer. It so happened at that time that the victim’s relative came across ionized water processor. His illness responded well and he is now on the road to recovery.”

Note: In the United States, cardiovascular diseases account for more than one-half of the approximate 2 million deaths occurring each year. It is estimated that optimal conditioning of drinking water could reduce this cardiovascular disease mortality rate by as much as 15 percent in the United States”

Gastric

Prof. Kogure Keizou, Kogure Clinic of Juntendo Hospital, Japan

“The stomach is readily upset both by diseases affecting the stomach and by other general illnesses. In addition, any nervous tension or anxiety frequently causes gastric upset, vague symptoms when they are under some strain.

The important role of ionized water in our stomach is to neutralize the secretion and strengthen it s functions. Usually, after consuming the ionized water for 1 to 3 minutes, the gastric juice increase to 1 1/2 times. For those suffering from hyperchlorhydria or achlorhydria (low in gastric juice) the presence of ionized water will stimulate the stomach cells to secrete more gastric juice. This in turn enhances digestion and absorption of minerals.

However, on the other hand, those with hyperchlorhydria (high in gastric juice), the ionized water neutralizes the excessive gastric juice. Hence, it does not create any adverse reaction.

According to the medical lecturer form Maeba University, the pH of the gastric secretion will still remain normal when ionized water is consumed. This proves that the ability of the ionized water is able to neutralize as well as to stimulate the secretion.”

Kidney Problem

Prof. Kuwata Keijiroo, Doctor of Medicine, Japan

Dr Kerijiroo explains that for severe kidney failure, water intake has to be restricted. However whereas ordinary tap water “contains phosphate, calcium carbonate and the acidic ions…. [that] tend to reduce the efficiency of the calcium ions….” he feels that in controlled amounts, Alkaline Ionic water will “strengthen the heart and increase urination.”

He goes on to claim that over the next six to twelve months, the patient should maintain an alkaline diet (reduced animal protein) and continue drinking the Alkaline Ionic water to reduce the amounts of urea and uric acid in the blood. He also feels that, through his clinical experience that patients undergoing kidney dialysis should also drink Alkaline Ionic water as well as those patients with kidney disease who do not respond to drugs.

Understanding the Science Behind Molecular Hydrogen Water and Alkaline Ionized Water

Why Scientific Research on Water Quality Matters

Water is the single most important nutrient for the human body. Every organ, tissue, and cell relies on water for optimal function. While traditional discussions about water have focused on purity and hydration, modern scientific research is increasingly investigating the role of dissolved molecular hydrogen, oxidation-reduction potential (ORP), mineral composition, and water structure in supporting human wellness.

Over the last two decades, researchers from universities, hospitals, and scientific institutions around the world have published hundreds of peer-reviewed studies investigating molecular hydrogen and alkaline ionized water. These studies explore a broad range of topics including oxidative stress, inflammation, exercise recovery, metabolic health, hydration, neurological wellness, cardiovascular function, gastrointestinal health, and healthy aging.

The growing body of research has positioned molecular hydrogen as one of the most exciting subjects in modern wellness science.

⸻

What Is Molecular Hydrogen?

Molecular hydrogen, represented chemically as H₂, is the smallest and lightest molecule in the universe.

Unlike hydrogen ions (H+) that determine pH levels, molecular hydrogen exists as a neutral gas dissolved in water. Because of its extremely small molecular size, hydrogen can rapidly diffuse throughout the body and potentially reach areas that many larger antioxidant compounds cannot easily access.

Researchers have been particularly interested in molecular hydrogen because it appears to selectively interact with certain reactive oxygen species while preserving beneficial biological signaling molecules.

This unique characteristic has made molecular hydrogen the subject of extensive scientific investigation worldwide.

⸻

The Discovery That Changed Hydrogen Research

A major breakthrough occurred in 2007 when researchers published findings demonstrating that molecular hydrogen could selectively reduce harmful oxidative stress while preserving beneficial physiological functions.

This publication triggered a dramatic increase in hydrogen-related scientific research.

Since then, thousands of scientific papers, reviews, laboratory investigations, animal studies, and human clinical trials have explored the biological effects of molecular hydrogen.

Today, hydrogen research continues to expand across multiple fields including:

• Preventive wellness

• Sports performance

• Metabolic health

• Healthy aging

• Neurological wellness

• Cardiovascular health

• Recovery and rehabilitation

• Cellular protection

⸻

Understanding Oxidative Stress

Oxidative stress occurs when the production of reactive oxygen species exceeds the body’s ability to neutralize them.

Modern lifestyles expose individuals to numerous sources of oxidative stress, including:

• Environmental pollution

• Processed foods

• Mental stress

• Poor sleep

• Smoking

• Alcohol consumption

• Intense physical exercise

• Natural aging processes

Researchers believe that excessive oxidative stress may contribute to cellular damage and reduced physiological efficiency over time.

This is one of the primary reasons molecular hydrogen has become a focus of scientific interest.

⸻

Molecular Hydrogen and Antioxidant Activity

Traditional antioxidants often neutralize reactive oxygen species indiscriminately.

Molecular hydrogen appears to behave differently.

Research suggests that hydrogen may selectively target certain highly reactive oxidants while leaving beneficial signaling molecules intact.

Scientists consider this selectivity particularly important because some reactive oxygen species are necessary for normal cellular communication and immune function.

The ability of molecular hydrogen to support oxidative balance without disrupting normal physiological processes has been widely discussed throughout the scientific literature.

⸻

Molecular Hydrogen and Inflammation Research

Inflammation is a normal biological process that helps the body respond to challenges and maintain tissue repair.

However, chronic low-grade inflammation has become increasingly common in modern populations.

Scientific studies have investigated the relationship between molecular hydrogen and inflammatory pathways.

Researchers have observed that hydrogen may influence various cellular signaling mechanisms involved in inflammatory responses.

This area remains one of the most active fields of hydrogen research and continues to attract attention from medical and scientific communities worldwide.

⸻

Molecular Hydrogen and Exercise Performance

Athletes and fitness enthusiasts are increasingly interested in molecular hydrogen because of its potential role in exercise recovery.

Physical exercise naturally increases oxidative stress due to elevated oxygen consumption.

Studies have examined whether hydrogen-rich water may support:

• Recovery after exercise

• Muscle comfort

• Athletic performance

• Reduced exercise-induced fatigue

• Improved endurance

Although research remains ongoing, many studies have reported promising findings that warrant further investigation.

⸻

Molecular Hydrogen and Metabolic Health

Metabolic wellness plays a critical role in long-term health.

Researchers have explored molecular hydrogen’s potential effects on:

• Blood glucose regulation

• Lipid metabolism

• Cholesterol profiles

• Energy production

• Cellular metabolism

Several clinical studies have reported encouraging observations, making metabolic health one of the most widely researched applications of molecular hydrogen.

⸻

Molecular Hydrogen and Healthy Aging

Aging is associated with increased oxidative stress and reduced cellular efficiency.

Scientists studying longevity and healthy aging have investigated whether molecular hydrogen may help support:

• Cellular protection

• Mitochondrial efficiency

• Energy production

• Cognitive function

• Overall vitality

Although aging is a complex biological process involving numerous factors, hydrogen continues to be studied as a potential supportive wellness tool.

⸻

Molecular Hydrogen and Brain Health

The brain consumes a significant amount of oxygen and is particularly sensitive to oxidative stress.

Because molecular hydrogen is exceptionally small, researchers believe it may cross biological barriers more effectively than many larger compounds.

Scientific investigations have examined potential relationships between hydrogen and:

• Cognitive function

• Mental performance

• Neurological wellness

• Brain cell protection

• Healthy aging of the nervous system

This remains one of the most exciting areas of hydrogen research.

⸻

Understanding Alkaline Ionized Water

Alkaline ionized water is produced through electrolysis, a process that separates incoming water into alkaline and acidic streams.

The alkaline water contains dissolved minerals such as:

• Calcium

• Magnesium

• Potassium

• Sodium

These minerals contribute to the water’s alkalinity and taste profile.

Many users report that alkaline ionized water tastes smoother and easier to drink than ordinary water.

⸻

Hydration and Alkaline Water

Hydration remains one of the most important aspects of human health.

Research has investigated whether alkaline ionized water may influence:

• Water absorption

• Hydration status

• Exercise recovery

• Fluid balance

• Blood viscosity

Several studies have reported improvements in hydration-related markers, particularly following physical activity.

However, hydration ultimately depends on total fluid intake and overall lifestyle habits.

⸻

The Role of Negative ORP

Oxidation Reduction Potential (ORP) is a measure of a substance’s tendency to gain or lose electrons.

Many alkaline ionized waters exhibit negative ORP values.

Researchers have studied ORP as an indicator of electron availability and antioxidant potential.

Although ORP alone does not determine health benefits, it remains an important technical parameter used to evaluate ionized water systems.

⸻

Why Hydrogen Concentration Matters

In modern hydrogen research, one of the most important measurements is dissolved hydrogen concentration.

Hydrogen concentration is generally expressed in:

• Parts Per Billion (PPB)

• Parts Per Million (PPM)

Higher dissolved hydrogen levels allow greater quantities of molecular hydrogen to be delivered through drinking water.

This is why advanced hydrogen water systems are designed to maximize hydrogen concentration while maintaining water quality and stability.

⸻

The Future of Hydrogen Water Research

The scientific understanding of molecular hydrogen continues to evolve rapidly.

Every year, new studies are published exploring the role of hydrogen in:

• Cellular health

• Sports science

• Wellness optimization

• Metabolic support

• Healthy aging

• Recovery science

• Nutritional medicine

As research continues to expand, molecular hydrogen is increasingly recognized as one of the most promising subjects in the field of wellness and preventive health science.
