Welcome to the wonderful world of micro-clustered ionized, energized, pH alkaline, oxygenated, anti-oxidant and mineralized Miracle Water, produced by the "E-Cosway Hexagon Water Purification System: http://www.shop.lovingtolearn.biz (Donation: $500) To understand the properties, concepts and benefits necessary for you to appreciate Hexagon Water, here's a simplified explanation of a few of the terms...

"WATER: THE CHEMISTRY OF LIFE"

Whenever we attempt to determine whether there is life as we know it on Mars or other planets, scientists first seek to establish whether or not water is present. Why? Because life on earth totally depends on water.

A high percentage of living things, both plant and animal are found in water. The bodies of all living organisms are composed largely of water. About 70 to 90 percent of all organic matter is water.

The chemical reactions in all plants and animals that support life take place in a water medium. Water not only provides the medium to make these life sustaining reactions possible, but water itself is often an important reactant or product of these reactions. In short, the chemistry of life is water chemistry.

WATER: The Universal Solvent

Water is a universal, superb solvent due to the marked polarity of the water molecule and its tendency to form hydrogen bonds with other molecules. One water molecule, expressed with the chemical symbol H2O, consists of 2 hydrogen atoms and 1 oxygen atom.

Polarity of Water Molecules

In a water molecule, two hydrogen atoms are covalently bonded to the oxygen atom. This means that although the water molecule as a whole is stable, the greater mass of the oxygen nucleus tends to draw in all the electrons in the molecule including the shared hydrogen electrons giving the oxygen portion of the molecule a slight electronegative charge.

Looking at molecules like NaCl better known table salt in water, this is why we call water the universal solvent. Salt is granular and hard, but in water it dissolves or the molecules are broken or separated from each other. Water is a natural solution that breaks or dissolves the bonds of larger, more complex molecules. This is the chemistry of life on earth, in water and on land.

OXIDATION (Redox)

Basically, reduction means the addition of an electron (e-), and its converse, oxidation means the removal of an electron.

When molecules A and B come into contact, here is what happens:

B grabs an electron from molecule A. Molecule A has been oxidized because it has lost an electron. The net charge of B has been reduced because it has gained a negative electron (e-). In biological systems, removal or addition of an electron constitutes the most frequent mechanism of oxidation-reduction reactions. These oxidation-reduction reactions are frequently called redox reactions.

The addition of an electron, reduction, stores energy in the reduced compound. The removal of an electron, oxidation, liberates energy from the oxidized compound. Whenever one substance is reduced, another is oxidized.

pH ALKALINE

An acid is a substance that increases the concentration of hydrogen ions (H+) in water. A base is a substance that decreases the concentration of hydrogen ions, in other words, increasing the concentration of hydroxide ions OH-.

The degree of acidity or alkalinity of a solution is measured in terms of a value known as pH.

What is pH?

On the pH scale, which ranges from 0 on the acidic end to 14 on the alkaline end, a solution is neutral if its pH is 7. At pH 7, water contains equal concentrations of H+ and OH- ions. Substances with a pH less than 7 are acidic because they contain a higher concentration of H+ ions. Substances with a pH higher than 7 are alkaline because they contain a higher concentration of OH- than H+. The pH scale is a log scale so a change of one pH unit means a tenfold change in the concentration of hydrogen ions.

Importance of Balancing pH

Living things are extremely sensitive to pH and function best (with certain exceptions, such as certain portions of the digestive tract) when solutions are nearly neutral. Most interior living matter (excluding the cell nucleus) has a pH of about 6.8.

Blood plasma and other fluids that surround the cells in the body have a pH of 7.2 to 7.3. Numerous special mechanisms aid in stabilizing these fluids so that cells will not be subject to appreciable fluctuations in pH. Substances which serve as mechanisms to stabilize pH are called buffers. Buffers have the capacity to bond ions and remove them from solution whenever their concentration begins to rise. Conversely, buffers can release ions whenever their concentration begins to fall. Buffers thus help to minimize the fluctuations in pH. This is an important function because many biochemical reactions normally occurring in living organisms either release or use up ions.

OXYGEN and Free Radicals: Too Much of a Good Thing?

Oxygen is essential to survival. It is relatively stable in the air, but when too much is absorbed into the body it can become active and unstable and has a tendency to attach itself to any biological molecule, including molecules of healthy cells. The chemical activity of these free radicals is due to one or more pairs of unpaired electrons. About 2% of the oxygen we normally breathe becomes active oxygen, and this amount increases to approximately 20% with aerobic exercise.

Such free radicals with unpaired electrons are unstable and have a high oxidation potential, which means they are capable of stealing electrons from other cells. This chemical mechanism is very useful in disinfectants such as hydrogen peroxide and ozone which can be used to sterilize wounds or medical instruments. Inside the body these free radicals are of great benefit due to their ability to attack and eliminate bacteria, viruses and other waste products.

Active Oxygen in the Body

Problems arise, however, when too many of these free radicals are turned loose in the body where they can also damage normal tissue. Putrefaction sets in when microbes in the air invade the proteins, peptides, and amino acids of eggs, fish and meat. The result is an array of unpleasant substances such as: Hydrogen sulfide, Ammonia, Histamines, Indoles, Phenols, Scatoles

These substances are also produced naturally in the digestive tract when we digest food, resulting in the unpleasant odor evidenced in feces. Putrefaction of spoiled food is caused by microbes in the air; this natural process is duplicated in the digestive tract by intestinal microbes. All these waste products of digestion are pathogenic, that is, they can cause disease in the body.

Hydrogen sulfide and ammonia are tissue toxins that can damage the liver. Histamines contribute to allergic disorders such as atopic dermatitis, urticaria (hives) and asthma. Indoles and phenols are considered carcinogenic. Because waste products such as hydrogen sulfide, ammonia, histamines, phenols and indoles are toxic, the body's defense mechanisms try to eliminate them by releasing neutrophils (a type of leukocyte, or white corpuscle). These neutrophils produce active oxygen, oddball oxygen molecules that are capable of scavenging disintegrating tissues by gathering electrons from the molecules of toxic cells.

Problems arise, however, when too many of these active oxygen molecules, or free radicals, are produced in the body. They are extremely reactive and can also attach themselves to normal, healthy cells and damage them genetically. These active oxygen radicals steal electrons from normal, healthy biological molecules. This electron theft by active oxygen oxidizes tissue and can cause disease.

Effect of Oxidation on Vital Organs Oxidated Tissue Leads to:

Liver - Hepatitis, cirrhosis, cancer
Pancreas - Pancreatitis, diabetes, cancer
Kidney - Nephritis, nephrosis, cancer

Because active oxygen can damage normal tissue, it is essential to scavenge this active oxygen from the body before it can cause disintegration of healthy tissue. If we can find an effective method to block the oxidation of healthy tissue by active oxygen, then we can attempt to prevent disease.

Hydrogen sulfide, amonia, histamines, indoles, phenoles, and scatoles present in the digestive tract of the human body.

In order to protect the body from damage by hydrogen sulfide, amonia, histamines, indoels, phenoles and scatoles, neutrophils (leukocytes) produce active oxygen to oxidize these waste products.

ANTIOXIDANTS

One way to protect healthy tissue from the ravages of oxidation caused by active oxygen is to provide free electrons to active oxygen radicals, thus neutralizing their high oxidation potential and preventing them from reacting with healthy tissue.

Research on the link between diet and cancer is far from complete, but some evidence indicates that what we eat may affect our susceptibility to cancer. Some foods seem to help defend against cancer, others appear to promote it.

Much of the damage caused by carcinogenic substances in food may come about because of an oxidation reaction in the cell. In this process, an oddball oxygen molecule may damage the genetic code of the cell. Some researchers believe that substances that prevent oxidation -- called ANTIOXIDANTS -- can block the damage.

This leads naturally to the theory that the intake of natural antioxidants could be an important aspect of the body's defense against cancer. Substances that some believe inhibit cancer include vitamin C, vitamin E, beta-carotene, selenium, and gluthione (an amino acid). These substances are reducing agents. They supply electrons to free radicals and block the interaction of the free radical with normal tissue.

How We Can Avoid Illness?

As we mentioned earlier, the presence of toxic waste products such as hydrogen sulfide, ammonia, histamines, indoles, phenols and scatoles impart an offensive odor to human feces. In the medical profession, it is well known that patients suffering from hepatitis and cirrhosis pass particularly odoriferous stools. Putrefaction sets in when microbes in the air invade the proteins, peptides, and amino acids of eggs, fish and meat. The result is an array of unpleasant substances.

Active Oxygen in the Body

There is no substitute for a healthy balanced diet, especially rich in antioxidant materials such as vitamin C, vitamin E, beta-carotene, and other foods that are good for us. However, these substances are not the best source of free electrons that can block the oxidation of healthy tissue by active oxygen.

Water treated by electrolysis to increase its reduction potential is the best solution to the problem of providing a safe source of free electrons to block the oxidation of normal tissue by free oxygen radicals. We believe that reduced water, water with an excess of free electrons to donate to active oxygen, is the best, because the molecule weight of reduced water is low, making it fast acting and able to reach all tissues of the body in a very short time.

Ionized water is the product of mild electrolysis which takes place in the ionized water unit. Ionized water is treated tap water that has not only been filtered, but has also been reformed in that it provides reduced water with a large mass of electrons that can be donated to active oxygen in the body to block the oxidation of normal cells.

THE IONIZED WATER UNIT

Redux Potential

Normal tap water, for example, with a pH of 7 is approximately neutral on the pH scale of 0 to 14. When measured with an ORP (oxidation potential) meter its redox potential is approximately +400 to +500 mV. Because it has a positive redox potential, it is apt to acquire electrons and oxidize other molecules. Reduced Ionized Water, on the other hand, has a negative redox potential of approximately -250 to -350 mV. This means it has a large mass of electrons ready to donate to electron-thieving active oxygen.

How an IONIZED WATER Unit works

The Ionized Water unit, slightly taller and thicker than a large dictionary on end, is an electrical appliance connected to your kitchen water supply to perform electrolysis on tap water before you drink it or use it in the kitchen for cooking or cleaning.

A special attachment re-directs tap water out of the faucet through a plastic hose into the Ionized Water unit. Inside the Ionized Water unit, the water is first filtered through activated charcoal. Next, the filtered water passes into an electrolysis chamber equipped with a platinum-coated titanium electrode where electrolysis takes place.

Cations, positive ions, gather at the negative electrodes to create cathodic water (reduced water). Anions, negatively charged ions, gather at the positive electrode to make anodic water (oxidized water). Through electrolysis, reduced water not only gains an excess amount of electrons (e-), but the cluster of H 2O seem to be reduced in size from about 10 to 13 molecules per cluster to 5 to 6 molecules per cluster.

The reduced water comes out of the faucet, and the oxidized water comes out of a separate hose leading into the sink. You can use the reduced water for drinking or cooking. The oxidation potential of the oxidized water makes it a good sterilizing agent, ideal for washing hands, cleaning food or kitchen utensils, and treating minor wounds.



What the IONIZED WATER Unit Produces

Redox Potential Comparison

After electrolysis of the water inside the Ionized Water unit, reduced water comes out of the cathodic side and oxidized water comes out of the anodic side. Compare these measurements of these three types of water: tap water before electrolysis, the reduced water, and the oxidized water.

Reduction-Oxidation (Redux) Potential

Water Type - Leads to: - pH - What it Means

Tap Water - +400 to +500mV - 7 - Slight oxidation potential

Reduced Water - -250 to -350mV - 8 - Strong reduction potential: More electrons donated to free radicals.

Oxidated Water - +700 to +800mV - 4 - Strong oxidation potential: Less electrons oxidizing and sterilizing.

OXIDATIVE POTENTIAL

Redox Potential, not pH, is the Crucial Factor

Traditionally we have judged the properties of water from the standpoint of pH, in other words whether water is acidic or alkaline. According to Dr. Yoshiaki Matsuo PhD., the inventor of the Ionized Water unit, "In my opinion, redox potential is more important than pH. The importance of pH is over emphasized. For example, the average pH of blood is 7.4 and acidosis or alkalosis are defined according to deviation within the range of 7.4 +- 0.005. But nothing has been discussed about ORP, or oxidation-reduction potential."

The pH of tap water is about pH 7, or neutral. When tap water is electrolyzed into Ionized Water, its reduced water has a pH of about 9 and the oxidized water a pH of about 4. Even if you make alkaline water of pH 9 by adding sodium hydroxide or make acidic water of pH 3 by adding hydrogen chloride, you will find very little change in the ORP values of the two waters. On the other hand, when you divide tap water with electrolysis you can see the ORP fluctuate by as much as +- 1,000 mV. By electrolysis we can obtain reduced water with negative potential that is good for the body.

USING IONIZED WATER

What IONIZED WATER Does

The Ionized Water unit produces two kinds of water with different redox potentials, one with a high reduction potential and the other with a high oxidation potential.

Reduced Water

When taken internally, the reduced Ionized Water with its redox potential of -250 to -350 mV readily donates its electrons to oddball oxygen radicals and blocks the interaction of the active oxygen with normal molecules. A biological molecule (BM) remains intact and undamaged.

Undamaged biological molecules are less susceptible to infection and disease. Ionized Water gives up an extra electron and reduces the active oxygen (AO), thus rendering it harmless. The AO is reduced without damaging surrounding biological molecules. Substances which have the ability to counteract active oxygen by supplying electrons are called scavengers. Reduced water, therefore, can be called scavenging water.

When taken internally, the effects of reduced water are immediate. Ionized Water inhibits excessive fermentation in the digestive tract by reducing indirectly metabolites such as hydrogen sulfide, ammonia, histamines, indoles, phenols and scatoles, resulting in a cleaner stool within days after reduced water is taken on a regular basis. In 1965, the Ministry of Welfare of Japan announced that reduced water obtained from electrolysis can prevent abnormal fermentation of intestinal microbes.

Oxidized Water

Oxidized water with its redox potential of +700 to +800 mV is an oxidizing agent that can withdraw electrons from bacteria and kill them. The oxidized water from the Ionized Water unit can be used to clean hands, kitchen utensils, fresh vegetables and fruits, and to sterilize cutting boards and minor wounds. Tests have shown that oxidized water can be used effectively to treat athlete's foot, minor burns, insect bites, scratches, and so on.

Dr. Yoshiaki Matsuo, Vice Director of the Water Institute of Japan, has developed another apparatus capable of producing hyperoxidized water with a redox potential of +1,050 mV or more, and a pH lower than 2.7. Tests have shown that this hyper oxidized water can quickly destroy MRSA (Methecillin Resistant Staphylococcus Aureus).

Although hyperoxidized water is a powerful sterilizing agent, it won't harm the skin. In fact, it can be used to heal. Hyperoxidized water has proven effective in Japanese hospitals in the treatment of bedsores and operative wounds with complicated infections.

But perhaps the most exciting future application of hyperoxidized water is in the field of agriculture where it has been used effectively on plants to kill fungi and other plant diseases. Hyperoxidized water is non-toxic, so agricultural workers can apply it without wearing special protective equipment because there is no danger of skin or respiratory damage. An added benefit of using hyperoxidized water to spray plants is that there is no danger to the environment caused by the accumulation of toxic chemicals in the ground.

Ionized Water Superior to Antioxidant Diet

Today we read much about correct dieting principles and paying attention to what we eat in order to stay healthy. This is a sensible practice, but it is surprising that many of us don't realize that the bulk of what eat is composed of water. Vegetables and fruits are 90% water; fish and meat are about 70% water as well.

Even advocates of the importance of vitamin C in diet staples have to admit that its potency, namely, the redox potential of this important vitamin, rapidly diminishes with age and preparation for the dining table. Carbohydrates, the main consistent of vegetables and fruit, has a molecular weight of 180 whereas water has a much lower molecular weight of 18.

Ionized Water, with its low molecular weight and high reduction potential, makes it a superior scavenging agent of active oxygen. But electrolysis inside the Ionized Water unit not only charges the reduced water with electrons, it also reduces the size of reduced water molecule clusters.

NMR (Nuclear Magnetic Resonance) analysis reveals that tap water and well water consists of clusters of 10 to 13 H2 0 molecules. Electrolysis of water in the Ionized Water unit reduces these clusters to about half their normal size -- 5 to 6 water molecules per cluster.

Reduction-Oxidation (Redux) Potential

Substances Leads to:

Tap Water 18
Beta-carotene 150
Vitamin E 153
Vitamin C 176

As the graph above shows, the NMR signal that measures cluster size by line width at half-amplitude shows 65 Hz for reduced water and 133 Hz for tap water, revealing that the reduced water clusters are approximately half the size of tap water clusters.

 

This is why Ionized Water is more readily absorbed by the body than untreated tap water. Ionized Water quickly permeates the body and blocks the oxidation of biological molecules by donating its abundant electrons to active oxygen, enabling biological molecules to replace themselves naturally without damage caused by oxidation that can cause diseases.

SUMMARY AND CONCLUSIONS

Upstream and Downstream Theory: Prevent Disease at the Source

According to Dr. Hidemitsu Hayashi, Director of the Water Institute of Japan, "To eliminate the pollutants in a large stream that is contaminated at its source, we must work on the problems upstream at the headwaters -- the source of the pollution -- not downstream where we can only try to treat the evidence of damage caused by the pollution. Ionized Water's contribution to preventive medicine is essentially upstream treatment."

Upstream

According to our model, we consider the digestive tract upstream where we intake water and food. Although many people today in developed countries are growing more skeptical about what they eat, they tend to concentrate more on what the food contains rather than the metabolized products of foods in the digestive tract. Reduced water indirectly reduces hydrogen sulfide, ammonia, histamines, indoles, phenoles, and scatoles and changes them into harmless substances

Defacation of Cleaner Stools.

For example, consider the typical balanced diet of meat and vegetables. Meat protein is metabolized into amines while nitrates from fertilizers used to grow vegetables metabolize into nitrites in the digestive tract. These amines and nitrites combine to form nitrosamine, a recognized carcinogen.

We've already discussed that odoriferous feces are evidence of excessive fermentation in the digestive tract, so reduced water performs a very important function upstream in the digestive tract by reducing this excessive fermentation as evidenced by cleaner stools within days of starting a steady regimen of reduced water.

Downstream

Reduced water indirectly reduces hydrogen sulfide, ammonia, histamines, indoles, phenoles, and scatoles and changes them into harmless substances

Defacation of Cleaner Stools.

Downstream from the digestive tract, starting at the liver, reduced water quickly enters the liver and other organs due to, first, its lower molecular weight, and, secondly, the size of its clusters. At tissue sites throughout the body, reduced water with its safe, yet potent reduction potential readily donates its passenger electrons freely to active oxygen and neutralizes them so they cannot damage the molecules of healthy cells. Normal cells are protected from the electron thievery of active oxygen and allowed to grow, mature, function and regenerate without interference from rogue, oddball oxygen radicals which tend to steal the electrons from the molecules of normal, healthy biological molecules.

The Water Boom

We are now in the midst of a water boom. In Japan and other countries consumers are buying various kinds of bottled and canned water even though water is one of our most abundant vital resources. Research data reveals that mineral waters have an ORP of +200 mV, slightly lower than the +400 mV measured for ordinary tap water. We can say that at least mineral water is marginally better than tap water from the viewpoint of ORP. Compared to any processed water for sale, however, Ionized Water with its reduction potential of -250 to -300 mV is beyond comparison due to its ability to scavenge active oxygen radicals.

 

Filtration

Virtually all water ionizers contain some type of internal filtration. This filter is the industry leader and helps significantly reduce contamination in your water, there are a few contaminant-specific situations where some customers may wish to add other optional treatment techniques to improve the filtration. Your water experts have created a line of water filtration products that address the most common problems found across the US. Using proven, traditional treatment techniques, we have specific products available for removal/reduction each of the following contaminants:

Arsenic/Lead/Fluoride
Chloramines
Heavy Metals
Hydrogen Sulfide
Nitrates
Iron
E-Coli and Cyst
Reverse Osmosis
Virtually all known contaiminants (Reverse Osmosis with a remineralization cartridge)

Re-mineralizer Catridge

Capacity: Up to 1,000 gallons

Intended for use outside of your IonWays water ionizer machine.

In areas where there are low levels of naturally occurring minerals, or after a reverse osmosis system, extra minerals and trace elements are needed. The water experts at IonWays have created systems and products to take advantage of the best of R/O - contaminant free water - by installing it as a pre-filter before the ionizer.

To make it possible to ionize "pure" water, IonWays has perfected re-mineralization technologies to add a healthy blend of inorganic and organic forms of calcium, magnesium and 70+ organic trace elements to the water before ionization. Our unique re-mineralizer is a proprietary blend of organic and inorganic minerals that also provides over 70 trace elements.

A partial list of minerals/trace elements in the organic mineral source are:

Beryllium Calcium Carbon Cerium Cesium
Germanium Holmium Magnesium Molybedium Neodymium
Niobium Osmium Palladium Potassium Praseodymium
Rhenium Rhodium Rubidium Ruthenium Samarium
Scandium Sodium Stronium Tantalum Tellurium
Terbium Thallium Vanadium Yttrium Zirconium
