Ionized water treatment for cancer
Ionized water is very alkaline (if your ionizer makes the water alkaline), has a high redox potential (i.e. it is a good antioxidant because its ORP value is very negative), and it has its water molecules in smaller clusters than normal water. All of these things help inhibit the spread of cancer and aid in killing cancer cells, directly or indirectly. However, there is not enough evidence to categorize it as a stand-alone treatment plan.
Ionized water works on cancer in three major ways. Because it is a good antioxidant, meaning it has a very negative ORP value (Oxidation Reduction Potential), it neutralizes free radicals (i.e. ROS – Reactive Oxygen Species), making many oxygen molecules available to the cancer cells; either to slow the growth of cancer or to kill the cancer cells. This is done with the hydroxyl ions in the ionized water.
Unlike hydrogen peroxide, which adds oxygen molecules to the body (i.e. they don't already exist in the body), ionized water makes existing oxygen molecules, already in the body, available to the cancer cells by giving them electrons. This actually has advantages because it removes damaging free radicals at the same time.
Ionized water is also very alkaline. Cancer cells cannot thrive in an alkaline environment:
Dr. Keiichi Morishita in this book, The Hidden Truth of Cancer, states that if the blood develops a more acidic condition, then these excess acidic wastes have to be deposited somewhere in the body. If this unhealthy process continues year after year, these areas steadily increase in acidity, and their cells begin to die.
Other cells in the affected area may survive by becoming abnormal; these are called malignant. Malignant cells do not respond to brain commands. They undergo a cellular division that is out of control. This is called cancer.
Modern medicine in America treats these malignant cells as if they were bacteria or viruses. It uses chemotherapy, radiation, and surgery to treat cancer. Yet none of these treatments will help very much, if after all of that, the acidic environment remains.
Drinking water that has a high alkaline pH, because of its de-acidifying effect, will help in preventing cancer. In Asia, alkaline water is regularly served to patients, and is considered a regular part of treatment.
Water molecules in our body do not individually float around, they exist in clusters of water molecules. Ionized water clusters are significantly smaller than normal water cluster. A water cluster generally consists of about a dozen water molecules. Because the cluster is so big, the water clusters cannot penetrate many places in your body. By making clusters half that size, in terms of the number of water molecules per cluster, the clusters (i.e. the water) can penetrate into more places in the body. The shape of ionized water clusters (a hexagon) also helps them get into places regular water cannot go. These things are called making “wetter water.”
In addition to these things, ionized water removes a lot of toxic waste products from the body. In fact there are many other benefits to drinking ionized water, most of which have nothing to do with cancer.
I suspect that virtually all brands of water ionizers are made in Japan or Korea, or the parts are made in Japan or Korea and they are assembled in the U.S. Japan and Korea are where most of the research is taking place.
