The word chelate is derived from the Greek word chele, which refers to the claw of a crab or lobster, implying a strong binding action by the chelating agent to another compound. Chelation therapy involves administering specific agents (orally or intravenously) to bind toxic compounds in the blood or tissues of the body.
Toxins have been implicated in the development of many health conditions – everything from hormonal imbalances, to autoimmune disease to diseases of aging such as dementia and cardiovascular disease. When toxic compounds accumulate in the body – due to excessive exposure or a defect in the body’s ability to metabolize and/or eliminate toxins – many normal cellular functions can be disrupted. Some toxins (such as heavy metals) have the ability to displace nutrients and block enzymatic reactions that are essential to health. The result is dysfunction that can occur in the organ or tissue where the toxins accumulate eventually leading to some form of disease.
Toxic metals – such as lead, mercury, arsenic, cadmium and aluminum are the most damaging of toxic compounds. Biologically, some toxic metals have a strong binding affinity for chemical bonds at the level of our DNA and can in fact be mutagenic (causing DNA damage) in certain biological environments, thereby raising the risk of cancer and other chronic disease. Others disrupt hormone, immune or neurological function, contributing to disease in those systems.
The process of removing toxic metals is known as Chelation Therapy. Chelation therapy is most effective when administered by the intravenous route. The origin of chelation therapy dates back to 1940, when it was first used to treat lead poisoning using a chelating agent known as EDTA. Later, it became evident that EDTA chelation therapy plays a significant role in reversing the mechanisms that promote atherosclerotic plaque formations (diseased arteries), which subsequently cause heart disease and peripheral vascular diseases.
Today, EDTA chelation therapy is administered safely by intravenous methods to help prevent and treat cardiovascular disease (heart disease and other venous or arterial disorders) and cerebrovascular disease (such as stroke and vascular dementia).
Other chelating agents, such as DMPS, bind toxic metals such as mercury, arsenic, cadmium, aluminum and lead. Each chelating agent has beneficial application depending on the condition to be treated and how it is administered. Vitamin C, glutathione, chlorella and cilantro also have chelating ability, although significantly weaker than DMPS and EDTA. One or more chelating agents (IV and oral) may be used in combination to achieve the desired outcome.
