Chelation

The term "chelation" refers to the action of medicines that enter the body and actively seek to attach themselves to metal ions and then escort the metals out of the body, generally through the kidneys or liver. The word derives from the Greek word for "crab claw." EDTA is a chelator that is available in every emergency room to treat lead poisoning.

Chelation is poorly understood in the medical world in general. This is in some part due to bias and lack of knowledge, but it is also due to the fact that toxic metals do not cause a uniform set of symptoms from one patient to another. For example, one person may have significant fatigue and headaches from the mercury from three fillings in the mouth; another may have 15 fillings and a higher measurable amount of mercury in the urine, yet no symptoms at all; a third may have the same measured amount of mercury, but a completely different set of symptoms from the first person. This makes metal toxicity harder to diagnose than other diseases.

Metal toxicity is common in our modern world. The most common toxic metal is mercury, due to the use of this metal in dental silver fillings (which are 50% mercury by weight) and in vaccines as the preservative thimerosal (since 1999 it’s being replaced with other preservatives). Other frequently elevated toxic metals are lead, nickel, aluminum, cadmium, tin and others.

The simple problem with metals is that they are charged. This means that they drop off electrons and carry a positive charge, sticking to anything they find in the body that has a negative charge. The body much prefers things to have a neutral or very mild charge, so they can be moved around and function normally. Toxic metals bind in damaging ways to destroy mitochondria (the cell’s energy generator), impair nerve growth, disrupt enzyme systems, push iron out of blood cells, decrease immune function and pile up in residual deposits in cells. How sensitive a person is to metal toxicity depends on the particular metal involved, the quantity and distribution of the metal in the tissues, and the person’s degree of inherited ability to clear the metal out on their own.

The terrible epidemic of autism is connected to the use of mercury preservative in vaccines. Autism is a neurologically devastating disease, and it is more than 80 times more common today than it was in 1980. It starts in little children usually, and affects boys much more often than girls. Conventional medical practitioners have no explanation for the epidemic, and have spent most of their effort on poorly-constructed studies aimed at disproving a connection between autism and vaccination. This is terribly irresponsible and unprofessional, given the magnitude of the problem and the abundance of observed cases of autism beginning shortly after vaccination.

Determining whether a patient has metal toxicity is done through the patient’s history of exposure to metals and their symptoms. Provocative testing is also employed, a method of giving the patient intravenous chelating medicine and then measuring how much metal is expressed in the urine to estimate the metal load in the patient. Chelating medicines are chosen based on the results of these evaluations.
