The word „chelation“ means „pincers“ in Greek and explains the principle of the chemical effect of a complex which binds metals called „chelating agent“. Chelating agents bind metal ions and are then removed by the organism in a natural way. The chelation therapy is a process of detoxification which is acknowledged as a measure for lead poisoning by the orthodox medicine. But also in the case of many other diseases detoxification and purification of metals in the body play a central role.
One way to think about the chelation process is to compare it to the way we unclog our drains. We add a chemical to our drain. It dissolves the blockage. The resulting compound is removed from the drain using the existing plumbing system. Chelation process works in a similar manner on our body.
