Chelation is a medical procedure that involves the use of chelating agents to remove heavy metals or other toxic substances from the body. The term "chelation" comes from the Greek word "chele," which means claw, as these agents bind to the harmful substances and form a complex that can be excreted through urine or feces.

Chelation therapy is commonly used to treat heavy metal poisoning, such as lead, mercury, or arsenic poisoning. It works by administering chelating agents either orally or intravenously, which then circulate in the bloodstream and bind to the toxic metals present in the body. The resulting complex is then eliminated through normal bodily processes.

In addition to treating heavy metal toxicity, chelation therapy has also been explored as an alternative treatment for certain medical conditions like atherosclerosis (hardening of arteries) and coronary artery disease. Some studies suggest that chelation therapy may help remove calcium deposits from arteries and improve blood flow.

It's important to note that chelation therapy should always be administered under medical supervision, as it can have potential side effects and risks if not properly monitored. It is crucial to consult with a healthcare professional before considering any form of chelation therapy.

Overall, chelation is a specialized medical procedure aimed at removing toxic substances from the body using specific chelating agents. Its applications range from treating heavy metal poisoning to exploring potential benefits in certain health conditions.
