Bal In Oil is used to treat acute poisoning from heavy metals including arsenic, gold, mercury, and lead. It may also be used for certain cases of Wilson's disease and has applications in radiation exposure scenarios involving internal contamination.
As a chelating agent, dimercaprol binds to heavy metal ions in the bloodstream and tissues through its sulfhydryl groups, forming stable, water-soluble compounds that are then excreted by the kidneys. This process helps reduce the toxic effects of accumulated metals in vital organs.
