DMPS (Sodium 2,3-dimercaptopropane-l-sulfonate) is a sulfonic acid salt with free SH-groups that forms complexes with heavy metals such as mercury, cadmium, arsenic, lead, copper, silver, tin, and others. This agent was first developed in China, was then introduced in Russia (used for workers injured by exposure to heavy metals) , and went from there to West Germany. Professor Max Daunderer, M.D., in Munich published a number of papers on the use of DMPS1,2. He found that DMPS is the ideal agent to detox patients who have suffered from amalgam toxicity after the fillings have been removed. Intravenous DMPS leads to dumping of large amounts of heavy metals through the kidneys. 50% are excreted during the six hours following the shot, 90% after 24 hours. Oral DMPS leads to excretion of heavy metals mostly via the stool, but has been in our experience much less effective. DMPS has been proven to be the ideal agent to "clean" the kidneys of heavy metal residues and improve kidney function in patients who have been exposed to heavy metals3,4,5,6,7,8,9,10,11,12,13,14 .
