Here is a recipe for mercury chelation that was sent to me by a lady in Kennewick Washington. It appears to work for other metals also. Alpha lipoic acid can also be considered for mercury and other heavy metals chelation.

This is from an article found in the newsletter  "Alternative"
dated June, 1998.  A Dr. Yoshiaki Omura discovered
almost by accident that the leaves of the coriander plant can
accelerate the excretion of mercury, lead and aluminum from the
body.  He performed a study in which three amalgam fillings were
removed from an individual using all the precautions available to
prevent absorption of the mercury from the amalgam. Significant
amounts were later found in the individual's lungs, kidneys,
endocrine organs, liver and heart.  There was no mercury in these
tissues prior to the amalgam removal.

Remarkably, without the help of any chelation agents, cilantro
was able to remove the mercury in two to three weeks.  (Acupunct

Recipe for Cilantro Pesto (Make that "Chelation Pesto")

1 Clove garlic
1/2 cup almonds, cashews, or other nuts
1 cup packed fresh cilantro leaves
2 tablespoons lemon juice
6 tablespoons olive oil

Put the cilantro and olive oil in blender and process until the
cilantro is chopped.  Add the rest of the ingredients and process
to a lumpy paste. (You may need to add a touch of hot water and
scrape the sides of the blender.)  You can change the consistency
by altering the amount of olive oil and lemon juice, but keep the
3:1 ratio of oil to juice.  (It freezes well, so you can make
several batches at once.

He recommends a couple of teaspoons a day for two to three weeks
once or twice a year.
