pawel110,
I am not overly familiar with the methods other than fasting for the removal of heavy metals from the body, but I do know that mercury tends to accumulate in the kidneys & the Brain. I am also not aware either of any literature by the early hygienists that specifically target their removal.
What I do know is that the food Chlorella is an important part of the detoxification program of heavy metals, as approximately 90% of the mercury in our bodies is eliminated through the stools.
These are probably the best guidelines I can find on the subject..................
I also wouldn't commence a fast until after this programme of heavy metal removal has been carried out, and where the fast would then be able to eradicate any leftovers.
