if you are hg toxic try DMSA. If that doesn't do it try ALA. If that still doesn't do it you are not toxic or there is a hidden source of exposure.

RE jammes
But the problem is I'm afraid there is no such medicine sold in China,like DMSA,ALA. Most of the people in China ,which got prombles caused by Amalgam Fillings,only know they got health prombles, but they don't know what is the problem,they don't know the truth.
