I certainly think any amount of mercury is bad -- a few years ago I had all (2) my old amalgam fillings removed. Afterwards a number of weird symptoms (mainly unexplained fatigue) disappeared after a while. I was very careful and even juice fasted (fresh organic vegetable and fruit juices) for a few days, and was looking for all sort of environmental and dietary factors because I just felt like I was drugged half the time. At that time my fillings had just become 20 years old, and the same dentist (who doesn't believe in mercury problems) replaced them since they were old - with gold inlay after I explained my concerns. He wasn't particularly careful about removal of the old stuff, but I didn't care because I figured my body would get rid of any toxic stuff by itself after a while. I'll try find the articles I have on it to pass on if you like- I AM convinced of its toxicity. > Are you convinced that mercury really poses a significant hazard?

BTW in TCM the herbal materia medica says seaweed in moderate amounts (as food and soups from it) are supposed to assist in safe detoxification of heavy toxins. But I know that (1) some people are allergic to it and/or (2) too quick a detox process (body releasing toxins more quickly than they can be transported out) means lots of discomfort. regards Roberta [log in to unmask]
