I absolutely agree that exercise mobilizes the mercury. The better question is how to gradually improve the health condition of the lymphatic/immune system.
One thing that I did buy for about $250 was a small trampoline called a rebounder. You can be as agressive or passive as you feel- and do 2 minutes or ten. The principle is that the change in direction should help the one-way valves open so that the crud keeps moving. It does seem to work for me.
I also use the power massage feature on my shower to blast my legs and arms about where I figure the lympth flows.
This is definitely helping the numb joints that I have.

The healthier the immune system is then the more crap the blood vessels can transfer to it. That is what I have read anyway. So it should permit more of the mercury to be dumped with less of a herxheimer effect.

The question is " What products will best assist in improving the health of the immune/ lympth system ?"

Any ideas Russ or anyone else?
