I have mercury and heavy metal poisoning too. I have been doing magnectic water baths, clay foot baths and detox pads on the feet at night. I do the water bath every two weeks, the clay every month or so and the detox pads about 5 nights a week for the last month. I feel alot better, but I am also doing a parasite cleanse and liver flushing, so don't know what to credit, or is it just taking control of my health that I am feeling so much better. I hope you find the information on the net to help him get better. Look at the relfe.com site regarding pascalite clay. There is information there on mercury too. Good luck to you.
