I took Dr. Natura's Colonix cleanse a few years ago. This was before I realized I had mercury poisoning, so I'm not sure if it's mercury friendly or not. My symptoms weren't nearly as bad back then and my hair wasn't falling out either.

The first time through the cleanse was crazy and I certainly rid my body of parasites. This is the website. http://www.drnatura.com/
I DO NOT recommend clicking on the detox pictures if you get grossed out easily.
