I will try the St John's and continue Lugol rinses. It's kinda funny, the dentist gave me some valium to take before getting the root canal-uh-20 of them! I really expressed my displeasure at the root canal option, so they must have thought I was just a nervous nelly. I asked about extraction, got horrified looks. Even when I told them about Dr. Weston Price's findings and asked if they were familiar with his research....well, I guess the establishment is all the same. They look at you like you have two heads. I am used to that.Thank you all. Looks like it's going to be a long road.I have chelated the mercury and will continue. Unfortunately since I travel to third world countries I have had my share of mercury and toxins injected into me to get into these countries. I am so glad it's finally out of my mouth!
