Yes, I mean burned Hg frequency. I don`t know why she felt better on it. she had been crying all day, and suddenly felt better and more balanced. I think she was herxing badly, and I had put too many lyme frequencies on her at once perhaps. Perhaps she also felt bad from the release of mercury. thank`s for the links! I have tried chelating o regular EDTA and felt really bad on it, a few years ago. I never tried home made. She is now thinking of getting the amalgan out of her mouth. So can I use the burned Hg frequency for more than 80 a day?
