I think it may be helpful to you to check out the use of Cilantro for amalgam detox. There are some pretty good Cilantro pesto recipes around, and maybe she can get into Cilantro Salsas. The fresh herb is also great in sandwiches.. Or rolled into Romaine leaves with the dressing of your choice..
I'll bet you also know about oil pulling already but here's a reminder of it, also Sun Chlorella (20 smackers per box is a lot, but it works better than anything else I've found except for fresh-juiced Wheatgrass).
Lastly, I'm thinking hot/cold footbaths with Energized Water (Made in Stainless Steel, the way I do) with ES, 1/2 teaspoon of Celtic Sea Salt,Baking Soda, Cayenne and Energized Water (maybe H2O2 also, but I haven't done it with that yet) is likely to be a very cost-effective substitute for the Ionizing $40. footbaths.
Oh, one more thing. There are also some detoxing footpads, one of the good brand names is apparently Detoku, which sound like they also would probably be good for her, they work over a period of hours, overnight or whatever. There has been lots of discussion of these on one of the curezone forums. Unfortunately I do not remember which one. I would do a search of CZ with the term "footpads" to find the discussions.
I hope you will stick with footbaths, but of course, the lady will make her own choices. I can only tell you that if I had stayed done that instead of
whole-body baths for awhile, correcting things would have been much easier for me, and taken a lot less time, too..
Hope some of this is helpful, please post back on her progress..
