Nat Phos is a cell salt and should be added to taking Manna.
I have to get this book because although I think I understand, I can see I don't really get it. I am only skimming the surface of this and know that it is crucial to learn. my mind is too slow right now but I will get some Nat Phos. I haven't gotten the gold leaf, waiting till i can, but that and yogurt maker on my wish list.
