I agree, I sent her a note because she states - Diarrhea will occur as your body sheds itself of the pathogens. High levels of vitamin C create diarrhea & it takes the body awhile to build up to high dosages (aka bowel tolerance). I don't know if this same reaction happens with Ester-C but I do know it happens with ascorbic acid.
As far as the salt goes, this is in line with the Salt Water Flush that was recommended on this forum a few months ago. 1Tb salt = 15 grams + 2 qts water + juice of one lemon - drank in 1 hour at 7am.
