I'd be careful with the potassium chloride if she suspects circulation problems, naturalnews say "Chloride also constricts blood vessels, and narrows blood vessels reduce circulation" http://www.naturalnews.com/Report_acid_alkaline_pH_2.html
I have also experimented with potassium chloride a fair bit for the last 6 months, both as a bromide flush and also to increase my potassium intake, my experience seems to back up what naturalnews say as if i take too much it can give me pins and needles quite bad and also I seem to get more cramps where normally I don't suffer from them.
