It was for the electrolyte. My brother has a heart condition and when his K levels drop he needs this, so it came to mind. There have been some other postings on this recently.

As for the Hankies and T-Shirts - I was thinking multiple use and in a jiffy, a brand NEW chlorine-washed, plastic-packed shirt could be cut into a fairly sterile dressing. And it could be packed somplace other than the FAK - I probably didn't mention that part, and it may not make sense when carrying something this complete. Good point about the antiseptic on an fresh wound requiring multiple dressings.
