Dear Sara,

Just off the top of my head, as Podo. would have been my first guess, Natrum Sulph. is part of a small rubric: Rectum, diarrhea, amel., which is peculiar, so it's an important rubric. I believe the Nat-sulph color is yellow. Phos-ac. is in that rubric, and the desire for ice would support that.

Well there's 2 ideas for you, and I welcome others, as I'm sure you do too.
