as a kid, my mom used bentonite clay on EVERYTHING... bug bite? clay pack. poisen ivy? clay pack. zit? clay pack. motercycle burn (that was bad), clay pack. i spent half my childhood packed in clay,
.
and it really did work, it's amazing for drawing out infection and anything else (like poison) that needs to be drawn out. i think i even remember drinking it a few times for stomach bugs.
((((kym)))) i'm so glad ds is ok! how scary!
