so, yesterday my roommate lesley went to japantown and randomly found some japanese versions of this product, so we gave them a whirl... i slept with them on my feet last night. when i put the little pads on my feet they were white, when i woke up this morning... they were brown, kind of like a small dirty diaper. and i think it sucked out some blood!!
here's what it looked like in the morning:
do i feel rejuvenated? not really... but my feet feel a little funny, and i have a really stiff neck (i doubt there's a connection)... our theory is that whatever is in the little packet just turns brown from mixing with foot-sweat... i can't imagine it actually sucking harmful toxins from your entire body through the soles of your feet...
