And as bad as aluminum's may be for us, I can't help but wonder how bad concentrated salts might also be. it's something to consider.

Anyway, I used these mineral salt rocks back in my militant hippy days (about 2 decades ago), and somehow or another I contracted a bizarre fungus in my armpits. I broke down and shaved the hairy beasts, but that alone didn't get rid of it. I began using antrimicrobial soap once in a while and still, no change. As far as I know there was no discernible odor (keep in mind that everyone I hung out with back then doused themselves in patchouli, so who knows if they could smell anything other than that--which smells more like a dirty rodent cage to me than a sweet hippy nowadays). Anyway, the ONLY thing that got rid of it was Arm & Hammer Anti-Perspirant/Deodorant.

I will never go back.

p.s. I was also a vegetarian back then, so the theory that a vegetarian diet will keep such odors, bacteria and fungi at bay is untrue.
