ok the explanation is that i was duped by the tv commercials for those japanese footpads that supposedly draw the toxins out of your body through your feet and after i used them the pads were dark and black and smelled like BBQ sauce.
ps. after much online research these footpads are in fact...a HOAX
from what i am told, the powder in the patch which supposedly draws out the toxins reacts to sweat and heat and by putting the patch on the area of your foot can't breathe so it sweats and when the sweat touches the powder it turns brown and creates the illusion of toxins on the pad.
Jeez, guys, as a scientologist, the only way to remove toxins is to take a lot of B vitamins, sit in a sauna, remove engrams from your mind, ignore galactic overlord Xenu's desire to make you forever unhappy, give all your money to the church, and do whatever Tom Cruise says.
The amount of time between eating an pooping normally speaks to a build up of impurities, slowing down your digestive processes, causing you to absorb an increased amount of whatever you just ate. Likewise, "toxins" can build up in your digestive tract this way. Similarly, toxins that reach the blood stream can make their way to your somatic cells and just accumulate there. Somethings in your body act the same way mercury does. Mercury is processed poorly and builds in your brain, eventually causing HEAVY METAL sickness. Toxins can act in a similar way. Different medical traditions have different ways of removing these toxins, none of which have been verified by laboratory research.
