I saw a commercial for this product a while ago and found some information on
this
website.
It's supposed to remove toxins in your body by drawing them out through your feet. What the heck!?

Why are the patches worn on the feet?
The foot pads are worn on the feet for a couple of reasons - the feet are considered in Oriental medicine to be "the second heart" - that is, they
help pump return circulation of blood and lymph back up into the torso. With most of our time sedentary these days, this natural pumping action is
inhibited and circulation tends to bog down around the feet, ankles and lower legs.

What is actually coming out into the used foot detox patches?
This will vary from person to person, but lab analysis of used foot detox patches show a larger variety of chemicals coming out into the patches.
Testing shows traces of heavy metals, petrochemicals, synthetic chemicals, pesticides, herbicides and much more.
Wierd stuff. Has anyone ever tried this? Do you think anything like this could actually work?
