Yes, I have considered it. I probably wouldn't have tried them at all except for the testimonials I'd read by other people (on one of the footpad websites) of the pads relieving them from their coughs due to bronchitus. I don't see what is so different in their situation than from my own--both originated with an illness that was likely viral.
Not only that, but I've read in many places that most illnesses occur due to a build up of toxins in the body.
I'm definitely getting something out with these pads--it's just not helping the cough. Tonight, I'm trying the pad directly over my lungs instead of on my feet. Can't hurt to try it. *shrug*
