The problem with the detox foot pads is they ask the body to cleanse without giving the toxins an exit. If you do just the foot pads without colonics or enemas or P&B shakes or detox baths, then the toxins just float around your system and make you feel terribly ill. They can't all exit from the feet! The feet are not a path of elimination, they are just a way to administer poultices.
Gotu Kola is an herb that helps to feed adrenals, but cleanse thoroughly first as it is an estrogenic and so can monkey up the hormones if the liver isn't clean.
