ionic foot baths aren't so much about what comes out in the water. i've found the real effect comes from the negative ions that are created to help restore and rebalance the body. i get some serious healing crisis from detox foot baths. about 1 more after a treatment i feel slightly nauseous and get a little bit of a racing heart. these are symptoms of the detoxification process....at least in my case. after that passes i sometimes feel remarkable. this is a powerful healing tool and definitely not a day at the spa for me.
