At an ionic foot bath session, users immerse their feet in a basin filled with salt water. Electrodes in the water add a small electric charge.

As this happens, the clear water in the bath starts to turn brown, black or even orange. Some companies claim that users experience reduced pain, higher energy levels and relief from allergies, insomnia and other conditions after a treatment. *results may vary"
