It is known as an Ionic Foot bath; a foot bath to facilitate the process of detoxification of the body by way of the feet. While many are skeptical of the whole process, others do claim that it helps detoxify the body.
Toxic build up of heavy metals in the body which can lead to aches and pains, tiredness, and lowered immunity, are sought to be removed by the Ionic Foot bath.
Sessions can be conducted in spas and salons or you can buy an ionic foot bath for your home use as available on Amazon.
The process basically involves submerging the feet in salt water and initiating an electric current – now this may sound positively dangerous so if you do decide to engage in this you should be fully appraised of how to work the device.
There is supposed to be a release of toxic substances into the water which discolors it – many people dismiss this as quackery whereas other claims to see and even smell the release of heavy metals into the water and say that the process causes the diminishing of all kinds of chronic aches and pains.
It is also claimed that there is no need of any particular device; you can get good results just by soaking your feet in salt water each night.
