I've not had it done, but I've heard that you feel 'awake' and more lively after having it done.

Am sure I've seen some other treatment that works through electrolisis, you put your feet in a bucket of water and a small current is directed into the water ... then into your body. It causes the body to release the toxins in the skin, and eventually the water turns black (but I think the colour differs depending on what toxins you have)
