If it's what I'm thinking of, you put your feet in
ionic-charged water and it is supposed to draw
toxins out of your body and into the water. Supposedly
the water turns all kinds of nasty colors. I have
no personal experience with it.

However, I read a post somewhere where someone had spend
a long time doing ozone saunas, working through the rashes,
etc. Later, someone asked them if they wanted to try an ionic
cleanse and they agreed. The person who administered the
it was shocked that the water stayed clear. It was
the first time this had ever happened in their experience.

So, apparently ozone sauna will probably to the same thing.
That's just my conjecture, though.

I was watching a Christian health show on Daystar TV and they had some homeopathic experts as guests that filled a large bucket up with water and added Sea Salt ...They then turned on some type of ion or negative ion generating machine with some type of electrode in the water an ionized it with negative ions I think..

They then asked a volunteer from the audience to stick their feet in the water..After a period of 30 minutes or so (guestimation) the water turned dark brown with oil looking deposits and chunks of stuff started clumping together and floating on the top...Apparantly it's a very powerful way to cleanse.

After I saw that I really wanted to try it...I told my wife about it and she really wants to try it as well.

Is Ionized Water the same? Just about all I drink is Ionized Water . I've been drinking it for just about two years now. I love it & fell a lot better from it. I set it to 10.5 on the ph scale.
I'm pretty sure it makes the water neutral? It says, "during electrolysis attracts positive & negitive ions." You are supposed to keep it in a glass container as a result. All I know is it does a great job at making you feel healthier.

After having heard other people's astounding reports, I have had ionic foot bath treatments and am in the process of buying one myself. All I can say is that you have to try it to believe it.
How it works: The metal arrays in the foot bath water in conjunction with salt will create, depending on the polarity setting, negatively or positively charged ions. These machines are usually set to create mostly negative ions, with a short period of positive ions. It is believed that most toxins in the body have a positive charge, and that the negative ions in the water attract the positively charged toxins, through osmosis pull them out from the body. It is true that what you see in the water after a 30 minute session is partially the result of what is in the water and in the metal arrays. However this accounts only for some of the colour. the rest comes from the person's feet.Different people with their different problems will produce different coloured water! I have seen it. Further, I find that the foot bath make my feet tingle in a very pleasant way, is if they were coming alive, and this sensation lastes for hours after the treatment. My level of energy has improved, my sleep is healthier and I require less of it and wake up refreshed.
The principle of operation is similar to that of the foot patches. Over time I have tried several hundred of those, did not find the positive results I get with the ionic foot bath.
