There is a lot of discussion about Detox foot spas and whether they work. I purchased one of the cheaper ones in November and have used it on myself and my clients. They are quite amazing to watch and I regularly get clients coming in pairs so they can see each others foot spa as its happening. It has created much interest around our island.
The footspa works on principles of electrochemistry. The array is like a small element that is immersed in the water and places negative charge on the hydrogen in the water molecules. Negative hydrogen is supposedly absorbed via osmosis into the body and acts as a free radical scavenger. Free radicals are damaging to our cells and body and can set up disease states in our bodies, so removing some of them would seem like a good idea.
The footspa is filled with water, with half teaspoon of salt. After 30 minutes, some peoples water looks like the picture above. This client has had the strongest colouring of the footspa water of all the people who have used it. Her first 3 foot spas also had a lot of cream coloured foam around the arrays (supposedly Lymphatic in origin). Most people also have distinctive black particles (suggested heavy metal elimination) and some people have had small cheesy looking chunks (excesses of yeast).
The people who had a treatment remark that they felt more energised. Some felt pain around the teeth (amalgam fillings) or could feel stimulation around the lymph nodes in the groin, armpits and face/neck. It's all interesting and I think we'll find out much more about this relatively new treatment in the future.
