hi ive been using detox foot pads for the last 3 months, and ive founf them very usefull, i find i sleep much better, and have noticed an improvement in my energy levels. The actual discoloration of the detox foot pads is only the natural ingriedients reacting with fluid (sweat exspelled from your body) the brown stickyness is not what is being removed. What is happening is that toxins are being exscreted in the sweat and absorbed in to the patches
The ones i purchased are called nova detox foot pads, from
http://www.novadetox.co.uk I shopped around and found these to be the best price with free UK delivery, this was a bonus,
