Well, well. I have heard enough about those pads and decided to make a little experiment.

I love experiments you know and posted quite some concerning gall stones in Liver Flush Forum s.

I used the ones called K.......ra.
I put one pad on a foot of my husband, according to the instruction provided. It turned brown and sticky in about half a hour. My husband is a very healthy person. I suspect it is all about sweat.

I sacrificed another pad and cut it in two pieces. Inside was some light greenish powder that made me sneeze. I spited on one half with some powder still inside and pressed it slightly to sort of imitate conditions it would be exposed to on my foot. It turned green brownish and sticky.

I put the powder from another half of pad on a paper in three different little piles. One pile was mixed with my saliva, another one with urine, tird one with pure water.

First two turned brownish. All of them got sticky. On the first two there were also some strange micro dots of something that became visible and brownish after they came in contact with the liquids. I moved it a little with a tooth pick and it moved leaving a brown trace. Manganese crystals behave the same with water. But this time it was really someting micro and that was coloring the pads brown.

I left it all, including the pad from my huspands foot, to stay in a open air for a couple of days. They all remained sticky, no drying process, due some chemical components I guess.

Quite suspicious product I must say.
Anyone can try the experiments themselves.

Conclusion:

1. Pads get brownish and sticky whenever they get in touch with enough sweat or other body liquids.

2. Colour of the pads does not in any way indicate presence of toxines.

Advise:

Test ingredients of the pads in laboratory BEFORE and after applying them on your foot, before making any decisions on using them constantly.
