Ever tried the foot patch for detox? It seems to be quite popular lately and many versions of foot patches are sold in the market.. I too tried it.. and didn't find anything different from it.. but the patch sure turns into dark brown as expected, and the smell, goshhh.. busukkk.. Question is.. does this really work? Or just another marketing con like the foor detox where you put your foot in the water and stuff some time ago? Any ideas?
