Cleansing Detox Foot Patches with Ginger & Salt . The primary effect of the Kinoki Detox Foot Pads is detoxification. The patches will absorb your toxins after using for whole night. You can see that from the changing of the color after using it. The more dirty you see the foot pad, the more toxins it has absorbed. After consistently using for a period, they will become cleaner each morning. That means most of the toxins in your body have been released already. Apart from your feet, you can also apply these detox foot pads onto other part of your body, including back, knees, elbows etc.
