The foot pads contain natural ingredients which stimulate these acupuncture points through the combined action of wood/bamboo vinegar, far-infrared energy and negative ion emissions. This stimulation results in the breakdown of water and waste molecules that free blockages in the circulatory and lymphatic systems. Cleansing naturally begins in the soles of our feet. The primary effect of the 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.Ingredients: bamboo vinegar, chitosan, dextrin, dokudami, loquat leaf, tourmaline, vegetable fiber, Vitamin C and wood vinegar.
