Our detox 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 patches will absorb your toxin after using for whole night. You can see that the changing of the colour after using it. More dirty you see, more toxin it have absorb. After consistently using for a period, they willbecome less dirty. That means most of the toxin in you body have gone out already.
