Various adhesive pads and patches are claimed to detoxify the body when applied to the feet. The best known is the Kinoki Detox Foot Pad, which is claimed to remove toxins, restore "balance" within the body, and boost energy. Various other products are claimed to strengthen the immune system, reduce stress, improve circulation, improve sleep, enhance mental focus, relieve headaches and arthritis pain. The alleged explanation for their working include reflexology, unblocking of lymphatic passages, and negative ions that release far infrared rays. All such products should be regarded as fakes, and the proposed mechanisms should be regarded as nonsensical.
