The principle is that the foot patch is attached to the sole of the foot, the drug is absorbed through the skin under the action of the transporter, and harmful substances are eliminated through the skin with blood circulation; Harmful free radicals in the body will also combine with ions in the foot patch and be eliminated in the form of diffusion.

Traditional Chinese medicine believes that exogenous diseases are wind, cold, summer, dampness and fire dryness, which are similar to immune antigens and act on meridians, causing disharmony between qi and blood, reaching the five internal organs and causing qi disorder. As a result, some waste toxins similar to cell and tissue metabolism have been produced, which have been scientifically proved to be carcinogens. The clinical understanding of traditional Chinese medicine is that there are many cold pathogens in the north, which often invade the meridians of lower limbs, resulting in blood stasis. It is also the deficiency of qi and blood in western medicine. Cold pathogen can also go straight into the middle energizer and invade spleen yang, resulting in obstruction of the third energizer and accumulation of sundries. Protein, who is also a western doctor, absorbed too much fat in the small intestine. Probiotics can affect chorionic cells. The hot and humid weather in the south, mixed with wind and heat, often leads to inflammation of liver fire, which will disturb the heart fire and trap the triple energizer.
