Scientists have discovered that acupuncture prevents toxins from damaging the lungs. In an incredible investigation, microphotographs reveal that bilateral electroacupuncture at acupoints ST36 and BL13 successfully protect the lungs from endotoxic shock when exposed to injurious toxic exposure. Immunofluorescence analysis reveals an important secret power of electroacupuncture; it stimulates an increase of Nrf2 nucleoproteins that are responsible for increased expression of protective antioxidant enzymes.
