Combing with the personal information water (I-water), natural cellular defense （NCD）, and AgariGold, the kidney detoxification is a non-invasive kidney cleansing method without any side effect. Regardless of age, one can do it at home. The I-water delivers NCD to kidneys, and the NCD will attach the toxic and metallic residues attached on the walls of the tubules in the kidneys. Since the I-water carries the personal information through magnetism, the I-water can attract the residual toxins and remove it from the body through the urine. AgariGold contains nutrients that are beneficial to the recovery of the kidneys. Therefore, after kidney detoxification, AgariGold can rapidly help recovery of the kidney tubules damaged biochemically by the toxins, metals, and medications.
