The concept of using magnets for healing dates back thousands of years to ancient Greece, Egypt, and China. Recent studies conducted at Baylor University have also supported the effectiveness of magnetic therapy. Besides containing iron, which is magnetically stimulated, human blood is composed of 90% water. During magnetic therapy, the hydrogen and oxygen molecules in the water, and the iron molecules, both become magnetically polarized and align with each other and other components in the blood stream. These charged and aligned molecules can then travel throughout the entire body more quickly and efficiently to provide the support for natural healing energy.  Note that magnet strength ("gauss") is measured by comparing the earth's natural magnetic field (0.5 gauss) to the bio-magnetic strength of the product.
