As we all know, the body is composed of cells, human disease can eventually be attributed to cell damage, human aging is also due to cell aging or necrosis caused. The main culprit in causing cell disease aging is excess oxygen free radicals. The main effect of oxygen is antioxidant, hydrogen atoms combined with reactive oxygen species reduced to water excreted.
