Blood is undeniably linked to life and has often been described as the river of life for several good reasons. It transports life-preserving oxygen from the lungs to body tissue, and then picks up carbon dioxide from body tissue and brings it back to the lungs. It also delivers nutrients from the food we eat to our cells, cruising through the liver first where the nutrients are detoxified. Blood significantly benefits from periodic cleansing, and a few key supplements are highly beneficial for accomplishing the process.
