The only way to know for sure what is in your water after a detox session is to have a biofeedback scan to determine what toxins are in your body. There have been lab analysis experiments done where several hundred thousand dollars were spent with ever getting consistent results because current medical lab techniques can not tell what toxins are embedded in the bodies organs. What is left over in the water is just part of what happens in a detox session. The Bio Energy Field also helps energize and heal the body.
