Contrary to popular belief, urine is actually a by-product of blood filtration and not waste filtration. Medically, it is referred to as plasma ultrafiltrate. It is a purified derivative of the blood itself, made by the kidneys whose principal function is regulation of all the elements and their concentrations in the blood. Nutrient-filled blood passes through the liver where toxins are removed to be excreted as solid waste. Eventually, this purified blood undergoes a more extensive filtering process in the kidneys, where excess components not usable at that time by the body are collected in the form of the sterile, watery solution that is urine.
Far from being harmful, urine contains known healing agents. Clinical studies have proven that the thousands of critical body chemicals and nutrients that end up in urine reflect the individual bodys functions. When re-utilized, these chemicals and nutrients act as natural vaccines, antibacterial, antiviral and anticarcinogenic agents as well as hormone balancers and allergy relievers." [show less]
