Urine is not, as many believe, the excess water from food and liquids that goes through the intestines and is ejected from the body as "waste". It is much different and much more. When you eat, the food you ingest is eventually broken down in the stomach and intestines into extremely small molecules. These molecules are absorbed into tiny tubules in the intestinal wall and then pass through these tubes into the blood stream.
The blood circulates throughout your body carrying these food molecules and other nutrients, along with critical immune defense and regulating elements such as red and white blood cells, antibodies, plasma, microscopic proteins, hormones, enzymes, etc., which are all manufactured at different locations in the body.
As the blood circulates, it passes through the liver where toxins are removed and later excreted from the body in the form of solid waste. Eventually, this now purified "cleaned" blood makes its way to the kidneys. When blood enters the kidneys it is filtered through an immensely complex and intricate system of minute tubules called nephron through which the blood is literally "squeezed" at high pressure. This filtering process removes excess amounts of water, salts and other elements in the blood that your body does not need at the time.
These excess elements are collected within the kidney in the form of a purified, sterile, watery solution called urine. Many of the constituents of this filtered watery solution, or urine, are then reabsorbed by the nephron and delivered back into the bloodstream. The remainder of the urine passes out of the kidneys into the bladder and is then excreted from the body.
The function of the kidneys is to keep the various elements in your blood balanced. When your body doesn't need something at a particular time, it is excreted - not because it is toxic or poisonous or bad for the body, but simply because the body does not need that particular element at the time.
Medical researchers have discovered that many of the elements of the blood that are found in urine have enormous medicinal value, and when reintroduced to the body, they boost the body's immune defenses and stimulate healing in a way that nothing else does.
A Nutrient Rich Powerhouse
In 1975, one of the founders of Miles Laboratories, Dr. A. H. Free, published his book Urinalysis in Clinical Laboratory Practice, in which he remarked that not only is urine a sterile body compound (purer than distilled water), but that it is now recognized that urine contains literally thousands of compounds. Among the urine constituents mentioned in Dr. Free's treatise is a list of nutrients that will knock your socks off. Here's just a few...
