If you really were an herbalist - you would know what the makeup of urine is (urea).
In 1975, Dr. A.H. Free, published his book Urinalysis in Clinical Laboratory Practice, in which he presents a few critical nutrients found in urine:
Urine is a by-product of Blood filtration, not Waste filtration.
Urine is NOT a toxic waste product and this has been scientifically proven. 95% of urine is water, 2.5% consists of urea and the remaining 2.5% is a mixture of minerals, salt, hormones and enzymes.
Toxic substances - (waste products) are being removed from the body through the liver and intestines, through the skin and through breathing out.
You have confused the two. Urine is sterile - waste products are not.
