Urea - Long

[Guest guest]

Hi Ann,

Confusing diazolidinyl urea and imidazolidinyl urea, two urea compounds

used as preservatives in many

commerical products with simple urea is a big mistake, *huge*.

I have gathered some information that may help clear up the confusion

and prevent the spreading of further misinformation.

Urea is an extremely beneficial compound and one to be highly valued in

its natural form. I have to

step in here and defend what is an essentially free and life saving

substance that we all have with us

all the time. I would simply hate for anyone to be misled into thinking

that urea is a bad thing! LOL

Urea helps with the reabsorption of water and ions, to conserve these

components and prevent them from

being excreted in the urine by the kidneys when the body needs them. It

does *not* remove toxins in the kidney.

And it does not absorb toxins, but it is an excellent humectant, that is

it holds water so makes an excellent

moisturizer for skin. It is an ancient beauty secret in the form of

urine and which also functions as an exfoliator.

Historically urea, as a component of urine, was used for its many

beneficial properties in healing

wounds. It has a 5,000 year history and is one of the most ancient

substances collected and used by man for many purposes including as a

cleaning agent for laundry, the ammonia that develops from old urine

within ten minutes of

being exposed to air is an excellent degreaser. Urine when it exits the

body is a sterile substance and contains a

wide range of beneficial compounds which is the basis for its

therapeutic use in Amaroli or the ancient practice

of auto-urine therapy.

http://groups.yahoo.com/group/Urine_Therapy is a list of over 1500

practitioners. Check out the links and files section for some great free

information on this free life saving therapy. If you are ever trapped by

a natural disaster,

stung by a sea urchin, or without clean water you will be very glad you

know about the value of Amaroli.

Urea can be synthetically produced and is used in many ways including in

animal feed, fertilizer and to produce many chemicals and

pharmaceuticals. Urea is a very simple molecule, consisting of two atoms

of nitrogen and four atoms of hydrogen.

What is found in some commercial toothpastes, shampoos and cosmetics are

the *compounds* olidinyl urea and its close cousin, Imidazolidinyl

urea. Which are *not* and should not be confused with simple urea. These

are more complex compounds that have as a component, a molecule of urea,

but they are not simple urea and should not be confused with simple

urea. Both of these are more about the formaldehyde that is released

than the urea moiety of the molecule. The purpose of these compounds are

to release formaldehyde as a preservative, also known as formalin and

commonly used to preserve tissue and whole animal specimens in laboratories.

" The handling of urea by the kidneys is a vital part of human

metabolism. Besides its role as carrier of waste nitrogen, urea also

plays a role in the countercurrent exchange system of the nephrons, that

allows for reabsorption of water and critical ions from the excreted

urine. Urea is reabsorbed in the inner medullary collecting ducts of the

nephrons,[4] thus raising the osmolarity in the medullary interstitium

surrounding the thin ascending limb of the loop of Henle, which in turn

causes water to be reabsorbed. By action of the urea transporter 2, some

of this reabsorbed urea will eventually flow back into the thin

ascending limb of the tubule, through the collecting ducts, and into the

excreted urine.

This mechanism, which is controlled by the antidiuretic hormone, allows

the body to create hyperosmotic urine, that has a higher concentration

of dissolved substances than the blood plasma. This mechanism is

important to prevent the loss of water, to maintain blood pressure, and

to maintain a suitable concentration of sodium ions in the blood plasma. "
