Urinating on wheat for pregnancy test .Using wheat to define whether a woman was pregnant is one of the oldest known tests. It dates from 1350 BC and consisted of urinating on the wheat and barley seeds: if they sprouted it meant that she was pregnant. To define the sex of the baby, the test depended on the seed that would germinate. If the wheat did, it was a girl and for barley, a child. A test conducted in 1963 showed that this method had an efficacy of 70% when it came to determining pregnancy.

Urine was used by Romans to wash clothes and making leather. In the laundries or fullonicas of the Roman Empire collected urine and left it to rest until it decomposed.The stored urea eventually becomes ammonia.And that ammonia was one of the detergents with which the clothes of the nobility were washed.

The Roman philosopher and writer Seneca tells that after soaking the white wool robes, the workers or fullons jumped or danced on them, and used fullonica chalk ( fuller’s earth), urine and sulfur, to eliminate the fat and enhance the colors. (Epistulae 15.4)Then they were rinsed again to remove the smell of fragrant detergents.

Among them were also those who worked with leather.Urine was the perfect substance to soften and tan animal skins, because the high pH of ammonia decomposes the organic material.Soaking the skin of animals in the urine also facilitated the removal of hair and pieces of flesh from the skin.

The Romans taxed urine .Fullonicas were turning into such a good business that, when Vespasiano came to power the urinae vectigal was invented , a tax that had to be paid by those who wanted to use the urine that was collected in the Cloaca Maxima in Rome. Source

Historical uses of urine

The most widespread use of urine is that of a diagnostic method of our physical and mental health. In the Middle Ages, the patient’s urine test was the most reliable way to determine a disease.

Without equivocation, it can be said that for thousands of years the yellow liquid has been present, in a useful way, in the customs and traditions of dissimilar cultures.

In the 1st century BC, the poet from Verona (in present-day Italy ) Catullus , tells in one of his poems that urine was used to brighten teeth, while in the ancient city of Pompeii and Rome , that of the population It was collected in special jars distributed along the street.

And is that fermented produces ammonia, which, although unpleasant for smell, was used as toothpaste and stain remover in the laundries of the time. This liquid was also used for the tanning of skins in the textile industry, perhaps because of some of the enzymes it has.

History also refers to the use of urine in China : there it was even used for cosmetic purposes; Highness Lady Yang, of the Tang dynasty 618-907 , sprayed her body with children’s urine to preserve, according to Eastern tradition, her youth and beauty.

In Spain, urine was also used for this purpose. A jug of this fluid was added to the bath water, a custom that was exported to the Americas and some texts from the early nineteenth century mention that in Florida and California was frequent for bathing.

During the Middle Ages and the beginning of the Modern Age urinalysis was the diagnostic method most used by doctors. It is narrated in the bibliography of the time that the physicians poured the patient’s urine into a special glass and holding it between their fingers stretched the container upwards to inspect its contents against the light.

The sample was also smelled and if necessary it was tested with the tip of the tongue, in case its taste was sweet the patient suffered from diabetes.

In addition to the state of health, the examination of the yellow liquid informed on the psyche; this is how it is read in books of the Renaissance : if the urine is white and thick, its wearer is phlegmatic, cold and solitary, while the reddish and watery one corresponds to passionate, dry and angry people.

Popular medicine has mistakenly resorted to this fluid as a remedy against the most diverse ailments. So it is referred to in the sixteenth century , that to stop nosebleeds it was recommended to rub the nose with urine, preferably as an ass, and also to fight fever by drinking a glass of this liquid for three days.

Even in recent literature, referring to natural medicine, it is spoken, as if we were still living in the Middle Ages, of its use as an elixir proper to good health. But its therapeutic benefits are not proven and are condemned by specialists. For nephrologists and urologists , urine is nothing more than a liquid made up of water, urea and a residual mixture of minerals, salts, hormones and enzymes.

What does the color of urine tell us?

The color , transparency , smell or amount of foamin the urine tells us many things, for example, about our state of hydration. But you can also alert us about some diseases, not only urinary:

urine color

  • Light yellow urine: the typical yellow color is normal, and is due to the presence of urobilin mixed with water. If we drink more, the urine is lighter, and if we drink less, the urobilin is more concentrated and darker. If the urine is very clear but we have not drunk much, it could indicate diabetes.
  • Orange urine: may simply be due to carrot or beet consumption. But it can also indicate a liver problem. If you have not consumed those foods, you should go to your doctor.
  • Greenish blue urine: asparagus intake or greenish blue dyes in food. Some bacteria that cause urine infections can also give this color.
  • Brown urine: beans, beans or beans can produce that color, and also some medications.Intense dehydration, or some liver problems can also cause this color.
  • Pink or reddish urine: it can be produced by blueberries and other red foods. Also for intense physical exercise. But without these triggers it is usually the presence of blood in the urine, which can be due to an infection, a kidney stone or more dangerous causes such as bladder or urinary tract tumors. If the urine is red it is always recommended to consult a urologist as soon as possible.
  • Urine with a strong smell: asparagus or coffee can produce it. Also urine infections.
  • Cloudy urine: it may be due to urinary tract stones, but most often it is accompanied by a strong smell and the urge to urinate many times.This occurs in urine infections.
  • Foamy urine: it is due to the presence of protein in the urine. Proteinuria should always be studied, because if it is not due to an excess of protein in the diet, it can translate a kidney problem.

The general recommendation is that any alteration in the color of the urine or its characteristics wait 24 hours to see if it is corrected. But if it persists, or is accompanied by other symptoms such as pain or fever, or it is red urine, consult your doctor soon!

Interesting facts about urine and our body

After the production of urine by the kidneys, it goes through the ureters to the urinary bladder where it is stored and then expelled to the outside of the body through the urethra , by urination.

An adult urinates about eight times a day, devoting about two minutes in total to this task. Urologists estimate in a general way that humanity generates more or less 60 million liters of this fluid every day.

A normal urine drainage should take about seven seconds. Also varies from person to person. But if you pee very briefly, around two seconds, even though you felt very necessary, it could be a sign that you have some infection, says urology professor Benjamin Brucker at NYU Langone Medical Center.

Urine consists of 95 percent water.Only three percent are urea and other ingredients are chloride, sodium potassium and creatine, as well as other even smaller ingredients.

The bladder of an average person can store 300 to 500 ml of urine. Interestingly, unlike what you might have heard,  height is not related to the capacity of each person’s bladder . In general, the average volume of a bladder is quite similar among adults.

Composition of urine

Urine is an organic fluid secreted by the kidneys by filtration of blood. It contains more than 3,000 chemical compounds  :

  • It contains mainly water (95%), urea (2%) resulting from the breakdown of the body’s proteins and creatinine (0.1%, product of the breakdown of muscle creatine).
  • It also contains mineral salts: magnesium, calcium, potassium (0.6%), sodium (0.1%), chlorine (0.6%), sulphates, phosphates and carbonates.
  • It also contains amino acids, enzymes, certain vitamins, uric acid (resulting from the degradation of DNA among others), allantoin, DHEA (hormone produced by the adrenal glands, known for its anti-aging effects), urobilin (yellow pigment giving color to the urine) or small proteins.
  • Also present are the degradation products of the assimilated drug treatments.

The most important organ of the urinary system are the kidneys , bean-shaped structures that are located under the ribs in the middle of the back. Its function is to eliminate the urea from the blood and channel the urine to the bladder.

The composition is relatively stable from one day to the next. It allows the elimination of the waste of the cellular metabolism and the maintenance of the constants of the organism

Normal urine does not contain bacteria. It does not contain glucose or large proteins. It may contain some white blood cells and red blood cells.

How much urine can the bladder store?

The bladder can store almost half a liter of urine for 2 to 5 hours without causing discomfort to the person. At the exit of the bladder there are muscles called sphincters that close tightly to avoid any spontaneous leakage.
