First, urine can extract useful urinary proteases, such as urokinase for male thrombotic diseases and ulinastatin for pancreatitis, gonadotropin for infertility in the urine of elderly women, chorionic gonadotropin for pregnancy test stick in the urine of pregnant women, and urinary peptide for cancer.
Second: urine can be used as fertilizer. Urine contains inorganic salts such as nitrogen, phosphorus and potassium. Phosphorus: promoting the flowering and fruiting of plants; Potassium: make the plant stem strong), which is very helpful to plant growth, commonly known as "farm manure"
Third: if you are scratched in the wild, there will be many germs in the wound. If there is no disinfectant, you can use the middle urine to clean the wound and go to the hospital in time, but be careful not to use the urine just discharged to clean the wound or store the urine for later use. (In general, middle urine can basically be considered sterile. When there is no detergent in an emergency, you can use urine to wash the wound for cleaning. But be sure to go to the hospital in time)
Combining the above three uses, it shows that our urine still has many uses, and I hope it will be useful to you.
