People who practice urine therapy use their own urine to treat various medical conditions and other concerns, according to MedicineNet. Although there is no scientific basis for urine therapy, some people drink urine, massage urine into their skin, irrigate their sinuses with urine or otherwise apply urine to their body. Modern urine therapy practitioners believe that their urine could treat cancer, AIDS and other conditions, reports TIME.
Urine therapy proponents believe that the tumor antigens contained in urine can stimulate the immune system to create antibodies to fight cancer, explains MedicineNet. However, there is no proof that regular exposure to urine could treat cancer. Also, the amount of tumor antigens contained in urine is very small when compared to the amount of tumor antigens contained in the blood.
A few athletes use urine therapy to treat blisters or toughen the skin on their hands, states The Guardian. Other athletes drink their urine as a way to regain the vitamins they lost during urination.
Urine therapy, also called urotherapy or urinotherapy, is unlikely to be harmful and has ties to certain cultural traditions, notes MedicineNet. Historically, people used urine therapy because they believed it could whiten teeth, prevent infections and protect the skin. Some folk remedies, such as the remedy for jellyfish stings, also call for urine. However, there is no evidence these remedies work. In fact, applying urine to a jellyfish sting could cause further damage to the skin.
