Провели опыт над крысами, пришли к заключению, что урина действительно заживляет раны, и при наружном, и при внутреннем потреблении (10 мл/кг). Причем, использовалась человеческая урина.

Urine is used traditionally in India for the treatment of burns and wounds. It is believed that applying urine over the wound increases healing. The present study was carried out to evaluate the effect of human urine, urea (2.5%), and urea (5%) on experimentally induced wounds in rats and compare the effects observed with an antiseptic agent, povidine iodine solution. The models selected were excision wound, incision wound, burn wound and dead space wound. In the excision wound and burn wound models, a significant decrease in period of epithelization and wound contraction-50% was observed in all the treatment groups when compared to control except low dose of urea (2.5%), which showed reduction in only period of epithelization. In the incision wound model, a significant increase in the breaking strength was observed. Human urine treatment orally produced a significant increase in the breaking strength, dry tissue weight and hydroxyproline content in dead space wound model. It was concluded that human urine applied topically or administered orally (10 ml/kg, p.o) possesses wound healing activity.
