Hi there. I'm currently treating an upper respiratory disorder with fresh and sometimes old urine. I nebulise every morning and night; after 5 miserable years of health hell, nebulising urine has, in just a week, expelled green yellow thick sticky bloody mucus and I am now able to breathe easier and have more energy. Doctors have been baffled and unhelpful in my search for a cause, advising medication etc which I refused. Blessed am I to know the secret of my own medicine. I also drink fresh urine throughout the day and often fast on it until the family evening meal. I highly recommend urine for nebulising. Good luck and good health!!
