Tibetan medicine is virtually unknown outside Tibet and India and yet it is probably the most original and clinically oriented traditional system of medicine integrating the finest therapeutic techniques from the Indian and Chinese medical systems. One of the many unique aspects of Tibetan medicine is urinalysis used not only for its clinical value but also for prognosis. Urinalysis is based on clinical observation and theoretical knowledge. The purpose of this paper is to present a basic guideline of the 9 clinical characteristics of urine temperature and show how such variation in these characteristics has clinical significance. Major clinical features of urine associated with specific diseases like malignancy, asthma, osteoarthritis and cholelithiasis are discussed.
