title: Theoretical foundation of the medieval preparations of urinary derivatives.
abstract: It has been recently brought to light that the Chinese, as early as 1025 A.D., had already devised a preparation which would extract hormones from urine. This paper attempts to trace the development of Chinese medical thought, from 25 A.D., which had led to such a sophisticated preparation.
