Since two of these four humors were thought to be bile, our predecessors apparently attached much importance to this natural body product. These early commentators certainly were correct in this belief. However, it has required the more modern methods of science to give us a fairly clear concept of bile.
There are many gaps in our knowledge, but the combined work of physiologists, pharmacologists and chemists during the past several years has served to clarify our understanding of the physiology of bile and the use of bile in therapy.
