The Spleen: A Vital Organ You Need to Understand Now

10. Ancient Medicine

In ancient Greece and throughout the medieval period, many physicians thought the spleen was an organ crucial to human life. They believed that the body required four humors kept in balance to stay healthy. One of these four humors was black bile, and physicians thought the spleen created it. If a person had too much of this bile, they would become depressed. However, because doctors believed the spleen could cleanse excess bile as well as create it, they viewed the spleen in a positive light.
