On December 14th, 1799, former US President George Washington woke struggling for breath, his throat searing with pain.

00:18

He died later that day, from what’s suspected to have been a badly infected epiglottis, but not before he was prescribed an enema, steam therapy, and rigorous bloodletting.

00:32

During four bleeding sessions, Washington lost approximately two liters— roughly 40%— of his body’s blood supply.

00:42

And yet this wasn’t totally out of the ordinary for the time.

00:46

Bloodletting was a pervasive medical practice that dated at least as far back as ancient Greece.

00:54

Physicians like Hippocrates believed good health came from balance among what they called the body’s four humors: yellow bile, black bile, phlegm, and blood.

01:09

They attributed bad health to humoral imbalance, so treatments included purging, peeing, enemas, and bloodletting.
