Dr. Brown suggested the standard treatment of the day - substantial bleeding. He needs all of his strength and further bleeding will diminish it. The two older doctors overruled him and Washington, though having no medical training, concurred with them. The flow became very slow and thick as Doctor Brown took a full quart of Washington's blood. Calomel and tartar were also administered to the former general.
Calomel is a strong laxative while tartar is an emetic which causes vomiting.
Washington became weaker and weaker, giving instructions about his will. The two senior doctors thought the idea was too daring and, instead applied blistering agents to his legs and feet. Washington's breathing finally eased somewhat later in the afternoon when his breathing rate diminished. The first U.S. president died soon thereafter. It was December 14, 1799.
