Warfarin (sometimes sold as Coumadin) is a powerful water-soluble compound. It prevents blood from clotting. It does that by reducing the production of factors by the liver that promote clotting. It is called an "anticoagulant agent". It is a powerful rat poison. In concentrated form, it causes bleeding of internal organs which leads to death.[1]

It is also used, in very low doses, to prevent thrombosis in humans.[2] This is the local coagulation or clotting of the blood in the circulatory system. In such cases, it makes heart attacks, strokes, and pulmonary embolism less likely.[2] The degree of anticoagulation is monitored by blood tests.
