  • Draculin is an anticoagulant found in the saliva of vampire bats. It inhibits coagulation factors IX (IXa) and X (Xa), thus keeping the blood of the bitten victim from clotting while the bat is drinking. It is twenty times stronger than any other known anticoagulant and is prescribed for heart attack and stroke patients.
