Warfarin
The discovery of warfarin, a powerful anticoagulant, unfolded in the 1920s when farmers in the U.S. Midwest noticed an unexpected phenomenon among their cattle. Cows that consumed spoiled sweet clover hay were prone to uncontrolled bleeding, leading to fatal hemorrhages. Intrigued, scientists investigated the cause of this mysterious bleeding disorder and eventually isolated a compound responsible for the adverse effects. This compound, which was later named warfarin, exhibited potent anticoagulant properties. Through subsequent research and development, warfarin was refined and eventually found applications as a life-saving medication in the prevention and treatment of blood clots.
