Clotting agents are substances that help the body stop bleeding by promoting the formation of blood clots. They work by enhancing the natural clotting process, which involves platelets and proteins in the blood. Common examples include fibrinogen, a protein that helps form a mesh that traps blood cells, and thrombin, an enzyme that converts fibrinogen into fibrin. These agents are often used in medical settings, such as during surgeries or in emergency care, to control excessive bleeding. They can be found in various forms, including powders, gels, and dressings, and are essential for effective wound management and recovery.
