Carrageenin is not an antithrombin. It inhibits fibrin aggregation or polymerisation. The inactivation of thrombin by antithrombin and of blood thromboplastin by anti blood thromboplastin is neither accelerated nor retarded. In the presence of Carrageenin the clotting times of tests in which the fibrinpolymerisation phase is involved are lengthened; this simulates a decrease in clotting factors. In vivo Carrageenin, despite its coagulation-inhibitory properties, is not able to reverse the consumption reaction which it has initiated.
