The powerful venom of the saw-scaled viper Echis carinatus contains both anticoagulants and coagulants finds a study published in the launch edition of BioMed Central's open access journal Journal of Venomous Animals and Toxins including Tropical Diseases. These may be a source of potent drugs to treat human disease. This snake is responsible for most human bites and its venom causes coagulopathy which results in symptoms of blood clotting, hemorrhage and stroke.
