Nitric oxide cream on the site of a snake bite can slow the spread of venom in the victim's blood supply. Dirk van Helden from Newcastle University, Callaghan, Australia, tried the cream on mice injected with snake venom. Bites penetrate tissue rather than blood vessels, so the lymphatic system is the main route for toxins entering the blood. The cream affects the lymphatic system by slowing pumping. Extra time can allow victims to seek help.
