Some snake venoms are harmful because they contain enzymes that increase the rate of a reaction that destroys blood cells and tissue cells. The damage caused by such a snakebite could best be slowed down by applying ice to the bite area in order to decrease the temperature of the cells
inducing vomiting in order to remove all of the stomach contents
drinking large amounts of water in order to hydrate the cells
elevating the bite area in order to increase the number of blood cells present
