In the event of a snakebite, it is best to immediately tie a knot above the location of the bite with a piece of string, or even higher in the wrist area if the bite hits the hand. Use a knife to cut open the wound to help the venom drain out.

Must be sent to the doctor in time, there is no serum if you can find the local there is no snake catcher they have a kind of snake medicine called even if the cobra bite as long as you eat this will be fine!
