It's very bad to interfere at the site of the bite. You shouldn't make incisions, cut marks with a dirty penknife or anything else. You shouldn't suck out the venom, you shouldn't apply a tight band or tourniquet to obstruct the blood flow, you should not apply an electric shock which has been quite popular and fashionable recently, in recent years. All these very popular remedies for snakebite are far more harmful than they are beneficial. The key thing to do is to try to immobilise the bitten limb because the more you contract your muscles in the arm or leg that's been bitten, the more likely you are to pump venom into the system. So try to immobilise the limb, with a sling in the case of the arm or a splint in the case of the leg, and if you have such a thing, a very good way of keeping the limb still is to bind it up with a long, stretchy bandage, a crepe bandage.
