Is there any poison to cure snake bite?

No, there is no such poison that can cure a snake bite. Snake venom is a complex mixture of proteins, enzymes, and other toxic substances that can cause a variety of symptoms, including pain, swelling, tissue damage, and even death. While there are antivenoms that can be used to treat snake bites, these are not poisons themselves, but rather antibodies that can help to neutralize the effects of snake venom.
