Scientists have made great progress in finding within this new-found knowledge of venom any benefits for humans. The biggest role of the snake venom is used to produce “antivenom” now. Besides the obvious benefits to produce antivenom, there are many exciting discoveries in various studies that gives promise on many medical fronts. In Israel, A company is using snake venom to make a potent analgesic against chronic pain such as arthritis, and secondary pain caused by other diseases such as cancer.
