Our nature is a big cabinet of medicine. So many hidden treasures are there, only needed to find out. Almost half of the medicine has been emerged from flora or fauna, surrounding us. That is an indication that there are many more yet to be discovered. For example, the bite of King Cobra is sufficient to kill a human but the pain can be used as a relieving agent for pain during surgery and chronic pain. Cobra toxin is 20 to 200 times more potent analgesic than morphine.
