Plant Physiology Mimics Animal Physiology
As they are eaten by insects, chemical reactions almost identical to the neurohormonal reactions that regulate pain and injury repair in animals surge through plants. When leaves get nibbled, they release a hormone resembling the endorphins made by animals after injury. So similar are these chemical responses to injury that a sprinkling of aspirin or ibuprofen on plant tissue will squelch the reaction, as it does in people.
