In the present article, we reviewed plants and phytochemical compounds demonstrating beneficial effects in pancreatic cancer to find new sources of pharmaceutical agents. For this purpose, Scopus, PubMed, Web of Science, and Google scholar were searched for plants or herbal components with beneficial effects in the treatment of pancreatic cancer. Data were collected up to January 2013. The search terms were “plant,” “herb,” “herbal therapy,” or “phytotherapy” and “pancreatic cancer” or “pancreas.” All of the human in vivo and in vitro studies were included. According to studies, among diverse plants and phytochemicals, 12 compounds including apigenin, genistein, quercetin, resveratrol, epigallocatechin gallate, benzyl isothiocyanate, sulforaphane, curcumin, thymoquinone, dihydroartemisinin, cucurbitacin B, and perillyl alcohol have beneficial action against pancreatic cancer cells through 4 or more mechanisms. Applying their plausible synergistic effects can be an imperative approach for finding new efficient pharmacological agents in the treatment of pancreatic cancer.
