All cucumbers belong to the botanical plant family called Curcubitaceae. This broad family of plants includes melons and squashes. The cucumbers we're most familiar with in the grocery store belong to the specific genus/species group, Cucumis sativus. As a member of the Cucurbitaceae family of plants, cucumbers are a rich source of triterpene phytonutrients called cucurbitacins. Cucurbitacins A, B, C, D and E are all contained in fresh cucumber. They have been the subject of active and ongoing research to determine the extent and nature of their anti-cancer properties. Scientists have already determined that several different signaling pathways (for example, the JAK-STAT and MAPK pathways) required for cancer cell development and survival can be blocked by activity of cucurbitacins. We expect to see human studies that confirm the anti-cancer benefits of cucumbers in the everyday diet.
