Cranberry
Overview
Cranberry (Vaccinium macrocarpon) is an evergreen shrub that grows in bogs in North America. It produces dark red fruits that contain salicylic acid.
Chemicals in cranberries keep bacteria from sticking to the cells in the urinary tract. But they don't seem to be able to remove bacteria that are already stuck to these cells. This might explain why cranberry helps prevent urinary tract infections (UTIs), but doesn't help treat them.
People commonly use cranberry to prevent UTIs. Cranberry is also used for kidney stones, enlarged prostate, the common cold, and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse cranberry with cramp bark, lingonberry, or uva ursi. These are sometimes also called cranberry but they are not the same.
