Cranberry
Does cranberry work?
Evidence suggests thatcranberryjuice or extract can help prevent UTIs from recurring during the following 12 months, but this effect is small.Cranberrycannot treat active UTIs. However, evidence has been somewhat inconsistent. Natural unprocessedcranberryjuice contains anthocyanidins, which preventEscherichia coli(the bacteria that usually cause urinary tract infections) from attaching to the urinary tract wall. There is no evidence thatcranberryis effective for reducing fever or treating certain cancers.
