Cranberry is an evergreen shrub; its berries are used in beverages, food, and dietary supplements. Whether cranberry helps to prevent urinary tract infections (UTIs), one of its most common uses, is unclear. It may benefit just certain groups, including women with recurrent UTIs. Large doses of cranberry may alter levels of warfarin, an anticoagulant (blood thinner). Anyone with symptoms of a UTI should see a health care provider for diagnosis and treatment.
