Drinking Cranberry As a Complementary Health Approach

Cranberries, the fruits of a native plant of North America, are widely used in food and herbal products. They are most popular as a remedy for urinary tract infections or for dental plaque prevention. Below are information by the National Center for Complementary and Alternative Medicine (NCCAM) on cranberries.

What Science Says

-There is some evidence that cranberry can help to prevent urinary tract infections; however, the evidence is not definitive, and more research is needed. Cranberry has not been shown to be effective as a treatment for an existing urinary tract infection.

-Research shows that components found in cranberry may prevent bacteria, such as E. coli, from clinging to the cells along the walls of the urinary tract and causing infection. There is also preliminary evidence that cranberry may reduce the ability of H. pylori bacteria to live in the stomach and cause ulcers.

-Findings from a few laboratory studies suggest that cranberry may have antioxidant properties and may also be able to reduce dental plaque (a cause of gum disease).

-NCCAM is funding studies of cranberry, primarily to better understand its effects on urinary tract infection. The Office of Dietary Supplements and other National Institutes of Health (NIH) agencies are also supporting cranberry research; for example, the National Institute on Aging is funding a laboratory study of potential anti-aging effects.

Side Effects and Cautions

- Drinking cranberry juice products appears to be safe, although excessive amounts could cause gastrointestinal upset or diarrhea.

- People who think they have a urinary tract infection should see a health care provider for proper diagnosis and treatment. Cranberry products should not be used to treat infection.

-There are some indications that cranberry should be used cautiously by people who take blood-thinning drugs (such as warfarin), medications that affect the liver, or aspirin.

-Tell all your health care providers about any complementary health practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
