Cranberry Juice & Urinary Tract Infections: What the Science Says

Studies on everything from cavity prevention to heart disease are measuring the health benefits of cranberries. While many people believe cranberry juice to be a cure for urinary infections, thus far there is no substantial proof that it is effective in the treatment of this condition.

Identification

• Tart and sharp, cranberries are the red fruits of a perennial shrub of the Vaccinium family.

History

• Cranberries are one of the few fruits indigenous to North America. They are typically harvested in the fall.

Uses

• Uses for the berries include juice and fresh as well as dried fruit. Native Americans also used cranberries as a source of red dye for their cloth.

Benefits

• According to studies conducted by the National Institute of Health, there is no conclusive evidence that cranberry juice aids in the treatment of a urinary tract infection. Some studies do suggest it can be helpful as a preventative measure and to promote urinary tract health, though it is unclear what dosage is most effective.

Warning

• Urinary tract infections can lead to conditions that are more serious. It is always wise to consult your physician before beginning any treatments.
