Cranberries! - A Healthy Superfruit
(Vaccinium oxycoccos)
Cranberries have long been valued for their ability to help prevent urinary tract infections by preventing E. coli from adhering to the cells that line the urinary tract1,2. This same effect may help prevent other types of infections involving host-tissue bacteria such as H. pylori, a major cause of gastric ulcers3.
Cranberries are a potent source of antioxidants, specifically from a subclass of flavonoids called proanthocyanidins (PACs), which are unique and abundant in cranberries. The antioxidant properties of PACs may have a range of other health benefits, including supporting cardiovascular health. However, there has been some discussion concerning cranberry-warfarin interation6. If you are on blood thinning drugs, please consult your doctor with regard to possible herb-drug interactions.
