Traditionally, cranberries were used as a poultice to dress wounds, and to prevent or treat scurvy as they have a high content of vitamin C. More recently it has been recognised that cranberry juice has a beneficial effect on the urinary tract to reduce the incidence of urinary infections. Cranberries inhibit the adhesion of harmful micro-organisms to the cells of the bladder, creating a less hospitable breeding environment for E.coli and other disease causing bacteria. Cranberries also possess strong antioxidant properties and can help to deodourise urine.
Research has shown that drinking 300ml of Cranberry juice daily can almost halve the risk of developing cystitis. If a urinary tract infection is suspected medical advice should always be sought, especially during pregnancy
