Cranberry Effects in Urinary Tract Infections

Abstract

Cranberry is scientifically known as Vaccinium macrocarpon, belongs to the family of Ericaceae, and grows in humid environments, such as forests and swamps in North American countries. It is widely used by Native American peoples and by Europeans as a food and also in traditional medicine for health benefits such as cardioprotective and anticarcinogenic properties and prevention of stomach ulcers. Some studies have demonstrated the potential against bacteria that reach the urinary tract and cause infections. According to the research by Salo, the fruit is composed of 88% water, acid organic, fruits, vitamin C, flavonoids, catechins, and anthocyanidins. It can be found in the form of dried fruits, extracts, and juices, which usually contain only 10 to 25% cranberry concentrate. In addition, it was revealed that anthocyanidins and the proanthocyanidins present in cranberry are tannins with a natural defense function against microorganisms, such as those responsible for urinary tract infections (UTI). This berry has a potential curative and preventive effect for various diseases, especially urinary tract infection. Therefore, it becomes relevant to clarify the effect of this natural product on urinary tract infections.
