Arctostaphylos uva ursi is a plant species of the genus Arctostaphylos(manzanita). The leaves of this small shrub have been used as an herbal folk medicine for centuries. Bears are particularly fond of the fruit, which explains its Latin name, "Uva-ursi,” which means "bear's grape."
Because Uva ursi requires an alkaline urine for its antimicrobial properties to work, those taking Uva ursi should avoid eating acidic foods like citrus, pineapple, tomato. Prescription drugs such as ammonium chloride, non-prescription products such as vitamin C, herbals such as rose hips, and foods such as cranberry juice may all make the urine more acidic in nature. Potentially, taking a urine acidifier may lessen or destroy the antibacterial effects of Uva ursi.
