Uva ursi has been used by the Native Americans since the second century as a remedy for urinary tract infections. It contains hydroquinone, a chemical that has antibacterial properties. It also contains tannins, which have astringent properties that aid in the reduction of inflammation and toning of the bladder. It is also effective against bacteria found in the intestines that cause kidney and bladder infections, including e. coli. It increases the volume of urine, which helps to flush out microbes and toxins.

Cautions and Limitations of Use:
· When taking uva ursi, avoid eating acidic foods, such as pineapple, citrus, lemon and tomato. Uva ursi requires alkaline urine to be effective as an antibiotic. Another way of making your urine alkaline is to take some baking soda.
· Pregnant woman should not take uva ursi, because it is an oxytocic that can stimulate contractions of the muscles of the uterus. It is also a diuretic that encourages water loss.
