Cranberry is a member of the same family as bilberry. It is from North America and grows in bogs. The ripe fruit is used.

Cranberry has been used to prevent kidney stones and “bladder gravel” as well as to remove toxins from the blood. Cranberry has long been recommended for persons with recurrent urinary tract infections (UTIs).

Active constituents of Cranberry

Cranberry prevents E. coli, the most common cause of UTIs and recurrent UTIs, from adhering to the cells lining the wall of the bladder.

This antiadherence action renders the bacteria harmless in the urinary tract. Recently, the proanthocyanidins in the berry were shown to have this antiadherence action. Cranberry has been shown to reduce bacteria levels in the urinary bladders of older women significantly better than placebo, which may help to prevent future infections. Other preliminary studies in humans suggest cranberry can help people with urostomies and enterocystoplasties to keep them clear of mucus buildup.

How much Cranberry is usually taken?

People often take one capsule or tablet of a concentrated cranberry juice extract (400 mg) two to four times per day.6 Several glasses (16 ounces) of a high-quality cranberry juice each day can approximate the effect of the cranberry concentrate. Cranberry tincture, in the amount of 3–5 ml three times per day can also be taken.
