I have had great success helping my clients with Chronic Urinary Tract Infections (UTI’s) using blueberry in the form of a concentrate.
The dosage for the prevention of UTI’s is ¼ cup of the pure blueberry concentrate stirred into one liter of water and sipped throughout the day.
As an herbalist I also encourage my clients to have an herbal mix to treat and prevent Urinary Tract infections. I like the blend from Herbalists and Alchemist UT Compound by David Winston which includes herbs in a wonderful combination that helps to clear the infection and help sooth the bladder. Typical dose is: 20-40 drops (1-2 ml) taken 3 times per day over a period of a few months (although you need to speak with an herbalist the dosage may need to change depending on weight and age and condition of person).
Please understand this: it is NOT that blueberries are antibacterial and kill the bacteria responsible for UTI’s; rather, it’s that the blueberries have a component that inhibits bacteria from proliferating and living on the bladder wall.
Here is what the research says, “The compounds responsible for inhibition of bacterial adherence are called proanthocyanidins. The proanthocyanidins found in blueberries prevent harmful bacteria from adhering to the walls of the urinary tract. Blueberries contain certain molecular compounds that help prevent urinary tract infections; however, blueberries do not have direct killing effects on the bacteria. Instead, blueberries prevent urinary tract infections by altering the bladder tissue in such a way that the bacteria are not able to adhere for long enough to establish an infection. Therefore, when the bladder is emptied during urination, the bacteria are flushed out along with the urine, and an infection is avoided.
