Query: It works!

As someone who has very adverse reactions to antibiotics I was very hopeful that this product would work. Not only does it help to prevent UTIs when taken daily, I have also used it to treat a UTI and was symptom free within 24 hours. Read the research. This is the most logical way to treat a UTI caused by E Coli bacteria (the most common cause of UTIs), with absolutely no side effects.
