What kind of dosage is appropriate when taking Uva ursi?

I took a CDSA (Comprehensive Digestive Stool Analysis) and found that I have a 4+ rating for Klebsiella pneumoniae. I've read that Uva ursi is good for eliminating this, is it better to take capsules or make a tea? And what is the correct dosage per day, and for how many days/weeks, etc.? Thanks for all your help!
