What are the best natural herbal remedies for a UTI?

Urinary tract infection aka bladder infection. I got this a week ago and have been taking AZO from over the counter at Wal-Mart. I also have been upping my usual dosage of cranberry juice on top of cranberry tablets. It has been years since I got one of these and I wonder if there's an better herb that can tackle this immediately. I don't believe in going to doctors for something I can doctor myself.
