Hello again,
There are people on this site that understand all of this so much better than myself.  I know that Dr B used to have a dissertation that she wrote available to purchase - I'm not sure that she still does. You could check by contacting her office.   I can only tell you what matters to me - Conventional medicine offers no "cures".  Nor can they tell you that any of their treatments will definately make you feel better.  They'll throw some numbing pills at you, distend your bladder - the list goes on and on.  If you mention yeast and bacteria, and it doesn't show on their test results, they'll pooh pooh you.  They will not try to balance the whole you. 
Like yourself, when I first started treatment, I only throught my bladder or urethra was sick. When I started peeing bubbles I figured that all would be well quickly.  Then crap started pouring out vaginally - despite the fact that doctors said that the strange odor, discharge, and abnormal pap smears and cycsts weren't related to bacteria or yeast.   Now, odor, discharge, dryness, cyst, are gone - PAP smears have greatly improved.  So, now, I'm almost well?  Then, pretty soon, junk is pouring out of my nose - one time so acidic that it burnt my fingers,  My ears were ringing like crazy, fluid was coming out of them, my face is itching and my eyes are crusted over in the morning, and my sinuses and eyes wanted to pop out.  Now, those symptoms have dramatically improved, the swelling in my eardrums, so severe that for years had completely closed at the end of the canal, is wide open.  My sinus headaches that I used to take sudaphed for nearly every day, are now short lived.  Then, somewhare along the way, I started to hear my intestines gurgle.  It dawned on me that I hadn't heard my intestines gurgle for years.  I'd spent several years on stomach medication, had gotten off of that when i self treated with Aloe Vera Juice (not a good thing to do) and had forgotten that a tummy should occasionally talk to you.  So, I blissfully figured that my tummy was now happy.  WRONG!  Last week I gave birth to the most painful, nasty smelling, disgusting looking mucous stuff that I've ever seen.  Then, the left side of my stomach hurt, then the right side, then my upper stomach had zinging stabbling - Oh, and I was running a low grade fever.  The doctors ran their tests, expecting bacteria from water or food poisoning - NOTHING!  Thankfully, nearly two weeks later, I feel better.
What I'm rather long windedly saying, is that if you're like most of us on this site, your bladder is only a symptom of your whole body being out of balance - probably starting with your intestines.  For whatever reason, they aren't working right - and if they don't work right - the general consenus that I've been able to gleen, is that your immune system isn't working right.  This is why the pro-biotics that you would probably be put on, would help repair your gut while the other herbs would clean out the bacteria and the yeast.  Then, along with the proper food, including red meat  and eggs(used to NEVER eat it - feel so much better when I do) Your body will start to heal and the realization of how truly sick you've become, will probably dawn.  You'll start remembering every strange bizaar symptom that has ever happened to you that was fixed by you or some Dr with a quick band aid - leaving you able to ignore looking for the root of all the little problems.  You'll realize that all of these things, probably including anxiety and depression, are not normal.
Taz, I'm not into worrying about understanding it - probably because I worry about everything else.  I just can't ignore the facts of what my body has done while on this treatment -  it's trying to fix itself.  While true, it seems like one step forward and a half back, I just can't deny that something strange and beautiful is happening.
Long windely - all my best -
