Yes, this works wonderfully for infections caused by E-coli, but not other 
pathogens.  It apparently inhibits the bacteria from attaching to the bladder 
mucous membrane, and they are flushed out of the system.  

I have a better source than health food stores for this, if anybody wants to 
know.  I order ten containers at a time--50 grams.  The suggested use on the 
container is 1 tsp. every two hours in water.  When using the capsules (that's 
all I have seen in health food stores), you would go through an expensive 
bottle in no time.  With this container, you are set for about 14 days.

The infection I have (had?) was not caused by E-coli.  I tried d-mannose 
first, and it didn't work. 

So far, the only thing that has curbed the infection (but not yet the burning 
symptom) has been an NAET treatment for (who would have guessed) parasites.  
I guess Proteus mirabilis is a parasite!
