bladder infection
"Seems to be working for me, but time will tell if it helps to prevent recurring infections, as like many, I am very susceptible to UTI's.  I have no antibiotic resistance that I know of, but I would rather not take them if I can avoid it!  Re: concerns about formation of formaldehyde in the gut, that sounded scary to me too, but after a bit of reading I learned that formaldehyde does not accumulate in the body.  The body metabolises it to formic acid, which acidifies the urine and kills the bugs (it is an antibacterial and often used as a preservative in food).  That said, formaldehyde is a known carcinogen so I will be monitoring my use."
