I had a UTI once that I cleared up in a day drinking lemon water and taking chewable cranberry supplements from the local health food store. Hers is further along, so I'd add colloidal silver and garlic to that. Chop the garlic into pill sized pieces and swallow, it's amazing for any infection. Top all of that off with LOTS of probiotics, and remain on them for awhile if she took a whole round of antibiotics.
