I used to have a problem with recurrent b.v. and I got rid of it by a few different methods. I douched with Colloidal Silver /grapefruit seed extract combo and I also took yeast fighters and the product Candex. To replenish the acididity the vagina needs and restore the ph balance once the infection was gone I douched with vinegar. Now I maintain my non-bacterial state by supplements by mouth only. No more infections!
