This is from my blog http://www.veganatgenesis.com  & http://itveganatgenesis.blogspot.com 
I presumed the worsening symptoms I was having were due to a yeast infection. So, I treated what I thought was a yeast infection with over-the-counter Yeast-Guard Suppositories. When it didn't work, figured I had gotten BV (bacteria vaginosis) again. So, I attempted to treat it with VH Essentials BV Treatment- Homeopathic Rime-Release Vaginal insert. While it gave some relief, it didn't .
The itching was still out of control and at times painful. Finally, after a visit to the doctor, I received the diagnosis of Strep B. I was diagnosed with Strep B during my pregancy and received antibiotics during delivery so that my daughter wouldn't receive its detrimental effects.
Determined to end this reoccurring problem of bacterial overgrowth (yeast, BV, and Strep B), through research of herbal remedies, I found the solution that worked for me.
What worked? Alkalizing the body. Restricting and eliminating acidic foods like apple cider vinegar, fruits, and grains. I had to boost my immune system which was low and allowed Strep B to breed and throw my vaginal area off balance.
Eating more green and alkalizing foods combated the acidic environment.
To boost my immune system I took golden seal, colloidal silver, and echinacea.
To kill the overgrowth I took black walnut and garlic capsules.
To alkalize my body, I used Oregon grape root and green foods, which were key to my speedy recovery (a little over a week, but for many it typically lasts two weeks even to a month).
For immediate relief, I also diluted colloidal silver in purified water and used as a douche (a little further than the opening of the vaginal so as not to push bacteria further up). UPDATE: a combination of 1-2 probiotics capsules and water is also effective when douching.
Yes, I was shocked at the recovery as well as the healing power of these simple herbs.
**From my own personal experience I successfully treated Strep B with a whole foods diet and herbal synergy.
