You can use an Iodine
bolus. Soak a cotton ball in distilled water or saline solution. Add some Lugol's, insert vaginally and leave in for ten minutes. Stains, so keep something under you.
Strep B vaginally is dangerous under two conditions: One if you are pregnant and delivery is imminent. The other is if you are running a fever - in that case they will give you antibiotics, and some strains are antibiotic resistant (another reason not to take antibiotics).
Group B Strep (GBS) if often transferred back and forth from the colon to the vagina. Usually it causes no trouble. It is not like E-Coli, or the strep that causes Strep Throat. Usually antibiotics orally do not help. I would suggest you try the iodine bolus or the garlic remedy mentioned below.
"Group B Strep in Vagina
By: Harold Oster
My doctor told me I have group B strep in my vagina. What are the dangers? Should I take antibiotics to get rid of it?
There are many different groups of streptococci bacteria. Group A strep, or Streptococcus pyogenes, causes strep throat and skin infections, including necrotizing fasciitis, commonly known as the "flesh-eating bacteria" infection. Group B strep, or Streptococcus agalactiae, harmlessly colonizes the genital tract of up to 40 percent of women. Although the bacteria are present, they do not cause disease. Certain groups of people are susceptible to infectious disease from Group B strep, however. They include newborns, women who have just given birth, and certain other adults, usually those who have underlying medical problems...
...You did not mention whether you are pregnant. If you are not, then nothing should be done. Group B strep is very common, and it does not cause many problems in women outside of pregnancy. In addition, it is very difficult to eradicate the bacteria. A course of oral antibiotics is not very effective. If you are indeed pregnant, then your treatment and the treatment of your baby should proceed along the lines I described above. Bear in mind that there are several different acceptable strategies for managing the situation, however."
"When Garlic is inserted vaginally for seven or eight nights (and/or eaten daily) it will convert a large percentage of women who previously cultured positive(+) to GBS negative(-). This is particularly true if the culture is taken immediately after the last day of treatment.
Garlic cloves differ in their amount of active, anti-microbial ingredient, called "allicin". The active ingredient is released upon cutting or crushing the clove. The active ingredient is toxic to GBS as well as yeast and cancer cells. If a woman has damaged vaginal skin inserting garlic may result in a burning sensation"
