Study hypothesis
Bacterial vaginosis is a polymicrobial clinical syndrome where the Lactobacillus are replaced by anaerobic bacteria, Gardnerela vaginalis and Mycoplasma hominis.
The study hypothesis is that metronidazole and aroeira have similar efficacy in the treatment of bacterial vaginosis, but aroeira has less impact in the vaginal flora, because it is a natural substance, extracted from a tree caulis.
Ethics approval
Ethical Commitee in Research of the Instituto Materno Infantil (c/o Prof Fernando Figueira) approved in March 2007.

Intervention
The participants will be randomised into two groups of 150 women:
Control group: Metronidazole gel 0.75%, intravaginally, once a day for seven days.

Drug names
Metronidazole, Shinus terebinthifolius Raddi (called aroeira)
Primary outcome measures
To compare the frequency of the clinical (Amsel Criteria) and bacteriological (Nugent criteria) cure assessed at baseline and after their next menses (approximately one month after therapy) between the two groups.
Secondary outcome measures
1. To compare the frequencies of the adverse effects of the two drugs
2. To compare the frequencies of the effects in the vaginal flora, observing the presence of lactobacillus in Papanicolaou smears at baseline and after their next menses (approximately one month after therapy)
3. To compare the frequencies of the effects of the two treatments by the presence of bacterias and fungi in vaginal cultures at baseline and after their next menses (approximately one month after therapy)
