Are suppositories such as boric acid, coconut oil, and rephresh helpful for the vagina?

Depends: If you are having problems such as frequent yeast infections, this could help. If you are having vaginal dryness, could be temporary help. If no problems, not needed. If you have problems, please consider an evaluation and discussion with your doctor.

Approved meds: Boric acid is sometimes prescribed by doctors but in a specific amounts for specific times. I would not recommend using it without a doctors guidance. Refresh is available over the counter and can be used at your discretion.
