I solved this with a Grapefruit-Seed-Extract douche .. Grapefruit Seed Extract. I got mine at a local health foods store, it is what the Homeopath employed by the store recommended. Here are the instructions..
Boil filtered water for 12 minutes - 2 cups
12 drops of GSE
Vitamin E capsule for lubricant.
Cool to body temp before using.
Use for 7 days.
Use at night right before bed.
I also took 6 grams of vitamin C orally in divided doses for the 7 days.
This worked for me. My Doctor kept giving me Rx's for yeast infection even though the tests kept coming back negative.
