Natural yeast infection remedies

I have a yeast infection (yay!). So to save $20 by not purchasing Monostat, I'm looking for natural ways I can fix the infection.
I found a recipe where you just mix coconut oil, lavender essential oil and tea tree essential oil, put it in the fridge to let it harden, and then insert it into the vagina. Has anyone tried this? I found different variations of this recipe in several places, so I know it has worked for many women.
Do you know of other natural remedies for a yeast infection?
Thanks!
