I thought that was the natural treatment for GBS during pregnancy. I think you are supposed to wrap cheese cloth around the clove to keep it together maybe?
I know that when I was battling a thrush skin infection after a round of antibiotics and steroids (due to an allergic reaction) i took probiotics, garlic oil pills, and echinacea to help beat it back. So, no I believe garlic is used to fight yeast infections.
And hey, it worked.
I could make all sorts of other comments, but I am going to refrain to avoid a possible UAV.
