Uh! Hormones feeding candida, that is interesting, it would explain a few emotional upsurges I've had.
My explanation of why candida flares up around the menses is that menses are a mean of cleaning up the body and in the process, we get rid of the candida that had formed in the uterine.
I always start putting a garlic clove, daily, in my vagina, a few days before my menses start so as to avoid highly problematic menses.
