"What Your Doctor May Not Tell You About Menopause:
The Breakthrough Book on Natural Progesterone"
The books explain how most women in the industrialized world today are estrogen dominant, why (including stress and synthetic estrogen's in our food and environment), the effects, and what to do about it.
What upsets me the most are the drug companies who created synthetic estrogen and progesterone (so they can patent it), for birth control pills and hormone replacement therapy, when there are natural options (bio-identical progesterone) which do not have toxic side effects.
