A lot of those hormones come from our adrenal gland, which as we all know, gives us our nice little "fight or flight" syndrome. Phytoestrogens, (hormones from plants) have helped me the most for PMS. Native American women used to use it for birth control, Wild Mexican Yam, or Black Cohash. I wouldn't use it along with the pill, though, too many hormones. You take it just like the pill, go off it while you're on your period. (Wouldn't rely on it for birth control, ) I used the cream form for a year, and entirely ended my PMS, and shortened my periods. You use 1/4 t. and rub in, if it takes more than 30 sec. to absorb, you need another dose. I have also read that DHEA will balance all the adrenal hormones, but seems to work better for men; haven't tried it yet, myself. Good luck! Cathie P. S. Red Clover contains all 4 phytoestrogens, sometimes I drink the tea. You can buy it, or sometimes I just pick it and make my own. It's the big clovers with the pink-purple flowers!
