I just want to thank you for existing. I've suffered from menstrual problems from out-of-whack hormones since puberty, including a period that essentially didn't stop--I would bleed for months at a time. Thanks to you answering a question regarding breast size and estrogen production, I discovered black cohosh. Within 4 days of taking it, my period finally stopped. I've been taking it for about six weeks now, and just experienced the first normal period of my life. (I'm 26 now, btw.)
