Ella, I have the same thoughts as you re herbs. I am afraid to take herbs that are very estrogenic like PM. I took red clover almost 10 years ago, not for NBE but for acne. And it helped really good. Within 14 days I had completely clear skin. But then I missed my period and I freaked out and thought I was pregnant (was not). It was due to red clover. And I stopped taking it then... 
I am afraid of the side effects of PM too. I read that women with developing cyst at the ovary, breast, and uterus should not take PM. I have a cyst in my right breast and in my uterus. So no, I won't take it.
