As far as I know, there should be no adverse effects, but to be sure, ask a herbalist, or even the manager of the store...thezy should have a rudimentary knowledge base of their products...
I took Milk Thistle when I needed HRT..... and there was no problem....
You could also ask about herbal alternatives to anti-depressants.... Vitex Agnus castus is very good, as is sage tea....
But please don't just take my word for it...
This site is very good for herbal supplement information....
