Broad question but..: I know of no known interactions between these herbs and oral contraceptives. As to whether these have any affect on hormones, that is a very broad question. I found one website that says lemon verbena can help regulate menstrual cycles and help with PMS, but it did not provide references so I don't know if research confirms this. Lemon balm is thought to help regulate thyroid hormone levels.
