I don't know for sure what doses are, but after my first son was stillborn, I put myself on Red Clover leaf tea, along with Nettle leaf and Red Raspberry leaf tea. I generally made one pot of tea from three bags (one bag of each type).
All three of these are uterine tonics that can help regulate and repair your womb. Using these teas, I conceived again right away and carried my second son to full-term with no problems at all.
I would recommend the book "An Herbal for the Childbearing Year" by Susun Weed. You may have to special order it, but it has some valuable information regarding uterine tonics, and (I don't know what you're interested in red clover for, but...) it also provides recipes for preventing pregnancy, getting pregnant, combating morning sickness, helping with your sore breasts, and all the little things that can crop up with a newborn such as colic and cradle cap.
