Can herbal supplements make you have a miscarriage at 5 months?

Yes, however...: There are many herbs with the potential to induce a miscarriage. However, they are much more likely to do so in the first trimester. They could also induce premature labor in late pregnancy. At 5 months it is possible but less likely. See http://www.Localharvest.Org/blog/39774/tags/women & http://www.Localharvest.Org/blog/39774/tags/pregnant most of these are ok in small amounts (like cinnamon).
