Are cinnamon, Indian cloves and chamomile teas abortive?

I wonder if the cinnamon teas, Indian carnation, chamomile for example are abortive teas, or this is just popular belief. Thank you very much in advance.
Expert answer:

It probably has some effect on the female reproductive system, but I do not know if it's about to cause abortion, I just know that cinnamon tea and cloves are contraindicated in pregnancy.
