Sally, there are sooooo many herbs out there that are not good for pregnant woman to take. Even green tea is not highly recommended. You should ask your Dr. next time you are there and see what he says about it then tell her your findings.
I cannot understand why people would put any risk to their babies. I have bad allergies and used to use Flonase until I read that you should not use it if you are pg or plan to become pg. I think taking all precautions is the way to go.
