Is it safe to take herbs while I'm trying to get pregnant?

Q: I'm trying to get pregnant. Is it OK for me to take herbs, and will herbs help speed things up?

A: With no data showing they increase pregnancy rates and no federal regulation of their labeling, many fertility specialists don’t recommend using herbs. “Herbs can trigger allergies, be toxic or irritating, or just hang out in the body too long,” says Sarah Berga, M.D., a reproductive endocrinologist and associate dean at Wake Forest School of Medicine in Winston Salem, NC. “We don’t know which ones in particular to stay away from, because they haven’t been well studied, but it’s definitely a buyer-beware market.”
