I was wondering if anyone could tell me whether peppermint tea is safe to drink in pregnancy?

I'm 7 weeks and have had really bad all-day sickness for the last 3 weeks, and have found that Minties seem to settle my stomach. But when the Minties touch my tongue, I start gagging.

Ginger's no good, has always made me feel sick, even at the best of times.

Thanks for any help
