Raspberry Leaf Tea should only be avoided if you have a history of miscarriage, pre-term labour etc. It's a uterine tonic, which is very good for you in pregnancy, but of course, see a naturopath first to eliminate any possible health conflicts. It's even useful for morning sickness but there is so much conflicting advice over it's use in the first trimester. I had it with Marisa though. In the tea form and especially from the supermarket, they aren't that strong of a dose anyway.
