My natropath gave me a concoction from 5 weeks that included raspberry leaf. I was wary, but she did say it was safe. However the tea in the shops is only recommended 2nd or 3rd trimester.
There's a good tea I have called Rooibos and it's a red tea. The women in Sth africa drink it whilst pregnant as it has no caffeine and has alot of health benefits. Very much tastes like black tea. I have it just weak. You can add sugar and milk.
As for the pizza thing, I only go vegetrarian. I am not 100% sure the cooked packaged meats are ok, I would avoid them. Also there are some pregnancy books out there by natropaths that say all the herbs etc you must avoid and what you can have. xo
