For some yes, for others no! Many types of tea and herbal tea can be consumed in moderation during pregnancy; about 2 to 3 cups a day. On the other hand, certain plants contain substances that can be harmful to the fetus.

Some of these can poison the baby, cause congenital defects or even provoke a spontaneous abortion.  Therefore, before consuming any flavoured tea or herbal tea, it is important to read the label and identify which types of herbs are contained in each infusion.
