So how do you know which teas you should and shouldn’t have? American Pregnancy Association breaks down teas into two distinct categories: herbal teas and non-herbal teas. Under non-herbal teas, all the teas fall under two further subcategories, black teas (which include English breakfast and Earl Grey) and green teas. American Pregnancy Association also notes that oolong teas should also be avoided due to them being a combination of both black and green teas.
Insider cites that while pregnant people should drink tea sparingly, options like ginger tea are okay to take for morning sickness. The publication does note that folks should avoid both peppermint and chamomile tea during their first trimester as they could be harmful to the baby. Raspberry or red leaf teas are a no-go as well, but are said to be great for postpartum consumption as they are rich in calcium (via Insider). What about teas that are made from spices like cinnamon and licorice? Insider says to avoid those at all costs to lessen any chance of pregnancy complications.
