Herbal tea

So, I'm almost 24 weeks pregnant and on Saturday I drank Bigwlow's lemon ginger tea bc I am still nauseated almost everyday. That being said I had what I thought was indigestion and my back was hurting. Low and behold I read the damn box and it has lemongrass and licorice root in it! I only had one cup and since then threw the box away but I'm just wondering if anyone else has made this mistake? Everything I have read says that one cup shouldn't do damage to the baby but of course I worry... 😩
