I am Katherine Abdun-Nur,RN,Lactation Educator. I run the Breastfeeding Support Service for a small rural hospital in Southern Oregon. Today I am in search of information regarding the maternal intake of peppermint tea as one of our staff nurses says that it is contraindicated in breastfeeding women due to it's effect on babies. I'm not clear on what these effects are supposed to be. I have searched the Lawrence and Auerbach texts, and have put in a call to an out-of-area colleague who was unavailable today. Is there anything to this? Thanks.
