Yep, Peppermint is one of the herbs that can actually cause your supply to go down if you have too much of it. It can even cause your milk to dry up in some cases. So I stay away from the Peppermint tea I have and just drink Chamomile tea lol
Interesting! I drank peppermint tea all the time while breastfeeding. I always thought it was a healthier alternative to caffeinated varieties! Wish I had known this then... it was a bitch to try and keep my supply high enough to feed my twins!!
