Feverfew is safe during lactation according to all of my reference material. The reason that it is contraindicated during pregnancy is due to the potential side effect of uterine stimulation. This mom also might want to consider adding White Willow Bark to her feverfew for migraines, I have found it to be much more effective. If you require further information, please do not hesitate to contact me direct. Wishing you health and wellness! Tami Karnes, One With Nature Certified Herbalist P.O.
