It is safe to take Raspberry Leaf for the second and third trimesters - up to three cups a day, or 1.2 to 2.4g/day in tablet form. In the lead up to labour you can increase the dosage of tea to six times daily. It doesn't have any safety issues, except that it should be avoided in the first trimester, and it should be taken away from mineral supplements as it can reduce your absorption of the minerals.
