here's what i've learned. . . believe me, in the past, i've tried EVERYTHING. . . red raspberry isn't supposed to put you into labor, it's supposed to help tone your cervix and uterus to make labor more productive. . . i took it with both pregnancies, and honestly i think it was probably a waste of $$. i drank it and also took it in pill form. with my son, i took castor oil. . .(i was already 2 cm and 80% effaced though) and it did put me in to labor, but it was AWFUL. . .i had major cramping and diarrhea with it. . . from what i've learned, it won't even work unless you're very close to going into labor already and your body is doing stuff already. . . i really don't recommend it. . . i probably tried every wives tale in the book when i was pregnant with my daugher- eggplant parmesan, pineapple, red raspberry, castor oil, sex, walking, exercise, you name it, i tried it. . .guess what. none of it worked. she came out when she was good and ready, right on her due date. ;-)
good luck though! it'll be over before you know it!!
