Need opinions from mommy's who drank red raspberry leaf tea.

Ambreal
So my midwife suggested I start drinking rrlt at 36 weeks to help my cervix and labor. . this is the kind i bought. Have any of you mommy's used it? If so what were your results? Did it speed up labor, make it less painful, or bring labor on when it want close before? I've drank one cup so far.. Just hoping i have good results. Thanks ladies.
