Ever used Pink Stork Labor Prep Tea?

At my last appointment I was 38+4 and I had only dialated 1 cm and 50% effaced, which is what I was at 35+4. I was so upset that I started doing everything I could to dialate (except sex and castor oil). I bought the labor prep tea way back when I was 25 weeks. I've been drinking 2 cups a day every day since last week. I'm really hoping for some results today at my appointment. Has anyone had good results?

I'm not wild about the taste. I've been drinking it cold, which in my opinion is better than hot. I've been adding lemon juice to counteract the sweetness of the stevia.

Anyone else tried it?
