It worked for me. My son came 8 days early :)
Red raspberry leaf "tea"'s benefit is toning smooth muscles. Your uterus is a smooth muscle. The idea is to help your contractions to be more efficient and coordinated during labor. The raspberry tea from the grocery store is not the same as what you would get at a natural foods store or an herb shop. Make sure you're getting the good stuff - it doesn't taste like raspberries. :)
I've been drinking a cup of raspberry tea 3-4 times a week for the last 4 weeks. I'm 38 weeks now and I think I'll try to drink a cup every night now. I also drink others teas besides raspberry like peppermint and other green teas
I can't say for sure if it worked with my daughter or not. However I drank that, and used blue n black cohosh (yuck never again) and evening primrose oil my daughter was late BUT my labor was 8hrs start to finish. The only thing I can say is hrs before labor started hubby and I had sex.... I think that's what really did it! :) good luck!!!!
