Midwife brew... to encourage labor???

Anyone thinking about trying this to bring on labor towards the end??? I am scared of the castor oil but just want others views!!!! No need to preach on it we all know what the studies say about castor oil so for anyone wanting to be judgmental this post is not for you! Any other natural methods to prepare body is welcome??? Like EPO, pineapple core, dates, RLT, etc!
