I just wrote this blog, i hope it helps you :) I highly recommend getting the book by Stephanie Fritz she is a MW that uses EO"s in her birth center. I am only ever talking about doterra as i know they are safe. I would not trust other ones until research is done :)
Book is called Essential oils fro Pregnancy, Birth & Babies :)
Hope this helps!
