TBH, I have no idea how the EPO works orally, other than that it is recommended to do also. You can start using it at around 36 weeks both orally and internally. For the internal dose start with one to 2 capsules inserted high into the vagina, by 38 weeks you can up it to 3 capsules, and you can do it morning and night. I only ever did night time though. I find right before bedtime best as it gives it a chance to pool and soak the cervix. Make sure you wear a pad or panty liner though, because what goes in, will come out

With my last pregnancy I was 3 cm dilated before I even went into labour and my cervix was so ripe and easy to stretch. Has to be a bonus.
