Midwife brew drink- EDIT

I’m currently 27 weeks and 3 days! This pregnancy has been so painful and due to personal reasons I was wondering if I can drink the midwife brew WITHOUT the Castor Oil.. (I plan on talking to my doctor about it) I know the Castor Oil is not safe and i won’t use it. But can the juice itself help maybe?

EDIT: I’m not planning to induce labor now. I wanted to try to induce labor around 38/39 weeks. I have health problems and complications in this pregnancy. I am not selfish this is my rainbow baby and I would never hurt my child or not think about my baby💔my baby is measuring 2 weeks ahead as well so she is big. I am a tiny person and with complications and having to do Physical Therapy every week it’s so painful🥺I am so grateful for my baby and I love every second of feeling her kick but my body is feeling severe pain as well due to me being really skinny and little.. I just wanted to know if the drink was okay when I’m around 38/39 weeks
