Yes it works for most people. You can never say anything works for ALL people because everyone is different. It is an option that wouldn't hurt you to try, it is safe in correct doses. In the best case scenario, it will trigger labor, make it a quick labor and prevent you from tearing. All that is not guaranteed, but those are the common claims of taking it for the right amount of time. I plan to start taking it orally at 36 weeks daily and then vaginally at 38-39 weeks. How many weeks are you?
There aren't many studies on it because, frankly, natural products like EPO is not profitable for pharmaceutical companies, so like with all natural products, they get dismissed as being ineffective. However, that is not the case. Natural options like this DO work and they work the BEST!
