herbs to induce

So I'm a week late :\ and my midwife has given me some herbs (in liquid form) to take to help induce labor. Maining black and blue cohash. Now I'm not really worried about the safety of them because she's been delicering babies for 20+ years but I was just curious if anyone else had taken those specifically and what the outsome was. Did it really induce do you think it was coincidince
