Raspberry leaf tea/ pills

Anybody has tried raspberry leaf tea or pill to induce labor? I hear you suppose to start it by 36 weeks? If you did how much did you take? Can you please tell me your experience With it? My last and first pregnancy I was pregnant for ever and then was medically induce by 41 weeks. My labor was 63 hours long. That’s why this time I am trying to find things to speed up the process.
