Do any folk remedies or herbals help induce labor?

Abstract

Breast stimulation and electroacupuncture help, while other common remedies that have been studied are ineffective, possibly unsafe, or both. Unilateral breast stimulation shortens the time until the onset of labor in women at term (strength of recommendation [SOR]: A, systematic review). Electroacupuncture also may stimulate the onset of labor (SOR: C, observational studies).
