Are there any ways to naturally speed.up labor?

A few: Some women swear by accupuncture, others by having intercourse. Still others say spicy food or castor oil will bring on labor. Another natural way would be to perform nipple stimulation, thus releasing your natural oxytocin. Sadly, none of these methods have been proven to be 'the one' and are used anecdotaly. Having said that, if it works, it works.

Option - Acupuncture: The world health organization places induction of labor under the category of "diseases, symptoms or conditions for which acupuncture has been proved-through controlled trials-to be an effective treatment" acupuncture has been used for this purpose for thousands of years.
