Hi Yvette,
Acupuncture can be used to induce as it stimulates certains points to get your own body producing the hormones (these are the same points they avoid during pregnancy as you don't want to cause early labour). If it comes to induction for me, I am going to try this first. If you go this way though, make sure you use a reputable acupuncturist who is fully qualified and also experienced in obstetric/gynaecological acupuncture.
