Evening primrose oil....take the tablets orally and break them open and insert them up by your cervix before you go to bed. They help soften the cervix.

Sex... an orgasm makes the uterus contract and semen has prostaglandin in it that helps soften the cervix.

Labor ball....try sitting on it and rolling your hips in counter clockwise or clockwise circles. Helps open the pelvis.

Walking....helps the baby lower into position.

These are the safest and easiest ways to get labor going, however, none of them will work unless your body is ready anyway. If your cervix isn't "ripe" then you just have to wait it out. If everything is getting ready to go anyway then one of these might help push you over the edge. I was 10 days late ( Tessa was due July 3 2008, and I had her the 13). I tried everything and even when I went in to be induced I was only dilated to one, hadn't started effacing and she hadn't engaged. At least I felt like I was doing something proactive when I tried to get things going. Good luck, and have a wonderful, safe, healthy, happy delivery, and many blessings to the new little one.

This is a very interesting topic to me. I have read in places where people have intentionally given pregnant women caster oil throughout their pregnancy to make them have a miscarriage/abortion. I do not know if that is true but if it is, you will not find me reaching for the caster oil at 38 weeks. I would much rather try the other options, like walking and sex. Way more fun than drinking something nasty.
