I got it from Walmart. It's in the aisle with the vitamins. My OB recommended it for me. some start using it as early as 36 weeks. it's completely safe and nothing like castor oil. @adevlin2
it helped my cervix open and helped with dilation. I took 4 capsules a day as well as inserted 2 vaginally nightly. I started this at 39 weeks even. I was only 1.5 cm dilated. By my 3rd day of use I had dilated to 4cm. @adevlin2
