Yeah, you have to eat multiple fresh whole pineapples within like an hour or so. It's almost impossible. With my first baby, at 38 weeks, I used 4 evening primrose oil capsules in the vagina. That was the night of July 3rd. I went into labor when I woke up on the 4th and had my daughter early morning on the 5th.
My doctor said u had to eat 7 or 8 whole pineapples, The skin and core also. And I got half way through and only got a very sore mouth for about two weeks.
