Ok, thanks for the further info. This is what I've had mommas do, but you do still of course need to take into acct nugglemama's comment about low platelets.
Wk 1- 3 capsules a day for 7 days (starting at 37 wks, or any week after that time)
Wk 2- birth- 1-2 capsules a day until labor begins. If the bottle gives a recommended daily dosage of 1 take the recommended dosage, otherwise take 2 a day.
You would be taking evening primrose, which has natural prostaglandins (like the gel they use in the hospital for cervical dilation, just a much lower dose and from a natural source). I don't recommend more than 2500mg per day, so if the brand you get has a high dosage you'll need to adjust the number of pills you take accordingly. Evening primrose works topically as well, so once labor starts rubbing the oil of 2-3 capsules directly on the cervix can be very beneficial. Oil based herbs can go rancid, like any oil, so if your pill is oil based it should be stored in the fridge. This helps with a cervix that has a hard time dilating. A lot of times the dilation problem is caused by a baby that hasn't dropped, so exercises that help with that and a few visits to a chiro can be beneficial as well.
