I would be very very wary of giving any advice to this woman (not you, Rachel, but your friend). She obviously has a serious medical condition, and anything can interfer with that. Many teas and herbals have clotting properties, which is NOT something this woman need. I'm not sure I would even feel comfortable recommending Red Raspberry Leaf tea--how much vit K is in it? Any? I know alfalfa tea has alot, but what about RRL?
Intercourse is best, as previously recommended. She can start taking Evening Primrose Oil at 36 weeks, one 500mg capsule twice a day, and at night she can poke some holes in one and insert it vaginally. This can help soften her cervix, so that induction will work better.
I also think the idea of accupressure or accupuncture, maybe a day or two before the scheduled induction, is a good idea.
I would stay away from all herbals and teas unless she was woking one on one with a knowledgeable naturopath...there can be alot of interaction with herbs and meds, and this could have devastating effects for her. She is already going to be considered high risk...if she has an OB with an itchy trigger finger, that is even worse. If they know she is taking herbs, but they aren't supplied with good info re: these herbs, then any problem that might occur will be blamed on the herbs, the practioner, and the mom. I think the OB should definately KNOW if themom is taking something, that is important. I just want to emphasize the potentials.
Does this woman have a doula? She seems to be a prime candidate for one!
