Pre-eclamspia is a mystery... Doctors are not sure why it happens.. My pregancy with my second child was fine but I was told to not have anymore. I know I am lucky and so is my oldest child. I think that is why I am grateful everyday to be with my kids and to show them that I love them - it's because I came so close to losing my first born and I almost lost my life too. My oldest went into respiratory distress the second night that we were in that horrible hospital - my husband was running around trying to find a doctor and we could not fine one. We sat by my babies side and held an oxygen tube by his face so he could breath. It snowed 3 feet that night and the next day we both were life flighted. No, I do not know about that herb.. I do know that a lot of herbs are just as dangerous as normal medications. I am very cautious with herbs and with medications. I like to be as natural as possible.
