I have no doubt that Uny will come to the truth of this matter; as I have followed her for years. She excels at critical thinking; one of my weaknesses. I highly respect any advice she offers. Perhaps you have misjudged me in this.
In respect to herbs and the natural path, I always rush in where fools would dare to tread. Many times without due diligence; just because I'm too excited to wait. However, where there is pregnancy involved, like the poster agrees, I would lean greatly toward caution.
