Why is it that science and medicine research so much on synthetic chemicals and such yet all these natural items: primerose,cinnamon,aloe era,cumin,etc.... That many of us read on pregnancy website for induction for example haven't been researched the heck out of them? There's so many natural item that by now and how technology is and our advanced medicine that we don't know all about them. It would make sense if we knew as much as we can from these things so we could be more knowledgeable and safe. To me it's just like wth? Why are these things under the "further research is needed" maybe in that research we could find uses to help others with conditions. I don't know but that my rant.
