Thyroid Help? Ashwagandha

I've noticed while reading magazines the past few months the same term that keeps cropping up that has shown success with some people with thyroid disease. The word is "ashwagandha." I am seriously interested in researching this more. I have to be careful because 1) who the heck just takes something they don't know anything about without researching; and 2) I have to be careful what I take while taking thyroid medication because I react oddly to other medications now.

Has anybody heard anything about Ashwagandha and thyroid?
