Interesting, Tina. I have not heard anything about it but I will follow this thread as I have a friend who’s daughter was diagnosed with early signs of potentially developing Hashimotos so she will probably need to be aware of this if it is true. Thank you for bringing it up.
(P.S. If I had to guess, any autoimmune condition should avoid immunostimulating herbs out of caution. I have also heard disagreement whether elder is immunomodulating or immunostimulating so, again, interested in experienced feedback.)
