Cordyceps are fascinating to me. Makes me wonder what the first person that ate it was thinking. I commonly see it in the Chinese herbal stores but have not tried it. I came across the article below that states its immunomudulatory effect of regulating the immune system in autoimmune diseases.
www.ncbi.nlm.nih.gov/books/NBK92758/
"Cordyceps sinensis can help strengthen the immune system by stimulating natural killer cell activity. Uniquely, Cordyceps Sinensis has also shown the ability to impose bi-directional control, calming overactive immune systems and improving autoimmune diseases such as diabetes and lupus. For diabetics, it also helps by reducing the lipoprotein in blood."
