Anyone used Lions Mane???

Summary

Lion's Mane mushroom at 1 gram three times daily produced a rapid initial response in an ME/CFS patient: within about half an hour, severe skin and nerve burning eased by roughly 50%, and by the third day brain swelling sensations had dropped about 80% with improved anxiety and mood. By the fourth day hives developed along with a spike in symptoms, leading them to stop after four to six days. They report considering retrying at a lower dose but give no follow-up on whether they did or what happened. No illness duration or baseline severity grade is stated.
