Has anyone been using this extract to help repair the damaged myelin sheath? Mice studies for years show that the extract has compounds that stimulate repair of damaged neurons and myelin sheath. Very interesting to read about. Makes no sense there haven't been human studies, but we do share most of our DNA with mice. Dr. Paul Stamets works with National Institutes of Health and has an extract he sells cheaply at fungi.com. He has written many books, including Mycelium Running...I ordered it.
