Lions Mane are very unique medicinal mushrooms because they stimulate the production of nerve growth factor. NGF keeps nerve cells healthy and can repair nerve damage. I grow Lions Mane mushrooms and have made dual extracted tinctures that helped with my overall homeostasis, as well as feeling more "sharp" when it came to word recovery and sentence formation, like, not being at a loss for a word which was sometimes happening from time to time.
My hubby's nerve damage to his back is pretty much gone. He can sleep on his right side again, and I never hear him complain of pain in that location. I would add the tincture to a glass of juice in the morning. Always consider your source, and don't be scared to try your hand at growing them! They are quite simple to grow.
