I'll throw in my anecdote. I was suffering from hand tremors that had no obvious root cause. It was getting bad enough I was starting to spill drinks while holding (relatively) heavy glasses. Saw a doctor and got screened for all the potential causes and nothing came back. I decided to try lions mane and took it daily for about 6 months. That was 3 years ago and my hands are steady as they've ever been. Ymmv.
