Ashwaganda or other medications for stuttering?

Ashwaganda or other medications for stuttering? Hey guys. I’ve stuttered since I was little now I’m 17. I’ve been looking for anything that can help with stress, anxiety, or nervousness. I’ve found like ashwaganda and L theanine. Has anyone tried it? Any side effects? Did it work and would you recommend it? And if you know of some others that can work?
