I'm going to try Ashwagandha. Is it good?

I'm going to try Ashwagandha. Is it good? I just want to lessen my anxiety and see if my stuttering would decrease too. Sure meditation helps but ain't no way Imma stand in front of the class being silent and make silly breathing meditation while standing. Chew gum doesn't have any impact on my stutter it just makes me looks disrespectful.
