Has anyone tried herbal medicine to treat mental health issues?

I'm currently seeing a psychiatrist, first one ever for getting a diagnosis I never received as a child. I'm trying to get help with verifying that I have ADHD/OCD tics and possibly ASD (even though this psychiatrist thinks for some reason I actually have schizotypy instead). Have any of you been on herbal medicine from a psychiatrist? I had a poor encounter with a therapist years ago and I'm having a hard time trusting mental health professionals, but this one told me if I couldn't tolerate psychiatric meds, that they had some knowledge in natural approaches. Just wonder if that's actually legit or not.
