“Ginseng is another common herbal remedy that has shown promising results in the treatment of psychosis. It promotes general brain health and enhanced cognition, and reduces the “fuzzy-headed” feeling that modern pharmaceuticals can give sufferers of psychosis. If you’re looking for a place to begin your herbal antipsychotic therapy, then ginseng is a solid place to start.”
I’ve heard one of the healthiest teas you can drink is matcha. I don’t know if it has benefits for psychosis. It’s pretty expensive too. It does have L-Theanine which is supposed to be good for anxiety.
