A report suggests that Yokukansan (TJ-54), also called yi-gan san in Chinese may help treat schizophrenia.  Yokukansan, a traditional herbal medicine, has a therapeutic effect against neuropsychiatric disorders and several open-label clinical studies have shown yokukansan is effective at treating schizophrenia or schizophrenia-like psychosis. Animal studies and neurobiology also reveal that yokukansan and its ingredients have antipsychoticproperties.
