Neuroprotective in focal cerebral ischemia.

A mix of Sophora flavescens and licorice (Glycyrrhiza glabra) gave better liver protective and anti-hepatocarcinogenic effects than licorice or Sophora alone. In addition, glycyrrhiza + sophora had a protective effect on immunosuppression, a strong non-specific anti-inflammatory effect, and reduced the incidence of sodium and water retention, protecting against pseudohypercorticosteroidism.
