It directly inhibited artrial muscle reduced the maximal driving frequency. which is one of the main components extracted from Sophora flavescens, has displayed anti-cancer activity.

A mixture 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.
Sophora flavanone G obtained from Sophora flavescens was evaluated against more than 10 clinical isolates of methicillin-resistant Staphylococcus aureus
