Anti-allergy actions and the inhibition of bacteria and viruses in test tube studies have also been documented with Chinese scullcap.² Some preliminary Chinese human trials, generally of low quality, suggest that Chinese scullcap may help people with acute lung, intestinal, and liver infections, as well as hay fever.³ More extensive clinical research is needed to clearly demonstrate Chinese scullcap’s effectiveness for these conditions.
