[Anti-tumor effects of heiji (radix Astilbes chinensis]

The experimental results indicate that the herb Heiji is able to suppress the growth of transplantable tumor (S180) in mice by 30%-51% (P < 0.01), prolong the vital stage of the EAC transplanted mice by 44% (P < 0.01) and raise the lymphocyte transformation rate in lower concentrations in vivo. It follows that Heiji has positive anti-tumor effects and deserves further research as a new anti-tumor herb.
