A well-known Chinese traditional drug, decoction of wick of sun-flower stem, has been used to treat cancer and certain other diseases.1,2 Animal experiments in mice showed that transplantation of Sarcoma 180 (S180) and of Uterus cervical cancer 14 (U14) were signlflcanly inhibited by this decoction. The Inhibition rates of tumor weight were 33 -81 % and in about 6 - 20% of treated mice, complete tumor regression has been demonstrated. So tar no acute toxic side-effect was noted. This is in contrast to most of the antitumor chemltherapeutic drugs known to produce different degrees of toxlcity or induce Immunosuppression as a side effect. For this reason, we have undertaken the present study.
