This study was designed to observe the anticancer activity of propolis on human rectal (HRT-18) and human colon (HCT-48) cancer cell lines in vitro, and on sarcoma-180 cells in vitro. The proliferation of HRT-18 and HCT-48 cancer cell lines was potently inhibited in proportion to the concentration of propolis. The survival time of the mice inoculated with sarcoma-180 cells was increased modestly by the administration of propolis compared to the control. Those observations suggest that propolis has anticancer effects against some of the cancer cell lines in vitro and in in vitro.
