Methanol extract of C. indica (MECI) leaves showed direct cytotoxicity on Ehrlich ascites carcinoma (EAC) cell in a dose dependant manner and there was significant decrease in the tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice. Hematological profile and biochemical estimations were significantly restored to normal levels in MECI treated as compared to EAC control mice. MECI treatment significantly modulated the tissue antioxidant assay parameters as compared to the EAC control mice. The results revealed that MECI possesses significant dose dependent antitumor potential which may be due to its cytotoxicity and antioxidant properties.
