The main aim of the present work was to investigate the cytotoxic and antitumor effects of aqueous extracts of leaves of I. suffruticosa obtained by infusion and maceration as well as to evaluate the toxicological properties. Aqueous extracts did not exhibit cytotoxicity against HEp-2 (human epidermoid cancer cell) cell lines by MTT method. From the aqueous extract by infusion, the toxicological assay showed low order of toxicity. The antitumor effect of aqueous extracts by infusion (64.53%) and maceration (62.62%) against sarcoma 180 in mice at a dose of 50 mg kg−1 (intraperitoneally), based on low order of toxicity was comparable to the control group, which showed 100% development. Considering the low order of toxicity and that it is highly effective in inhibiting growth of solid tumors, the aqueous extracts of leaves of I. suffruticosa may be used as an alternative anticancer agent. %U http://www.hindawi.com/journals/ecam/2007/856238/abs/
