Stevia urticifolia  Thunb. is an underexploited herb possessing bioactive flavonoids, saponins, and terpenoids. The aim of this study was to examine the antiproliferative and toxicogenetic properties of the ethyl acetate extract from  Stevia urticifolia  aerial parts (EtAcSur) upon  Artemia salina , erythrocytes,  Allium cepa  and sarcoma 180 cells and fibroblasts, as well as  in vivo  studies on mice to determine systemic, macroscopic, and behavioral alterations and bone marrow chromosomal damage. The assessment using  A. salina  larvae and mouse blood cells revealed LC 50  and EC 50  values of 68.9 and 113.6 µg/ml, respectively. Root growth and mitosis were inhibited by EtAcSur, and chromosomal aberrations were detected only at 100 μg/ml. EtAcSur exhibited potent concentration-dependent viability reduction of S180 and L-929 cells and antioxidant capacity employing ABTS •  and DPPH • . No previous  in vivo  studies were performed before with the EtAcSur. Signals of acute toxicity were not observed at 300 mg/kg. Physiological and toxicological investigations at 25 and 50 mg/mg/day i.p. for 8 days did not markedly change body or organ relative weights, nor patterns of spontaneous locomotor and exploratory activities. In contrast, clastogenic effects on bone marrow were found at 50 mg/mg/day. EtAcSur was found to (1) produce toxicity in microcrustaceans, (2) capacity as free radical scavenger, (3) antimitotic, cytotoxic and clastogenic activties upon vegetal and mammalian cells, and (4) lethality on both tumor and normal murine cells indistinctly.  In vivo  damage systemic effects were not remarkable and clinical signals of toxicity were not observed, suggesting the significant pharmacological potential of  S. urticifolia  for the development of antineoplastic agents.
