The purpose of the  paper was to investigate the  in-vitro antigiardial activities (Giardia lamblia) and cytotoxicity (MTT assay) of  ethanol extract of Cyperus rotundus L (whole plant). The ethanol extract of C. rotundus were screened for their antigiardialal activities  (Giardia lamblia) and screened for their cytotoxicity using 3- (4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT), obtained from C. rotundus (whole plant) ethanol extract which exhibited 100% inhibition  at a concentration 500 µg/ml after 96 h; this was compared with Metronidazole which gave 95% inhibition at concentration 312.5 µg/ml at the same time against Giardia lamblia. MTT assay verified the safety of the examined extract. In conclusion: These studies conducted for C. rotundus (whole plant) were proved to have potent activities against Giardia lamblia trophozoites in vitro. Index Terms- In vitro, antigiardial, Giardia lamblia, Metronidazole, cytotoxicity (MTT-assay), Cyperus rotundus L, (whole plant).
