Objective: Artemether is a common anti-malarial drug used in combination with Lumefantrine for the treatment of uncomplicated falciparum malaria. It is also reported to be used as anti-cancer drug; hence it was thought worthwhile to explore its anti-mitotic effects on the onion root tip system. Material and methods: Onion bulbs were grown in tap water where they sprouted 2-3 mm roots. Their mitotic index reading at 0hour was noted then they were transferred to the test solutions.The plasma concentration of the drug is reported to be 184ng/ml; so for testing its effect the drug was added to the water in which onion tips were grown with 92ng/ml (½ plasma concentration), 184 ng/ml (plasma concentration) and 368ng/ml (2×plasma concentration). Results and conclusion: Readings of % mitotic index (MI) were noted at 0 hr and 24& 48hr after putting the onions in the experimental solutions.  It was found that there was depression of the MI% at all the three concentrations when compared to their respective 0hr readings and most of the time the depressions were statistically significant.Regarding the effect of curcumin, it was found that at a concentration of0. 33% and 0.66% curcumin induces MI% depression after 24 & 48hr, but at 1.1%, the depression is less and actually there is a slight increase. Thus it acts as both anti-mitotic and an immunomodulator.
