The cytotoxic effect of C. edulis water extract and curcumin (positive control) on HeLa Chang cells. Assays were performed in triplicate and results are expressed as the mean ± standard deviation of three independent experiments. Viable cells treated with different concentrations of the extract did not affect cell survival at 24, 48, and 72 h. Effect of curcumin monitored at same various hours was found toxic to the cells.
